Best Email Marketing Software 2026
Last updated: May 2026
Quick Answer: The best email marketing software in 2026 depends almost entirely on how your business is structured — not on which platform has the most features. Brevo is the strongest value for most small and growing businesses. ActiveCampaign wins on automation depth for B2B. Klaviyo is built for e-commerce above ~$50k/month revenue. Mailchimp, once the default choice, has raised prices and cut free-plan limits repeatedly since its 2021 acquisition — and is now among the most expensive options at scale. This article names the real costs at 2,500 and 10,000 contacts, something most comparison sites won’t show you.

Email marketing is one of the few digital channels where ROI is genuinely measurable and consistently strong — $36 to $45 back for every dollar spent, depending on industry, according to data from Litmus. But that return assumes you’re on the right platform. The wrong one quietly bleeds money in ways that don’t appear in marketing dashboards: contacts you no longer email still counted toward your billing tier, automation features that exist on paper but require three plan upgrades to access, and pricing that looks reasonable at 500 subscribers and absurd at 10,000.
I’ve reviewed and used email marketing platforms across clients ranging from two-person e-commerce operations to 200-person SaaS companies. This guide reflects that: it’s written for buyers, not for affiliate revenue. Every tool listed here includes a frank assessment of where it stops making sense — information competitors with monetized recommendation engines structurally cannot give you.
Eight platforms are covered in depth. If a tool belongs on this list, it’s here. If it doesn’t, it isn’t.
How We Evaluated These Platforms
The evaluation criteria reflect what actually determines ROI in email marketing, not what’s easiest to feature in a spec table.
Pricing model transparency — not just the entry price, but what you pay at 2,500 and 10,000 contacts. Most platforms hide this because the gap between “starts at $9/month” and “costs $175/month for 10,000 contacts” is significant. I’ve built this out in the Email Platform Cost Reality Index below.
Pricing model type — the split between contact-based pricing (you pay per subscriber stored) and email-volume-based pricing (you pay per email sent, regardless of list size) is one of the most important and least-explained distinctions in this category. It materially changes which platform is cheaper depending on how frequently you send.
Deliverability — the ability to land in the inbox rather than spam is the most important technical specification, and almost every comparison article ignores it. Third-party inbox placement rate testing shows meaningful variation between platforms: ActiveCampaign and MailerLite consistently score 92–93% inbox placement rates in benchmark tests; Mailchimp has scored as low as 82% in the same methodology.
Automation depth at entry-level pricing — what you can actually automate on the cheapest paid plan, not the enterprise tier.
Honest limitations — what each platform genuinely can’t do well, and who should go elsewhere.
The Email Platform Cost Reality Index (EPCRI)
The most important table in any email marketing roundup is the one most competitors don’t publish: what you actually pay as your list grows.
The figures below show the approximate monthly cost at two critical list sizes — 2,500 contacts and 10,000 contacts — at each platform’s most common paid tier. All prices are approximate and based on publicly available pricing data verified in May 2026. Contact each platform directly for exact quotes on your usage pattern, especially at higher volumes.
Pricing model key: C = contact-based (pay per subscriber stored) | V = email-volume-based (pay per email sent)
| Platform | Model | ~2,500 contacts/mo | ~10,000 contacts/mo | Free tier? |
|---|---|---|---|---|
| Brevo | V | ~$18/mo | ~$25/mo | Yes — 300 emails/day, unlimited contacts |
| MailerLite | C | ~$17/mo | ~$32/mo | Yes — 500 subs, 12,000 emails/mo |
| ActiveCampaign | C | ~$49/mo | ~$79/mo | No — 14-day trial |
| Kit | C | ~$49/mo | ~$99/mo | Yes — 10,000 subs (limited features) |
| Klaviyo | C | ~$60/mo | ~$175/mo | Yes — 250 contacts only |
| HubSpot | C | ~$50/mo | ~$200/mo+ | Yes — limited |
| Omnisend | C | ~$16/mo | ~$59/mo | Yes — 250 contacts, 500 emails/mo |
| Mailchimp | C | ~$27/mo | ~$135/mo | Yes — 250 contacts only (as of 2026) |
Important caveat on Brevo: Brevo prices by email volume, not contact count. The figures above assume sending 4 emails per month to your full list (~10,000 emails at 2,500 contacts, ~40,000 emails at 10,000 contacts). If you send more frequently, your Brevo cost scales. If you have a large list you email occasionally, Brevo becomes dramatically cheaper than any contact-based platform.
Important caveat on Mailchimp: Mailchimp counts unsubscribed contacts toward your plan limit unless you manually archive them, meaning the effective cost is typically 20–40% higher than the tier’s listed price for accounts with normal list churn.
This table is the most important thing in this article for most buyers. Bookmark it, run the math for your actual list size, and use it as your baseline before reading the tool profiles.
Who This Guide Is For
This roundup is built for three business profiles that together represent the vast majority of email marketing buyers:
Small businesses and growing brands (list size under 10,000, sending 2–4 campaigns per month) — the sweet spot for Brevo, MailerLite, and Omnisend. Tools where you don’t need a dedicated marketing ops person to get value.
