The best free email marketing in 2026

A free email plan is only free until you hit its ceiling - a subscriber cap, a monthly send limit, or the automation you need three months in. These are the four email platforms we track with a real free plan, with what each free tier actually covers and what the first paid step costs, read from the vendors' own pricing pages this week.

Prices last re-checked 2026-10-04. Numbers are read from each vendor's own pricing page; any exception is flagged under "What to watch".

The short answer

Short answer: Best free email marketing for most small businesses: Kit (formerly ConvertKit) Kit Free is $0/mo for up to 10,000 subscribers, with unlimited landing pages and forms, unlimited broadcasts, tagging and segmentation, and digital product sales - the largest free list cap here by a wide margin.

Best free email marketing for most small businesses: Kit (formerly ConvertKit)

Kit Free is $0/mo for up to 10,000 subscribers, with unlimited landing pages and forms, unlimited broadcasts, tagging and segmentation, and digital product sales - the largest free list cap here by a wide margin. The trade-off: visual automations are not on the free plan - the first paid step is Creator at $39/mo, or $32.5/mo billed annually.

See Kit (formerly ConvertKit) pricing

Best free plan if you need funnels and a course too: Systeme.io

Systeme.io Free is $0/mo for 2,000 contacts, 3 sales funnels, 1 course and unlimited emails - the only free plan here that also runs sales funnels and a course. The trade-off: the contact cap is 2,000, five times lower than Kit's, and the first paid step is Startup at $17/mo, or $14/mo billed annually.

Best free newsletter platform for a publication: beehiiv

beehiiv Free is $0/mo for up to 2,500 subscribers with unlimited sends, 3 publications and 1 team seat - built for newsletters rather than marketing sequences. The trade-off: one team seat and a 2,500-subscriber ceiling; the first paid step is Lite at $59/mo, or $49/mo billed yearly.

Best first paid step when the free plan runs out: MailerLite

MailerLite Comfort is $12/mo, or $10.8/mo billed annually - the lowest entry paid price of the four. It starts at 250 subscribers with 3 user seats, 50 automations and 10 websites and landing pages. The trade-off: MailerLite's own free plan is the tightest here at 250 subscribers and 2,500 emails a month.

Kit (formerly ConvertKit)

Kit is free up to 10,000 subscribers on the Newsletter plan. At 1,000 subscribers Creator is $39/mo billed monthly or $390/yr and Pro is $79/mo or $790/yr. Yearly billing also prints an extra 25% off Pro for the first year only: $50/mo, $593 billed, then it renews at the standard rate. Both plans scale with list size (Creator $169/mo at 15,000, Pro $249/mo).

PlanPriceWhat you get
Free (Newsletter)$0/moUp to 10,000 subscribers, unlimited landing pages and forms, unlimited broadcasts, tagging and segmentation, sell digital products
Creator$39/mo, or $32.5/mo billed annuallyEverything in Free plus unlimited visual automations, unlimited sequences, A/B subject lines, SMS, remove Kit branding
Pro$79/mo, or $65.83/mo billed annuallyEverything in Creator plus Subscriber Signals, engagement analytics, unlimited users, deliverability reporting, newsletter referral system. Yearly billing at 1,000 subscribers prints an extra 25% off the first year ($50/mo, $593 billed). The page says that discount is the first year only and the plan then renews at the standard rate.

What to watch: Free / Creator / Pro were read from kit.com/pricing itself, at 1,000 email subscribers, on 2026-10-12. The monthly toggle prints Creator $39/mo and Pro $79. The yearly toggle prints Creator as $33/mo ($390 billed yearly); that $33 is the page's rounding of $390/12, so the table keeps $32.50. The same yearly view prints an extra 25% off Pro for the first year ($50/mo, $593 billed) with $66 struck through, and says the plan renews at the standard rate after that year. The card does not print the standard Pro yearly total of $790. Kit's paid plans scale with list size, so the price shown is the price at 1,000 subscribers, not a flat rate. Both paid plans say the trial is 14 days and that no credit card is required.

