Free Email Marketing Tools: What You Actually Get in 2026

The Real Free Plans (Not Trials)

Let us be clear about what free means here. We are only covering plans that are genuinely free indefinitely — not 14-day trials, not 30-day trials, not money-back guarantees. If it requires a credit card and eventually starts charging, it is not free.

Surprisingly few email marketing tools offer a truly free ongoing plan. Many platforms that used to have generous free tiers have either eliminated them or cut them dramatically. Mailchimp reduced their free plan from 2,000 to just 250 contacts. Several tools that advertised free plans now only offer free trials.

As of early 2026, the platforms with genuine free-forever plans are: MailerLite, Brevo, Mailchimp, Klaviyo, beehiiv, and Kit (formerly ConvertKit). Each has very different limits and trade-offs, and some are far more usable than others.

The question is not just whether you can start for free — it is whether the free plan is functional enough to run a real email marketing operation while you grow, or whether it is so limited that it is essentially a demo.

MailerLite Free: 500 Subscribers, 12,000 Emails

MailerLite's free plan supports up to 500 subscribers (reduced from 1,000 in September 2025) and 12,000 email sends per month. That is enough for a weekly newsletter to a small list with room to spare for automated sequences.

What you get: the drag-and-drop email editor, a website builder, landing pages and signup forms, basic automation workflows (including the visual builder), and email support for the first 30 days (then knowledge base only). You also get 10 landing pages and basic reporting.

What you do not get: pre-designed email templates (you build from scratch or use the rich text editor), the auto-resend to non-openers feature, A/B testing for automations, the ability to sell digital products, dynamic content, and priority support.

The MailerLite branding appears on your emails on the free plan — a small "Sent with MailerLite" badge in the footer. Some users find this unprofessional, but it is standard practice for free email tools.

The approval process is the biggest hurdle. MailerLite manually reviews every new account, and they are known for rejecting or suspending accounts they deem high-risk. You need a functioning website with clear purpose, a legitimate subscriber acquisition method, and content that does not fall into their restricted categories (gambling, dating, finance, and certain health niches). If you get rejected, you may not get a clear explanation.

Our take: MailerLite Free is the most capable free email marketing plan available. The automation, landing pages, and 12,000-email allowance make it genuinely possible to run a small email operation without paying anything. The lack of templates is a minor inconvenience — their editor is intuitive enough to build clean emails without them.

Brevo Free: Unlimited Contacts, 300 Emails/Day

Brevo's free plan takes a completely different approach. Instead of limiting your subscriber count, they limit your daily sends. You can have as many contacts as you want, but you can only send 300 emails per day — roughly 9,000 per month.

What you get: unlimited contacts, the drag-and-drop editor, automation workflows, transactional email API, SMS marketing (pay-per-message), and basic reporting. No branding limitations — Brevo branding appears in the footer, but it is subtle.

What you do not get: A/B testing, send time optimization, landing pages, advanced statistics, phone support, or the ability to remove Brevo branding.

The 300-per-day limit is the critical constraint. If you have 1,000 subscribers and send one campaign, that campaign goes out over 3-4 days instead of all at once. For time-sensitive content (sales, launches, events), this is a dealbreaker. For regular newsletters, it is workable.

Brevo's transactional email inclusion is a genuine differentiator on the free plan. If you run a website or app that sends order confirmations, password resets, or similar automated messages, Brevo lets you handle both marketing and transactional email from one platform at no cost.

Our take: Brevo Free is best for businesses with a large existing list but low sending frequency. If you have 5,000 contacts but only email once a week, the 300/day limit is irrelevant — your weekly campaign sends over 2-3 days, and most subscribers will not notice. For small lists sending frequently, MailerLite is a better option.

Mailchimp Free: 250 Contacts, 500 Emails

Mailchimp was once the gold standard for free email marketing. Their free plan used to include 2,000 contacts and 10,000 emails per month. Those days are over.

As of 2026, Mailchimp Free gives you 250 contacts and 500 emails per month. That is enough for about 2 emails per month to your full list, or one weekly email to a 125-subscriber list. For most businesses, this is not enough to build on.

What you get: basic email campaigns with the drag-and-drop builder, one audience (list), basic reporting, and Mailchimp's extensive template library. You also get Mailchimp's integrations ecosystem, which is the most extensive in the industry.

What you do not get: automation (beyond a single welcome email), A/B testing, custom branding (Mailchimp badge appears prominently), scheduled sending (campaigns send immediately), email support (chat only for first 30 days, then nothing), and advanced segmentation. The reporting on the free plan was also reduced — you get 30 days of email performance data instead of full historical reporting.

The contact counting is the kicker. Mailchimp counts unsubscribed and non-subscribed contacts toward your 250 limit. If someone signs up, then unsubscribes, they still count unless you manually archive them. At 250 contacts, even a handful of unsubscribes can push you toward the limit.

Our take: Mailchimp Free is no longer competitive. The 250-contact limit is too restrictive, the feature set is too stripped down, and the contact counting policy adds insult to injury. Mailchimp is still a solid platform on paid plans, but their free tier is now a poor choice for anyone serious about email marketing.