B2B service businesses and SaaS companies — nurture sequences, lead scoring, CRM integration, and behavioral triggers matter more than template libraries. ActiveCampaign and HubSpot are the natural homes.
E-commerce operators — revenue attribution, abandoned cart flows, Shopify/WooCommerce native integration, and purchase-behavior segmentation are non-negotiable. Klaviyo and Omnisend are built specifically for this.
If you’re a large enterprise with a dedicated email ops team and a six-figure annual marketing budget, this guide will still be useful for framing — but your conversation should be with Salesforce Marketing Cloud or Braze directly.
The 8 Best Email Marketing Platforms in 2026
1. Brevo — Best Overall Value for Growing Businesses
Starting price: Free (300 emails/day, unlimited contacts) | Paid from $9/month
Pricing model: Email-volume-based (pay per email sent, not per contact stored)
Best for: Small to mid-sized businesses with large lists that send campaigns 1–4× per month
Visit Brevo
Brevo’s core competitive advantage is structural, not feature-based: it’s one of the only major platforms that prices by email volume rather than contact count. That single design decision makes it the right default choice for any business with a large list that doesn’t email daily.
Run the numbers on what that means in practice. A business with 25,000 contacts sending four campaigns per month generates 100,000 email sends. On a contact-based platform like Mailchimp, you’d pay for 25,000 contacts regardless of how often you email them — likely over $200/month. On Brevo, you’d pay for 100,000 emails sent, which lands somewhere around $65/month on the Business plan. That differential grows as your list grows.
Beyond the pricing model, Brevo is notably comprehensive for its price point. Even on the free tier, you get marketing automation, a built-in CRM, web tracking, and live chat support. The Starter plan ($9/month for 5,000 emails/month) adds A/B testing and removes the daily sending cap. The Business plan (from around $18/month) unlocks landing pages, predictive send-time optimization, and advanced reporting. A built-in SMS channel and WhatsApp marketing come included in the platform without requiring separate integrations — useful for businesses running cross-channel campaigns without the budget for omnichannel enterprise tools.
Deliverability is solid. Brevo runs its own email infrastructure rather than reselling third-party relay services, and its domain reputation management tools are more accessible than most competitors’.
What Brevo does well: The free tier is genuinely useful — unlimited contacts, 300 emails per day, automation, and CRM access. Very few platforms give you this at zero cost. For businesses growing from zero, it’s the most generous runway in this roundup.
The CRM is functional without being complex. It’s not HubSpot, but for small businesses that need basic pipeline tracking alongside email campaigns, it eliminates the need for a separate CRM subscription.
Multichannel coverage is real rather than tokenistic. SMS and WhatsApp aren’t afterthoughts — they’re integrated into the same automation builder as email, with unified contact records.
Who should look elsewhere: Brevo’s email-volume pricing works against you if you’re a high-frequency sender. A newsletter that emails 15,000 subscribers five days a week — 75,000 sends per week, 300,000 per month — will find contact-based platforms cheaper at that cadence. Calculate your actual monthly send volume before committing.
Template variety and design quality trail behind MailerLite and Mailchimp. If aesthetic polish in email design is a significant priority and your team doesn’t have a designer, you may find Brevo’s template library limiting.
E-commerce integration depth doesn’t match Klaviyo or Omnisend. Shopify and WooCommerce are supported, but the native data models and purchase-behavior segmentation aren’t as sophisticated.
2. ActiveCampaign — Best Automation Depth for B2B and Service Businesses
Starting price: Starter from $15/month (annual) for 1,000 contacts
Pricing model: Contact-based
Best for: B2B companies, SaaS, and service businesses needing complex multi-step automation
Visit ActiveCampaign
ActiveCampaign occupies a specific and defensible position: it’s the most capable automation builder available below enterprise pricing, and it ships with a functional CRM from the Plus plan upward. For B2B businesses running multi-stage lead nurture sequences, or service businesses managing customer lifecycles across months, it’s the most cost-effective way to get sophisticated automation without paying for HubSpot’s full suite.
The automation builder is the product’s defining characteristic. Where most platforms offer simple trigger-action sequences (“contact opens email → send follow-up”), ActiveCampaign supports conditional branching, split testing at the automation level, site-behavior triggers, lead scoring that feeds back into automation routing, and 900+ pre-built workflow templates. In practice, this means a B2B SaaS company can build a sequence that qualifies leads by engagement, routes high-intent prospects to sales, and continues nurturing everyone else — without requiring a separate marketing automation platform or writing custom integrations.
Deliverability is among the strongest in this category. In independent inbox placement testing, ActiveCampaign consistently scores around 93%, which is 10+ percentage points above Mailchimp’s reported 82% benchmark. For businesses where inbox placement directly affects revenue, that gap is material.
