7 Best Email Marketing Platforms With Generous Free Tiers (2026)

MailerLite offers the most well-rounded free tier in email marketing — and it's not close. While competitors strip features from their free plans to push upgrades, MailerLite includes automation, landing pages, pop-up forms, A/B testing, and a drag-and-drop editor on the free tier. The 1,000-subscriber limit is the only real constraint.

The automation capability on free is the key differentiator. You can build welcome sequences, trigger emails based on subscriber behavior, and create branching workflows — features that Mailchimp, Kit, and most others gate behind paid plans. For a small business or creator starting email marketing, this means you can set up a proper nurture sequence from day one without paying anything.

The editor is clean and modern, with responsive templates that look good on mobile without manual tweaking. The reporting dashboard shows opens, clicks, and subscriber growth trends. Integration with Shopify, WordPress, and Zapier works on the free tier too. When you eventually outgrow 1,000 subscribers, paid plans start at just $10/month — one of the most affordable upgrade paths available.

Brevo (formerly Sendinblue) flips the typical email marketing pricing model. Instead of charging per subscriber, Brevo charges per email sent. The free tier includes unlimited contacts with 300 emails per day (about 9,000/month). For businesses with large contact lists but moderate sending frequency, this is significantly more generous than per-subscriber pricing.

The practical impact: you can import your entire contact list of 5,000, 10,000, or even 50,000 contacts on the free tier. You're only limited by how many emails you can send per day. If you send a weekly newsletter to 2,000 subscribers and occasional automated emails, the free tier covers you completely. On MailerLite or Mailchimp, that 2,000-subscriber list would already require a paid plan.

Beyond email, Brevo includes SMS marketing, WhatsApp campaigns, and a basic CRM on the free tier — making it more of a multichannel marketing platform than a pure email tool. The automation builder works on free for basic workflows (welcome emails, simple triggers). The trade-off is that the email editor and template library aren't as polished as MailerLite's, and the 300 daily send limit means you can't blast your entire list in one shot if it's large.

Kit (formerly ConvertKit) offers the highest subscriber limit of any commercial free tier: 10,000 subscribers. For creators — writers, podcasters, course creators, YouTubers — who are building an audience from scratch, this generous limit means you can grow for years before needing to pay.

The catch is that the free tier is limited to email broadcasts (one-time sends) and basic subscriber management. Automation sequences, visual automation builder, and advanced segmentation require the Creator plan at $29/month. This means Kit's free tier works for newsletters but not for sophisticated drip campaigns or behavior-triggered emails.

Despite the feature limitations, Kit's subscriber-centric approach is well-suited to creators. The tagging and segmentation system (available on free) lets you organize subscribers by interest, and the landing page builder creates simple opt-in pages without needing a website. The plain-text email style that Kit promotes (minimal design, conversational tone) tends to perform well in personal brand contexts. For creators who primarily need to send a regular newsletter and grow their list, 10,000 free subscribers is hard to argue with.

listmonk is the nuclear option for email marketing costs: a self-hosted, open-source platform with absolutely no limits on subscribers, emails, lists, or features. It's completely free — not freemium, not open-core, just free. Your only cost is the server it runs on (typically $5-20/month for a VPS).

For technical teams and businesses with large lists, the economics are compelling. A business sending 100,000 emails/month to 20,000 subscribers would pay $150-300/month on commercial platforms. With listmonk on a $10/month server connected to Amazon SES ($0.10 per 1,000 emails), the same volume costs about $20/month total.

The platform includes everything you need: subscriber management with custom attributes, multiple mailing lists, a template engine with a visual editor, campaign scheduling, analytics with open/click tracking, automated transactional emails via API, and import/export tools. The interface is clean and functional — not as polished as MailerLite's, but perfectly usable. Written in Go, it's extremely performant and can handle millions of subscribers on modest hardware. The trade-off is clear: you manage the infrastructure, deliverability, and updates yourself.

Mailchimp remains the most recognized name in email marketing, and its free tier — while less generous than it used to be — still serves as a solid starting point. The free plan includes 500 contacts, 1,000 monthly sends (with a daily limit of 500), the drag-and-drop email builder, basic templates, and simple reporting.

The honest reality: Mailchimp's free tier has been progressively stripped down over the years. Automation was removed from free plans, the subscriber limit dropped from 2,000 to 500, and features that were once included now require paid upgrades. It's still on this list because the platform itself is excellent, the brand recognition means extensive third-party resources (tutorials, templates, integrations), and for very small operations, 500 contacts is enough to start.

Where Mailchimp still shines on free is the ecosystem. Nearly every SaaS tool, e-commerce platform, and CRM integrates with Mailchimp natively. The email editor is one of the best in the industry — intuitive, flexible, and produces consistently good-looking emails. The content optimizer uses AI to suggest improvements. If you're choosing an email platform you might use for years, Mailchimp's depth becomes more apparent as your needs grow, even though the free starting point is tighter than competitors.

beehiiv is purpose-built for newsletter operators who want to build a media business, not just send marketing emails. The free tier includes up to 2,500 subscribers, unlimited sends, a custom website, and — critically — built-in monetization tools including a referral program, recommendation network, and ad placement capabilities.

The newsletter-first approach means the writing and publishing experience is optimized differently from traditional email marketing platforms. The editor feels more like a blogging platform than an email builder. Your newsletter gets its own website with an archive of past issues, SEO-optimized pages, and a subscriber growth widget. This web presence is something most email platforms don't provide at all, let alone for free.

The monetization features set beehiiv apart for creators who see their newsletter as a business. The Boost network lets you earn money by recommending other newsletters to your subscribers (and vice versa). The referral program incentivizes subscribers to share your newsletter with milestone-based rewards. These features work on the free tier, meaning you can start earning before you pay for the platform. The trade-off is that beehiiv is designed for newsletters, not for e-commerce email marketing, drip campaigns, or complex automation workflows.

Keila is the simpler alternative to listmonk for teams who want self-hosted email marketing without the complexity. Built with Elixir for reliability and performance, Keila offers a clean web interface for managing contacts, creating campaigns, and tracking results — all running on your own server.

The setup is notably easier than listmonk. A Docker Compose deployment gets you running in minutes with PostgreSQL for data storage. The interface includes a visual email editor (not just HTML templates), contact management with custom fields and segmentation, campaign scheduling, and basic analytics. For small-to-medium operations that want self-hosted email marketing without becoming infrastructure experts, Keila hits the right balance.

Keila supports multiple senders (useful for agencies or multi-brand operations), provides GDPR-compliant contact management with double opt-in and data export, and integrates with standard SMTP services (Amazon SES, Mailgun, Postmark) for sending. The open-source license (AGPLv3) means you can inspect, modify, and extend the platform. Like listmonk, there are no subscriber limits, no email caps, and no premium features hidden behind a paywall.