What to watch: Monthly rates $17, $47, and $97 were read on systeme.io/pricing on 2026-10-13, in the page's own FAQ. That FAQ prints Webinar as 50 funnels and 20 courses, Unlimited as unlimited courses and automation rules, and every plan as unlimited email sends, unlimited sub-accounts, and 0% transaction fees. The free plan never expires and does not require a credit card. The same FAQ lists extra free-plan caps of 1 blog, 1 affiliate program, 1 custom domain, 1 automation rule, 1 email campaign, and 500 students.

beehiiv

beehiiv is free up to 2,500 subscribers. At 1,000 subscribers Lite is $59/mo ($49/mo billed yearly) and Pro is $109/mo ($95/mo billed yearly). At 10,000 subscribers Lite is $139/mo ($119/mo billed yearly) and Pro is $239/mo ($199/mo billed yearly). Lite is not sold above 100,000 subscribers. The pricing-page FAQ says Lite and Pro include a free trial, no credit card is needed to start, and the trial ends when you upgrade. That answer does not say how many days the trial lasts.

PlanPriceWhat you get
Free$0/mo (no annual discount published)Up to 2,500 subscribers, 1 team seat, 1 publication, 30-day analytics lookback, unlimited email sends

Enterprisecustom quoteCustom pricing and subscriber volume, SSO/SAML, dedicated IPs, concierge onboarding

What to watch: beehiiv does not publish a price for a subscriber count between the slider stops, so those in-between prices are not on this page. Every stop that is listed was read from beehiiv.com/pricing on 2026-10-10. The plan prices in the first table are the 1,000-subscriber stop. Lite is not sold above 100,000 subscribers. Yearly figures are the per-month price when you pay yearly. On 2026-10-12 the yearly cards in the page HTML still showed Lite at $49/mo and Pro at $95/mo at 1,000 subscribers. The monthly toggle is not in that HTML, so those monthly rates stay the 2026-10-10 reading. On that same read, the Pro card carried beehiiv's own Most Popular badge. This page does not treat that badge as a count of customers. The FAQ says the Lite and Pro trial ends when you upgrade, and it does not say how many days that trial lasts. The page HTML does not contain a 14-day trial.

Mailchimp, Brevo and Constant Contact: what they cost

Every email-marketing comparison starts with these three names, so here is what each one actually charges. Every price below was read on the vendor's own pricing page and is re-checked weekly - the link goes to the full plan tables and the fine print:

Cheaper first paid month: Brevo Starter at $9/mo is below the cheapest paid step among the picks above (MailerLite Comfort at $12/mo). Those entry prices are for the smallest list or send volume each vendor sells, so price them at your own size before you switch.

Compare these numbers against the picks above at your own list size: the cheapest tool for a 500-contact shop is rarely the cheapest at 10,000 subscribers, and the free tiers stop at very different places.

Questions people ask

What is the cheapest option here?

Kit is the cheapest option here to start - Kit Free is $0/mo for up to 10,000 subscribers. Systeme.io Free is also $0/mo but caps at 2,000 contacts, and MailerLite Free is $0/mo for 250 subscribers and 2,500 emails a month. When you start paying, MailerLite Comfort is the lowest step up at $12/mo, or $10.8/mo billed annually.

Is a free email plan really free?

Yes - the four free plans cost $0/mo. The limits are what you pay with: Kit Free caps at 10,000 subscribers, Systeme.io Free at 2,000 contacts, beehiiv Free at 2,500 subscribers, and MailerLite Free at 250 subscribers and 2,500 emails a month.

What happens when the free plan runs out?

The first paid steps are MailerLite Comfort at $12/mo, or $10.8/mo billed annually, Systeme.io Startup at $17/mo, or $14/mo billed annually, Kit Creator at $39/mo, or $32.5/mo billed annually, and beehiiv Lite at $59/mo, or $49/mo billed yearly.

Which free plan is best for a newsletter?

For a newsletter, beehiiv Free is the newsletter-first option at $0/mo for up to 2,500 subscribers with unlimited sends, but Kit Free covers up to 10,000 subscribers with unlimited broadcasts and forms, so Kit is the better free newsletter list until 10,000 subscribers.

How often are these prices re-checked?

Every week. The prices on this page - Kit Free at $0/mo, MailerLite Comfort at $12/mo and the rest - are read from the vendors' own pricing pages and re-checked weekly; the date under the title is the oldest check behind this page. A number we can no longer find on the vendor page is flagged and keeps its previous check date instead of claiming a fresh one.

Some links on this page are affiliate links. If you buy through one we may earn a commission at no extra cost to you. We do not accept payment for placement, and the price tables are generated from the same dataset we re-check weekly. Full disclosure. How we check prices.