Pricing is contact-based and scales with list size. The Starter plan ($15/month at 1,000 contacts on annual billing) provides core email marketing and basic automation — enough for solo operators or early-stage teams. The Plus plan ($49/month at 1,000 contacts) is where the platform becomes genuinely powerful: CRM, lead scoring, conditional content, and deeper automation logic. For most B2B businesses, Plus is the right entry point, not Starter.
What ActiveCampaign does well: The automation builder has no real ceiling at mid-market pricing. Competitors like MailerLite and Brevo have usable automation; none of them approach ActiveCampaign’s conditional logic and branching depth.
Lead scoring is built into the platform, not an add-on. A contact’s score can trigger different email sequences, sales alerts, or CRM pipeline updates — a workflow that would require custom development or expensive integrations elsewhere.
CRM integration is native, not bolted on. Contacts in email sequences and contacts in sales pipelines are the same records, updated in real time. This eliminates the synchronization lag and data inconsistency that comes from integrating a separate CRM.
Who should look elsewhere: There is no free plan. The 14-day trial gives you access, but if you’re not ready to pay within two weeks, you lose everything. For businesses not yet generating consistent revenue from email, starting on Brevo or MailerLite and migrating to ActiveCampaign later is a reasonable path.
The interface has a learning curve. Not prohibitive, but a solo operator with no marketing ops background should expect one to two weeks before they’re running their first multi-step automation confidently. If simplicity is the priority, MailerLite or Kit will serve better.
Pricing accelerates quickly at scale. At 25,000 contacts, ActiveCampaign Plus runs approximately $187/month on annual billing — competitive with Klaviyo but substantially more than Brevo for equivalent contact volumes.
3. Klaviyo — Best for E-Commerce Above ~$50K Monthly Revenue
Starting price: Free (250 contacts) | Paid from ~$45/month (1,000 active profiles)
Pricing model: Profile-based (active profiles, not all contacts)
Best for: E-commerce brands running on Shopify, WooCommerce, or Magento with revenue-driven email programs
Visit Klaviyo
Klaviyo isn’t trying to be the best email marketing platform in general. It’s trying to be the best email marketing platform for e-commerce specifically, and it largely succeeds. The Shopify integration is the most native in this category — not a webhook-based data pipe, but a proper bidirectional sync that makes purchase history, product catalog data, and real-time browsing behavior available as segmentation and trigger conditions inside Klaviyo’s automation builder.
The practical difference shows in what you can build. A Klaviyo flow can trigger when a contact views a product more than twice without purchasing, adds it to cart, and abandons — with each step in the sequence personalized to the specific products involved, priced in real time from the connected Shopify catalog. That level of purchase-behavior segmentation is available in other platforms, but requires significantly more configuration work.
Predictive analytics are built in and based on actual transaction data. Klaviyo can estimate a contact’s predicted customer lifetime value, the date of their next likely purchase, and their risk of churning — and these predictions feed directly into segment definitions, meaning you can create a “high-LTV, about-to-churn” segment and build a dedicated retention flow without exporting data or running external models.
Since February 2025, Klaviyo has moved to active-profile-based pricing, which charges for contacts who can receive messages rather than all contacts stored. This is more honest than Mailchimp’s approach of billing for unsubscribed contacts, but the costs still scale steeply: approximately $45/month at 1,000 profiles, $100/month at 5,000, and $400/month at 25,000. That trajectory makes Klaviyo expensive for businesses in the 1,000–10,000 contact range relative to alternatives.
What Klaviyo does well: Revenue attribution is best-in-class. Klaviyo attributes revenue from email clicks to actual Shopify orders with configurable attribution windows, giving you accurate per-campaign and per-flow revenue figures. This is the metric that justifies email marketing budget, and no competitor tracks it with the same fidelity.
SMS and email live in the same platform, with unified data. A contact’s email engagement history affects their SMS cadence and vice versa — the kind of cross-channel consistency that requires expensive integrations in other platforms.
The segmentation engine handles complex behavioral conditions that most platforms simplify away. You can build a segment of contacts who purchased in the last 90 days, spent more than $150, haven’t opened an email in 30 days, and are in a specific geographic region — and that segment updates dynamically.
Who should look elsewhere: The price-to-value ratio only justifies itself above a certain revenue threshold. If email drives less than 15% of your e-commerce revenue or your monthly revenue is below $50,000, the analytics depth Klaviyo provides is more than you can act on. Omnisend provides e-commerce-specific automation at 60–70% lower cost and is the right starting point.
Klaviyo is purpose-built for product-based e-commerce. Service businesses, SaaS companies, B2B teams, and content creators will pay for Shopify-specific infrastructure they never use. ActiveCampaign or Brevo serve those use cases better.
The learning curve is real. A solo founder who needs to send a monthly newsletter shouldn’t be in Klaviyo. The platform rewards teams with dedicated email operators.
