Kit vs MailerLite: 10,000 Free Subscribers, Limited Automation

Kit is the better choice for a creator who sends newsletters manually and wants room to grow without a subscription bill. Kit’s Free plan terms allow up to 10,000 subscribers and unlimited broadcasts, while visual automations and email sequences require a paid plan.

MailerLite becomes the better value when a welcome series, branching follow-ups or visual layouts are central to the newsletter. MailerLite’s plan comparison gives Free accounts up to 250 subscribers, 2,500 monthly emails and three active automations; paid plans expand those controls. Its smaller free audience makes the workflow, rather than list capacity alone, the deciding factor.

What the list costs at five sizes

These are US dollar subscription prices for monthly billing, before tax or selling costs. AutoMarketer’s Kit pricing ladder puts Creator at $39 for up to 1,000 subscribers, $89 at 5,000, $139 at 10,000 and $199 at 25,000. SideBySend’s September 2026 MailerLite price snapshot records the Comfort and Power rates at the same list sizes and at 500 subscribers. The plans are shown together to expose the price of adding automation to Kit, not to suggest their features are identical.

500 subscribers: Kit Free $0 or Creator $39; MailerLite Comfort $12 or Power $25 per month.
1,000 subscribers: Kit Free $0 or Creator $39; MailerLite Comfort $19 or Power $39 per month.
5,000 subscribers: Kit Free $0 or Creator $89; MailerLite Comfort $49 or Power $69 per month.
10,000 subscribers: Kit Free $0 or Creator $139; MailerLite Comfort $89 or Power $129 per month.
25,000 subscribers: Kit Creator $199; MailerLite Comfort $179 or Power $239 per month. Kit Free cannot hold a list this large.

For a broadcast-only newsletter within Kit’s free ceiling, the subscription saving is straightforward. Once automated sequences make Kit Creator necessary, MailerLite Comfort has a lower listed monthly charge at every size shown. At 10,000 subscribers, that difference is $50 a month, or $600 across twelve months at unchanged rates. Power changes the comparison: at 25,000 subscribers it costs more than Kit Creator, so a sender who needs Power’s allowances should compare those plans directly.

The automation limit arrives before the subscriber limit

Kit Free can tag and segment an audience, collect signups through forms and landing pages, and sell digital products. Those capabilities still leave a gap for a creator whose signup must start a timed welcome series or whose purchase must trigger follow-up emails. Kit Creator adds unlimited visual automations and email sequences, making the first required automated journey a possible upgrade point well before the list reaches the free ceiling.

MailerLite Free permits three active automations with up to five steps each. Comfort raises the allowance to 50 active automations with up to 100 steps per workflow, while Power allows unlimited active automations and multiple triggers for a workflow. A small creator can therefore build a short welcome flow without paying MailerLite, although the free subscriber and sending ceilings may prompt an upgrade sooner than the automation allowance does. Comfort suits a larger list with several flows; Power matters when those limits or its extra trigger controls become necessary.

Sending frequency creates another crossover. Comfort includes monthly sends equal to ten times the ceiling of its subscriber tier, while Power offers unlimited sends subject to fair use. In a hypothetical month, four issues sent to every member of a 10,000-person list use 40,000 sends before automation emails, within Comfort’s 100,000-send allowance at that tier. A daily issue to that full list would pass the allowance. Kit’s unlimited broadcasts avoid that particular calculation, although its paid subscription still rises with list size.

Design, recommendations and product sales

The editors favor different kinds of publication. SendPulse’s hands-on comparison describes Kit as a focused writing canvas and MailerLite as a more flexible block-based editor with greater layout control; it also finds broader actions and branching in MailerLite’s automation builder. That makes MailerLite attractive for newsletters built around arranged sections, images and distinct campaign layouts. Kit’s simpler composition flow can suit a text-led issue that is written and sent with few design decisions.

Kit also gives creators an audience-growth option through its Creator Network. Free accounts are enrolled when they sign up, but recommendations can be turned off without losing the free plan. A creator who uses referrals and sells a digital product alongside manually sent issues may get substantial use from Kit before paying for automation.

MailerLite supports digital products, bookings and paid newsletters as well. Its Free plan allows one digital product or booking, Comfort allows five, and Power removes that product limit. For a seller, the relevant comparison is therefore the number of offers and the emails each sale should start, alongside any checkout charges. A lower email subscription price does not by itself describe the cost or fit of the complete selling workflow.

Support, billing and the cost of moving

Support differs at the free level: Kit Free requests are answered within 24 hours, while MailerLite Free provides community support. Kit Creator includes email and chat support; MailerLite Comfort includes email support, and Power adds live chat. A launch that depends on prompt direct help may make that difference more consequential than a small gap between paid subscriptions.

Both platforms count active subscribers, but MailerLite uses a cumulative count within each billing cycle. An address that was active during the cycle remains in that cycle’s count even if it is deleted before renewal. Crossing a paid subscriber tier automatically increases the tier and charge; crossing the Free limit pauses campaigns and automations until the count falls or the account is upgraded. Kit counts unique active subscribers and requires a paid upgrade to keep sending after its Free limit. These rules can move the actual bill away from a comparison made at a neat list-size breakpoint.

Switching platforms also means rebuilding the journeys behind the list. Kit tags and sequences need to be mapped to MailerLite groups, segments and automations, or the equivalent structure in the other direction; signup forms, purchase follow-ups and email layouts need attention too. Preserve consent and suppression status during an import, then test the signup and sale paths before replacing live forms. Kit Free is the clear subscription bargain for a mostly manual newsletter; MailerLite Comfort is the stronger paid value when visual campaigns and recurring automated journeys are already part of the publication.