Klaviyo Free: 250 Contacts, 500 Emails

Klaviyo's free plan is the most limited in terms of contacts but gives you access to the full Klaviyo feature set at a tiny scale.

What you get: 250 active contacts, 500 email sends per month, and access to all of Klaviyo's features — including their advanced segmentation, behavioral flows, product recommendations, and revenue attribution. Email support for the first 60 days. You also get 150 free SMS credits per month.

What you do not get: anything beyond 250 contacts. Once you exceed that, your first paid tier is $20/month for 251-500 contacts, scaling to roughly $30/month at 1,000 contacts.

The value proposition is clear: Klaviyo's free plan is a demo of an enterprise-grade e-commerce email platform. If you run a Shopify or WooCommerce store and want to test whether Klaviyo's behavioral automation generates enough revenue to justify the cost, the free plan lets you prove the concept.

For general email marketing — newsletters, content, B2B communications — Klaviyo Free makes no sense. The 250-contact limit means you will hit the paywall almost immediately, and you will be paying a premium for e-commerce features you do not need.

Our take: Klaviyo Free is useful exclusively for small e-commerce stores testing the platform. For every other use case, the contact limit is too restrictive. If you are an e-commerce brand with under 250 subscribers, absolutely try Klaviyo Free — the revenue attribution data alone may convince you to stay.

Other Free Options: beehiiv and Kit

beehiiv and Kit are not traditional email marketing platforms, but they both offer free plans worth considering if they fit your use case.

beehiiv Launch (Free): up to 2,500 subscribers with unlimited emails. This is the most generous subscriber limit among all free plans. You get a newsletter editor, hosted website, basic analytics, and access to beehiiv's recommendation network (where newsletters promote each other). No automation, no advanced segmentation, and beehiiv branding appears on your newsletter.

The catch: beehiiv is a newsletter platform, not a full email marketing tool. There are no automation workflows, no e-commerce integrations, no landing page builder (beyond the newsletter signup page), and limited segmentation. If you are a writer, journalist, or content creator whose primary channel is a newsletter, beehiiv Free is excellent. If you need traditional email marketing features, it is the wrong tool.

Kit (formerly ConvertKit) Free: up to 10,000 subscribers. Kit recently introduced a generous free plan that includes landing pages, basic email broadcasts, and subscriber tagging. However, no automation sequences, no visual builder (plain text only on free), and Kit branding is included.

Kit's 10,000-subscriber limit is by far the highest on any free plan. But without automation — which is the core reason most people use email marketing software — the free plan is essentially a list-building and broadcasting tool. You can collect subscribers and send them occasional emails, but you cannot create the drip sequences, welcome flows, or behavioral triggers that drive engagement.

Our take: beehiiv Free is the best free plan for pure newsletter creators. Kit Free is the best for building a large list cheaply and upgrading later when you need automation.

When to Upgrade From Free

Free plans are a launching pad, not a destination. Here are the signals that it is time to start paying.

You are hitting subscriber or send limits regularly. If you are archiving contacts or timing sends to stay under limits, the free plan is costing you more in time and lost engagement than the cheapest paid tier would.

You need automation beyond basics. A welcome sequence is table stakes. If you need abandoned cart flows, behavioral triggers, conditional workflows, or drip sequences, you need a paid plan on most platforms.

You want A/B testing. Free plans rarely include A/B testing, which is one of the highest-ROI features in email marketing. Even basic subject line testing can improve open rates by 10-20% over time.

Branding matters to your audience. If you are sending emails to business clients, investors, or premium customers, the platform branding on free plans looks unprofessional. Paid plans remove it.

You need support. Free plans typically have no live support. When something breaks — and something will break — being stuck with a knowledge base is painful. Even basic email support (included in most $10-20/month plans) saves hours of troubleshooting.

The transition from free to paid does not have to be expensive. MailerLite's Growing Business plan starts at $10/month. Brevo Starter is $9/month. These are not significant costs for any business generating revenue.

Our Pick for Best Free Plan

For most people starting out with email marketing, MailerLite Free is the best choice. The combination of 500 subscribers (it was 1,000 before September 2025, but still the most capable free plan), 12,000 monthly emails, automation, and landing pages gives you everything you need to build and engage a small audience. The deliverability is the best in the industry, which means more of your emails actually reach the inbox. And when you are ready to upgrade, the paid plans are the most affordable in the category.

The second choice depends on your situation. If you already have a large list and need unlimited contacts, Brevo Free is the obvious pick. If you are a newsletter creator, beehiiv Launch gives you the most room to grow. If you are testing e-commerce email for a small shop, Klaviyo Free lets you prove the ROI.

Avoid starting on Mailchimp Free. The 250-contact limit is too restrictive, and once you have invested time building templates and automations on Mailchimp, migrating away is painful. Starting on a more generous free plan saves you a migration headache later.

One final note: do not let free limit your thinking. If your business generates revenue from email — even $100/month — a $10/month email tool is a 10x return on investment. Free is a fine place to start, but the best email marketing investment you can make is choosing the right platform and paying for the features you actually need.