4. MailerLite — Best for Simplicity, Design Quality, and Controlled Costs
Starting price: Free (500 subscribers, 12,000 emails/month) | Paid from $10/month
Pricing model: Contact-based
Best for: Small businesses, bloggers, content creators, and anyone who wants professional results without complexity
Visit MailerLite
MailerLite occupies the position Mailchimp held five years ago: a clean, well-designed platform that doesn’t require a marketing background to use effectively, priced for the businesses it’s actually serving. The drag-and-drop editor is among the best in the category for visual quality, the automation builder covers the majority of what a small business needs, and the pricing scales predictably without the hidden cost traps that plague Mailchimp.
The free plan is genuinely functional. At 500 subscribers and 12,000 monthly emails, you can run welcome sequences, basic automations, landing pages, and A/B tests — features that would require a paid tier on most competitors. The main limitation is the absence of pre-built email templates on the free plan, which pushes you toward building from blocks or upgrading.
Paid plans start at $10/month for 500 subscribers on the Growing Business plan, which unlocks templates, unlimited automations, A/B testing, and newsletter monetization. At 10,000 subscribers, the Growing Business plan runs approximately $32/month — less than a quarter of what Klaviyo charges at the same list size.
Deliverability is strong. Independent testing places MailerLite’s inbox placement rate at approximately 92%, in the top tier of this roundup. For a platform positioned at smaller businesses, that’s a meaningful competitive advantage — often, cheaper tools sacrifice deliverability, and MailerLite doesn’t.
What MailerLite does well: The editor produces visually polished emails without requiring a designer. The template library covers the main use cases — newsletters, product launches, promotional campaigns — with clean, mobile-responsive designs. For small businesses without in-house design resources, this matters.
Pricing is the most predictable of any contact-based platform in this roundup. No hidden fees for unsubscribed contacts, no separate charges for transactional email (handled through sister product MailerSend), no opaque overage charges. What you see on the pricing page is approximately what you pay.
Multi-language and RTL language support is built in — relevant for businesses serving multilingual audiences, a detail larger platforms often handle poorly.
Who should look elsewhere: MailerLite’s integrations ecosystem is thinner than Mailchimp’s or HubSpot’s. If your tech stack includes less-common CRM or e-commerce tools, check the native integrations list before committing — Zapier fills many gaps, but at additional cost and complexity.
There’s no built-in SMS, no built-in CRM beyond basic contact management, and no multichannel coverage. For businesses that want a single platform for email, SMS, and basic CRM, Brevo is the better choice.
E-commerce capabilities are limited to Shopify and WooCommerce abandoned cart flows. If you need the kind of purchase-behavior segmentation Klaviyo provides, MailerLite won’t get you there.
Advanced automation — deep conditional branching, lead scoring, CRM pipeline integration — isn’t part of the product. For B2B businesses with complex nurture requirements, ActiveCampaign handles things MailerLite simply doesn’t support.
5. Kit (Formerly ConvertKit) — Best for Creators and Newsletter Operators
Starting price: Free Newsletter plan (up to 10,000 subscribers) | Creator from $33/month (annual) for 1,000 subscribers
Pricing model: Subscriber-based
Best for: Bloggers, independent journalists, course creators, and newsletter operators monetizing their audience directly
Visit Kit
ConvertKit rebranded as Kit in 2024. The product philosophy didn’t change: it’s built for creators who treat their email list as a direct business asset, not a marketing channel for another product. That distinction shapes everything about the platform — including some trade-offs that make it the wrong choice for businesses outside that category.
The free Newsletter plan is the most generous in this roundup by subscriber count — 10,000 subscribers at no cost, with unlimited landing pages, forms, audience tagging, and the ability to sell digital products and subscriptions directly. The significant limitations: only one basic visual automation, no email sequences, no A/B testing, and Kit branding on outgoing emails. As a starting point for a creator with an audience but not yet generating revenue, it’s a reasonable runway.
Paid plans distinguish themselves from the free tier primarily in automation depth and commerce features. The Creator plan ($33/month annual for 1,000 subscribers, $39/month monthly) unlocks automated sequences, visual automation builder, third-party integrations, and free migration support. The Creator Pro plan ($66/month annual for 1,000 subscribers) adds subscriber scoring, newsletter referral system (useful for audience growth), and priority support.
Pricing scales with subscriber count on all paid plans. At 10,000 subscribers, Creator runs approximately $99/month, and Pro runs approximately $166/month. Unlike Mailchimp, Kit doesn’t charge for duplicate contacts or unsubscribes — clean, predictable scaling with no hidden billing surprises.
What Kit does well: Audience monetization tools are the best in the category for creators. Kit Commerce allows direct sales of digital products, paid newsletter subscriptions, and courses from within the platform. The economic model — creator builds audience, creator monetizes audience — is directly supported rather than bolted on.
The subscriber scoring system on Creator Pro is genuinely useful for newsletter operators tracking engagement. It feeds into segmentation and automation routing in ways that help content-first businesses understand which subscribers are most valuable.
Tag-based subscriber organization is more flexible than list-based management. Contacts can have multiple tags — “podcast listener,” “purchased course,” “from Twitter,” — which allows sophisticated segmentation without maintaining separate lists.
