Kit vs MailerLite (2026): Free Plans, Pricing and Which to Choose

Disclosure: Fin Ventures AI is applying to the Kit and MailerLite affiliate programs. If you sign up through our links we may earn a commission, at no cost to you. Limits and prices come from kit.com/pricing and mailerlite.com/pricing, re-read on November 5, 2026. For details we could not confirm here, check the official site for current details.

The short answer

• Pick Kit if you are a creator who expects to grow past a few hundred subscribers and wants to stay free as long as possible: Kit’s free plan goes up to 10,000 subscribers with unlimited sends.
• Pick MailerLite if your list will stay small for a while and you want a broad toolset on free — website, landing page, three automations, three editors — or a low first paid step (Comfort from $12/month).

At a glance

Free plans in depth

Kit free

Kit’s pricing FAQ describes the free plan as “perfect if you’re focused on building your audience”, with “essential tools to build and engage an audience of up to 10,000 subscribers, for free”. The same FAQ states: “There are no sending limits on any of our plans.”

What the official page does not let us confirm today: exactly which automations, integrations and landing-page features are restricted on free. Kit’s paid plans add, among other things listed on the page for Pro, subscriber engagement scoring, deliverability reporting, a newsletter referral system and the ability to edit links in sent broadcasts.

MailerLite free

MailerLite is unusually explicit about its free plan. Per mailerlite.com/pricing:

• 250 subscribers, 2,500 monthly emails;
• campaigns, free automations (3 active, up to 5 steps), 1 website and 1 landing page, 3 active forms;
• all three editors: drag & drop, custom HTML and simple;
• 2 user seats;
• 100+ integrations; API and MCP access are limited on free and don’t include sending.

The critical rule: “For free accounts, when the number of active subscribers exceeds the 250 active subscriber limit, sendings will be locked (campaigns + automation).” Plan your upgrade before you reach 250.

Paid plans

MailerLite

MailerLite now prices by usage, not by feature: “Every paid plan gets our full feature set. You only pay more for a bigger list or more sending.”

• Comfort, from $12/month: everything in Free plus unlimited templates, dynamic emails, auto-resend, multivariate testing, unsubscribe page builder, preference center, AI writing assistant, smart sending; 50 automations, 10 forms, 10 sites, 3 seats. Monthly sends = 10× the top of your subscriber tier.
• Power, from $25/month: unlimited sends (fair use), unlimited automations, forms, sites, seats, multiple automation triggers, 24/7 live chat.
• Enterprise: custom, for 200K+ subscribers.

Annual billing saves 10%.

Kit

Kit lists Creator and Pro plans. Our internal research recorded Creator at $39/month as a reference price; we could not confirm today’s per-tier price from the page (pricing is shown by list size), so treat exact figures as check the official site for current details and check kit.com/pricing for your subscriber count. Kit notes that the Pro first-year discount applies only to year one.

Feature philosophy

Kit is built around creators: tags rather than lists, visual automations, a creator network and, on Pro, a newsletter referral system. Its marketing is aimed at authors, YouTubers and newsletter writers; the page cites 550,000+ creator businesses.

MailerLite is built around a broad, simple toolset for small businesses and creators: an editor many beginners find easy, websites and landing pages, digital products and bookings, surveys and quizzes on paid plans. It cites 1M+ creators and businesses.

Both claims are the vendors’ own statements.

Cost scenarios (list prices)

The pattern is clear even without exact tier prices: between 250 and 10,000 subscribers, Kit costs $0 and MailerLite does not. The trade-off is that MailerLite’s free plan documents more included tooling, and its paid entry point is low.

Affiliate terms (for creators who also want to recommend the tool)

If you plan to promote the tool you use, the affiliate terms matter:

• Kit: 50% of payments for the first 12 months, plus 10% lifetime if you refer at least 10 paying customers a year (kit.com/affiliate, verified in our November 5, 2026 audit).
• MailerLite: 30% recurring for life, 45-day cookie, payouts from $100 after 2+ unique sales, with a possible hold of up to 180 days during an investigation (MailerLite affiliate terms, verified in the same audit).

Neither should decide which tool you use for your own list, but it’s useful context for affiliate marketers.

Which should you choose? Five profiles

1. New YouTuber or newsletter writer, no budget: Kit. The 10,000-subscriber free ceiling gives you months or years of runway.
2. Local business with a small, stable list: MailerLite free, then Comfort. You’ll value the website and landing page.
3. Coach selling digital products and bookings: MailerLite’s digital products and bookings are documented on its plans; Kit’s commerce features are check the official site for current details. Test both.
4. Team of three or more: MailerLite Comfort includes 3 seats; Power unlimited. Kit’s seat limits per plan are check the official site for current details (Pro lists unlimited users).
5. Anyone who needs funnels and a course too: neither is the best fit; look at Systeme.io, which bundles email, funnels and courses with a free plan.

A 30-day test you can run yourself

If you’re still undecided, both tools can be tested at $0, so let your own data decide:

1. Days 1–2: open a free account on each. Import nothing yet.
2. Days 3–5: build the same signup form and the same three-email welcome sequence in both. Time yourself. The tool you finish faster in is the one you’ll actually keep using.
3. Days 6–7: send the test sequence to two or three of your own addresses on different providers (Gmail, Outlook, a work address). Note where each email lands. This is not a deliverability study, but it catches obvious setup problems such as a missing domain authentication.
4. Days 8–30: run real signups through one tool only (splitting a tiny audience produces meaningless numbers). Track signup rate, first-email open rate and clicks.
5. Day 30: decide. If you’re likely to cross 250 subscribers within a few months and don’t want to pay, Kit’s free ceiling probably settles it. If MailerLite’s editor and site saved you hours, its Comfort plan may be worth the price.

Whatever you choose, keep a CSV export of your list every month. It’s free insurance against any account problem.

Migration between the two

Kit offers free migration on paid plans. MailerLite offers a migration page and a success team for larger lists. Both let you export subscribers. When moving, re-confirm consent records and keep your unsubscribed contacts suppressed.

Compliance reminder

Both tools add unsubscribe links. You remain responsible under CASL (Canada) and CAN-SPAM (US) for consent, sender identification and your postal address in the footer.

How we evaluated

We re-read kit.com/pricing and mailerlite.com/pricing on November 5, 2026, and the affiliate terms of both programs in our audit the same day. We list only what those pages state. We did not test deliverability or editors hands-on for this article.

FAQ

Is Kit really free up to 10,000 subscribers? That’s what Kit’s official pricing FAQ states, with no sending limits on any plan.

Why does MailerLite only allow 250 free subscribers? That’s its current free-plan limit; above it, sending is locked on free accounts until you upgrade.

Which is cheaper? Between 250 and 10,000 subscribers, Kit, because it’s free. Below 250 both are free. Above that, compare the tier prices for your exact list size on each pricing page.

Which has better automations? On free, MailerLite documents 3 active automations; Kit’s free automation limits are check the official site for current details. On paid plans both offer visual automation builders.

Bottom line

Kit wins on free-plan headroom; MailerLite wins on documented free tooling and a low first paid step. Pick the one whose limit you’ll hit last.