Who should look elsewhere: Kit is built for audience-centric creator businesses. SaaS companies, e-commerce brands, B2B service businesses, and traditional small businesses will find they’re paying for creator-specific features (monetization, referral program, audience analytics) while missing features they’d actually use (CRM integration, e-commerce automation, lead scoring).
The price-to-automation ratio doesn’t compete with ActiveCampaign. At $99/month for 10,000 contacts, Kit’s automation is solid but not sophisticated. ActiveCampaign provides materially more automation depth at comparable price points for non-creator use cases.
There’s no built-in SMS, no transactional email, and no multichannel capability. If your business needs to reach contacts across more than one channel, Kit isn’t the platform.
6. Mailchimp — An Honest Assessment of the Default Choice
Starting price: Free (250 contacts, 500 sends/month as of 2026) | Essentials from $13/month for 500 contacts
Pricing model: Contact-based
Best for: Businesses already deeply integrated with Mailchimp’s ecosystem, or teams that have evaluated alternatives and determined Mailchimp’s interface familiarity justifies the premium
Visit Mailchimp
Mailchimp is the platform most people start with, and it’s the one most businesses should seriously consider leaving as they grow. That’s a blunt statement, and it needs supporting evidence.
Since Intuit acquired Mailchimp in 2021 for $12 billion, the platform has raised prices or reduced free-plan limits in nearly every subsequent year. The free plan deteriorated from 2,000 contacts and 12,000 monthly sends in 2022, to 500 contacts in 2023, to the current 250 contacts and 500 monthly sends as of January 2026. Automation was fully removed from the free tier by mid-2025. In April 2026, legacy plan users (accounts created before May 2019) received an 11–13% price increase. These aren’t isolated adjustments — they’re a consistent directional signal from the parent company.
The current pricing is structurally disadvantaged compared to alternatives at every tier above Essentials. At 10,000 contacts, Mailchimp Standard runs approximately $135/month. MailerLite charges approximately $32/month for the same list size with comparable features. Brevo, at four-times-per-month sending frequency, runs approximately $25/month. Mailchimp’s interface and brand recognition don’t justify a 4–5× price premium for most businesses.
There’s also a billing mechanism most users don’t discover until they’re already paying: Mailchimp counts unsubscribed and non-subscribed contacts toward your plan limit unless you manually archive them. For accounts with normal list churn — some unsubscribes every month — this means the effective cost of any tier is meaningfully higher than the listed price. A list of 10,000 nominal contacts might have 1,500 unsubscribes accumulated over time, pushing you into a higher billing tier for contacts you’re not emailing.
Deliverability benchmarks place Mailchimp’s inbox placement rate at approximately 82% in third-party testing — meaningfully below the category leaders. For businesses where inbox placement directly affects revenue, this is a material consideration.
What Mailchimp still does well: The interface is genuinely intuitive. For teams with high turnover or no dedicated marketing staff, Mailchimp’s familiarity lowers onboarding friction in ways that competitors with more complex interfaces don’t.
The integration ecosystem is extensive — 300+ native integrations, including many less-common tools. For businesses with unusual tech stacks, Mailchimp often supports native integration where competitors require Zapier.
Social media scheduling, built-in content optimizer, and the e-commerce connection to Shopify and WooCommerce are real features that work. If your business actually uses all of them, the platform provides more surface area than the price premium suggests.
Who should look elsewhere: Any business with a contact list over 1,000 that hasn’t locked in meaningful pricing should run the comparison before their next renewal. At 5,000 contacts, the cost gap between Mailchimp and Brevo or MailerLite is typically $80–$120/month — $960–$1,440 per year for roughly equivalent functionality.
Any business that relied on Mailchimp’s free plan for basic automation and discovered it was removed in 2025. That feature erosion trend isn’t reversing.
Any business where inbox placement rate matters. If you’re sending promotional email and a meaningful fraction of it lands in spam, the platform cost doesn’t matter — the revenue cost is larger.
7. HubSpot Marketing Hub — Best When Email Is Part of a Broader CRM Investment
Starting price: Marketing Hub Starter from $20/month per seat | scales significantly with contact volume
Pricing model: Contact-based, with seat-based components
Best for: B2B companies that are already using or seriously evaluating HubSpot CRM, and need email tightly integrated with sales pipeline data
Visit HubSpot
HubSpot’s email marketing product is not designed to compete with Brevo or MailerLite on price. It’s designed for businesses that have already decided to build their customer data infrastructure on HubSpot — where the email marketing product’s value comes from its native access to CRM data, not from the email editor itself.
When email and CRM are in the same system with shared contact records, you can do things that integration-based workflows can’t fully replicate: trigger an email sequence when a deal moves into a specific CRM pipeline stage, suppress marketing emails for contacts with open support tickets, or personalize email content based on fields that only exist in the CRM record. For B2B businesses where sales and marketing need to operate on shared data, that native integration eliminates a category of friction.
The tradeoff is cost. HubSpot becomes expensive quickly as contact volumes and required features grow. Marketing Hub Starter covers the basics; anything approaching sophisticated marketing automation typically requires Professional ($890/month for 2,000 contacts, billed annually), which is priced for mid-market companies with dedicated marketing teams. Most small businesses evaluating HubSpot are not comparing it to Brevo — they’re comparing it to the cost of running HubSpot CRM plus a separate email tool, and finding the bundled approach justified.
What HubSpot does well: CRM-email integration is native and genuinely seamless. Contact records, deal history, and email engagement live in one place. This isn’t a selling point — it’s table stakes for a platform at this price. But it’s the reason businesses choose HubSpot over alternatives.
The reporting and attribution modeling is more sophisticated than standalone email tools. HubSpot can attribute web traffic, contact form submissions, and sales pipeline progression to specific email campaigns in a single reporting interface.
The platform grows with the business. From free CRM to Marketing Hub Starter to Professional is a coherent upgrade path with no data migration — a meaningful operational advantage for fast-growing companies.
Who should look elsewhere: Any business that isn’t also using HubSpot CRM, or that doesn’t have specific reasons to want native CRM-email integration, will overpay significantly for what they get. ActiveCampaign provides comparable automation depth at lower cost with a functional CRM included from the Plus plan upward.
Small businesses with straightforward email needs — monthly newsletter, welcome sequence, occasional promotional campaign — have no use for HubSpot’s complexity and will find Brevo or MailerLite more than sufficient at a fraction of the cost.
8. Omnisend — Best for E-Commerce Under ~$50K Monthly Revenue
Starting price: Free (250 contacts, 500 emails/month) | Standard from ~$16/month for 500 contacts
Pricing model: Contact-based
Best for: Shopify, WooCommerce, and BigCommerce stores that need e-commerce-specific automation without Klaviyo’s price premium
Visit Omnisend
Omnisend occupies the space between general-purpose email platforms and Klaviyo: purpose-built for e-commerce, with native connections to Shopify, WooCommerce, and BigCommerce, pre-built abandoned cart, welcome series, and post-purchase flows, and a combined email-plus-SMS platform — at pricing that makes sense for stores that aren’t yet generating enough revenue to justify Klaviyo.
The pre-built e-commerce automation library is the product’s best argument. Abandoned cart flows, browse abandonment triggers, cross-sell and upsell sequences, and post-purchase review request campaigns are available as ready-to-deploy templates that connect to your store data. For a store operator without dedicated marketing operations, the difference between “I can build this eventually” and “I can deploy this today” is significant.
SMS is built into the platform and shares contact records with email. Running an abandoned cart flow that starts with an email and follows up with an SMS if there’s no response is a native capability, not an integration project.
At approximately $16/month for 500 contacts, Omnisend Standard is one of the most affordable entries into proper e-commerce email automation. The price at 10,000 contacts (~$59/month) is roughly one-third of what Klaviyo costs at the same list size, for a product that covers the majority of automation use cases for stores in the $10,000–$50,000 monthly revenue range.
What Omnisend does well: The setup-to-first-automation time is the fastest in the e-commerce category. Pre-built workflows with store-connected templates mean a new Shopify merchant can have an abandoned cart sequence live within hours, not days.
Pricing is clean and competitive. No hidden contact charges for unsubscribes, no separate SMS platform fees, and a predictable cost curve as contact count grows.
Who should look elsewhere: Klaviyo is the better choice once you’re generating consistent e-commerce revenue above ~$50,000/month and email drives a meaningful fraction of it. At that point, Klaviyo’s predictive analytics, advanced LTV segmentation, and deeper Shopify data access generate ROI that covers the price difference.
B2B businesses, SaaS companies, and service businesses have no use for Omnisend’s e-commerce automation templates. ActiveCampaign or Brevo serve those needs.
Free Email Marketing Platforms: What’s Actually Available in 2026
Most free-tier email marketing is constrained enough to qualify as a trial rather than a permanent option. The exceptions:
Kit Newsletter plan — up to 10,000 subscribers with basic features. Genuine free tier for audience-building, if you don’t need automation sequences.
Brevo free plan — 300 emails per day (roughly 9,000 per month) with unlimited contacts. Includes automation, CRM, and basic landing pages. Best free plan for businesses that already have a list and send infrequently.
MailerLite free plan — 500 subscribers, 12,000 monthly emails, automation, landing pages. The best-featured free plan for small lists.
Mailchimp free plan — now capped at 250 contacts and 500 monthly sends, with no automation. At this point, it functions as a product tour, not a usable free tier.
Klaviyo free plan — 250 contacts, 500 emails per month. Useful for testing the interface; not a realistic free option for operating a list.
For businesses starting from zero, MailerLite’s free plan is the most generous relative to what you’re likely to need in the early months. Graduate to Brevo or MailerLite paid when your list exceeds 500 subscribers or you need automation depth beyond basic welcome sequences.
How to Choose: A Decision Framework for Real Buyers
The EPCRI table in Part 1 handles cost. This section handles fit — which platform is right for your use case, regardless of price.
Step 1: Identify Your Pricing Model Risk
The first question isn’t “which platform has the best features” — it’s “which pricing model works for my send frequency.”
You should prefer email-volume-based pricing (Brevo) if: You have a large contact list that you email once or twice a month. Newsletters, membership organizations, community lists, and seasonal businesses all fit this profile. At 20,000 contacts sending twice per month, Brevo costs approximately $18–25/month. A contact-based platform charges for 20,000 contacts regardless of how often you email them.
You should prefer contact-based pricing (everyone else) if: You email your full list multiple times per week. At very high send frequency — a daily email to 5,000 people — a contact-based platform at ~$100/month competes favorably with Brevo’s volume-based charges for 150,000 monthly sends.
The break-even frequency depends on your list size, but as a rough rule: if you’re sending more than 12 emails per month to your full list, run the math on both models before deciding.
Step 2: Match Platform to Business Type
| Business Type | Primary Recommendation | Alternative |
|---|---|---|
| E-commerce, $10K–$50K/month revenue | Omnisend | MailerLite |
| E-commerce, $50K+/month revenue | Klaviyo | ActiveCampaign |
| B2B SaaS or service business | ActiveCampaign Plus | HubSpot Starter |
| Content creator or newsletter | Kit | MailerLite |
| Small business, general use | Brevo | MailerLite |
| Agency managing multiple clients | ActiveCampaign or Brevo | MailerLite (clean UI for client handoff) |
| Already using HubSpot CRM | HubSpot Marketing Hub | ActiveCampaign |
| Nonprofit or charity | Brevo (most generous free tier) | MailerLite |
Step 3: Validate Deliverability for Your Sending Domain
Deliverability is the most underrated criterion in this evaluation. A platform with 82% inbox placement rate versus one with 93% means that for every 1,000 emails sent, you’re losing 110 more to spam with the lower performer. At 10,000 monthly sends, that’s 1,100 emails per month not reaching inboxes — a marketing cost that doesn’t show up in your platform subscription.
All platforms in this guide support SPF, DKIM, and DMARC authentication, which are prerequisites for reliable deliverability on any modern platform. The difference in inbox placement rates reflects shared infrastructure quality, proactive list hygiene policies, and how aggressively each platform enforces sender reputation standards. Before committing to a platform, run a test campaign through a deliverability testing tool like Mail Tester or GlockApps to validate your actual inbox placement on your sending domain.
Step 4: Account for Migration Cost
Switching email marketing platforms is not trivial. The technical migration — exporting contacts, importing to new platform, replicating automations — is manageable. The operational cost is in automation rebuild time. A complex ActiveCampaign account with 40+ automation sequences might take a full week to reconstruct on a new platform. Factor this into any cost comparison: if Brevo saves you $80/month but costs 40 hours to migrate to, the payback period is roughly 5 months at $20/hour equivalent time cost.
Most platforms offer free migration assistance for accounts above a certain size — Kit for lists over 5,000 on paid plans, ActiveCampaign on a case-by-case basis. Use it.
Frequently Asked Questions
What’s the best free email marketing software in 2026?
MailerLite’s free plan is the best for small lists starting from scratch — 500 subscribers, 12,000 emails per month, automation, and landing pages are all included at no cost. Kit’s free Newsletter plan is the best option for creators with a larger existing audience (up to 10,000 subscribers), though automation depth is limited. Brevo’s free plan is best for businesses that already have a large contact list and send infrequently (300 emails per day, unlimited contacts stored).
Is Mailchimp still worth it in 2026?
For most businesses, no. The free plan has been reduced to 250 contacts and 500 sends per month, with all automation removed. Paid plans are 3–5× more expensive than competitors at equivalent list sizes. Deliverability benchmarks place Mailchimp below the category leaders. Businesses already heavily integrated with Mailchimp’s ecosystem may find switching costs justify staying in the short term — but the directional trend since the Intuit acquisition is consistent: higher prices, fewer features at lower tiers. A direct comparison between Mailchimp Standard and MailerLite Growing Business at 10,000 contacts shows MailerLite at approximately $32/month versus Mailchimp at approximately $135/month, for overlapping feature sets.
What’s the difference between contact-based and email-volume-based pricing?
Contact-based pricing charges you based on how many subscribers are stored in your account, regardless of how many emails you send. Email-volume-based pricing (used by Brevo) charges based on the total number of emails you send per month, regardless of how many contacts are stored. Contact-based pricing benefits frequent senders with relatively small lists. Volume-based pricing benefits businesses with large lists that send infrequently. A community with 30,000 members but monthly sending frequency will pay dramatically less on Brevo than on any contact-based platform.
Which email marketing platform has the best deliverability?
Independent inbox placement rate testing places ActiveCampaign and MailerLite in the top tier, at approximately 92–93% inbox placement rates. Brevo performs well given its price point. Mailchimp has scored as low as 82% in some third-party tests. However, deliverability is significantly affected by your sending practices — list hygiene, authentication setup, engagement rate management — as much as by the platform itself. The best platform for deliverability is one that you configure correctly for your sending domain, with proper SPF, DKIM, and DMARC records in place.
Does email marketing still work in 2026?
Yes, and by a significant margin over most alternative channels. Litmus research consistently finds email generating $36–45 in return for every dollar invested. The channel benefits from a structural advantage: you own your subscriber list, which isn’t subject to platform algorithm changes that affect organic social reach or paid ad platform policy shifts. The businesses that get the least from email marketing are typically those on platforms that charge for contacts they’re not emailing, don’t enforce list hygiene, or run automation sequences that aren’t calibrated to subscriber behavior. The platform choice matters less than the program quality — but a platform that doesn’t charge you to store inactive contacts, and that delivers reliably to inboxes, is the foundation everything else sits on.
Can I switch email marketing platforms without losing my automations?
Contacts transfer cleanly via CSV export and re-import on any platform. Automation workflows do not transfer — they must be rebuilt. If you’re migrating from a platform with limited automation (Mailchimp free tier, MailerLite simple sequences) to one with more sophisticated options (ActiveCampaign, Klaviyo), the migration is an opportunity to improve your workflows rather than just replicate them. Give yourself two to four weeks of parallel operation — keeping the old platform active while setting up the new one — before switching off the original.
What is deliverability, and how does it affect my email program?
Email deliverability refers to the rate at which your sent emails reach subscribers’ inboxes rather than being filtered to spam or blocked entirely. A 93% inbox placement rate means 7 out of every 100 emails don’t reach the intended inbox. Across a list of 20,000 subscribers, that’s 1,400 contacts who never see your email. Deliverability is affected by your sending domain’s authentication setup (SPF, DKIM, DMARC), your list hygiene (removing inactive and bounced addresses), your sending reputation on the platform’s infrastructure, and the content of your emails themselves. Platform infrastructure quality is a baseline factor — some platforms maintain better shared IP pool reputations than others.
Is there a truly unlimited email marketing platform?
No platform is truly unlimited, but some are more generous than others. Kit’s paid plans include unlimited email sends with no per-email charges, though costs scale with subscriber count. MailerLite includes monthly send limits (12× your contact count on the Growing Business plan), which are rarely binding for normal sending frequencies. “Unlimited” in this category typically means the send cap is high enough that it’s not a practical constraint — not that there’s literally no ceiling.
What should I look for when comparing email template builders?
The most important factors are: whether the editor produces mobile-responsive emails by default (all major platforms now do this), how much design flexibility you have without knowing HTML, whether your brand assets (colors, fonts, logo) can be saved and reused without re-uploading each campaign, and how the email renders across major clients — Gmail, Outlook, Apple Mail — which handle HTML differently. MailerLite and Klaviyo have the best template editors for visual quality; Brevo’s is more functional than attractive; ActiveCampaign’s editor is solid but not a selling point.
Which platform is best if I’m just starting out?
Start on MailerLite free if your list is under 500 subscribers and you want to learn email marketing with a low-friction tool that won’t cost you anything until you’re ready. Start on Brevo free if you have an existing list and want automation, a CRM, and SMS in one place at no initial cost. Avoid Mailchimp’s free tier — at 250 contacts with no automation, it’s too restricted to learn from effectively. Move to a paid plan when your revenue from email justifies the expense, or when you hit the free-tier limits on whichever platform you started with.
Final Verdict
Eight platforms, one question for each buyer: which one costs the least while covering what you actually need?
Brevo is the default recommendation for most small and growing businesses. The pricing model is structurally advantageous for the majority of sending patterns, the free tier is the most operationally useful in the category, and the multichannel coverage (email, SMS, WhatsApp, CRM) eliminates subscription costs for ancillary tools.
ActiveCampaign is the right choice when automation sophistication is the primary requirement and budget allows for it. B2B companies, SaaS, and service businesses with complex nurture sequences will find it the only non-enterprise option that handles their needs natively.
Klaviyo earns its price for e-commerce operations above ~$50,000/month in revenue where email drives a meaningful share of that revenue. Below that threshold, Omnisend provides 80% of the capability at a fraction of the cost.
MailerLite wins on value-for-money within contact-based pricing. If you’re not on Brevo’s volume model, MailerLite is the most cost-efficient contact-based platform at every list size tested.
Kit is purpose-built for creators and serves that use case better than any general-purpose alternative. If your business model is audience-first — newsletter, course, digital products — Kit is the right home.
Mailchimp is the hardest recommendation to make. The brand is still strong, the interface is familiar, and the integrations are broad. But the pricing trajectory since 2021 has been consistently worse for customers at every tier, and the deliverability benchmarks don’t justify the premium. Evaluate it honestly against your actual current spend and list size.
HubSpot is justified when email is one component of a broader HubSpot investment. As a standalone email marketing platform, it’s overpriced relative to what it offers.
Omnisend is the entry point for e-commerce email that doesn’t require Klaviyo’s sophistication or budget.
