Kit and Mailchimp: Free Limits and Revenue Fit

Kit is the stronger starting choice for a newsletter earning from its readers. Kit’s published pricing allows up to 10,000 active subscribers and unlimited broadcasts on Free; its advertised $33 monthly Creator rate requires annual billing. Mailchimp’s plan table limits Free to 250 contacts and 500 sends a month. For a store that needs purchase-based campaigns and broader marketing tools, Mailchimp can justify moving to a paid plan sooner.

Revenue alone does not make Kit’s free plan inadequate: it can sell digital products and paid newsletter access while the software subscription remains free. The cost changes when a creator needs an automated welcome sequence. A store faces a different calculation, because a smaller paid audience may be worth more than a larger free one if its campaigns depend on shopping behavior, product presentation and channels beyond email.

What four audience sizes cost

Use monthly billing in US dollars to compare paid plans on the same basis, before taxes, transaction charges and optional add-ons. The EmailTooltester comparison lists Kit Creator at $39 for up to 1,000 subscribers, $89 for 5,000 and $139 for 10,000. The GoodPostal October 2026 price index records Mailchimp’s monthly Essentials and Standard prices at the corresponding contact bands; its quote for 1,000 contacts uses a tier priced from 1,500.

250 people: Either Free plan costs $0 if its features and send allowance fit. Kit Creator costs $39 on monthly billing. Mailchimp Essentials starts at $13 and Standard at $20, both priced from the 500-contact band.
1,000 people: Kit Free remains $0 for broadcasts, or Creator costs $39 for sequences and visual automations. Mailchimp Free no longer fits; Essentials costs $26.50 and Standard $45.
5,000 people: Kit Free remains $0; Creator costs $89. Mailchimp Essentials costs $75 and Standard $100.
10,000 people: Kit Free still costs $0; Creator costs $139. Mailchimp Essentials costs $110 and Standard $135.

The free-versus-paid spread is substantial for a publication sending regular issues without automated onboarding. Once both businesses need paid automation, the gap narrows: at 5,000 people, Mailchimp Essentials is $14 less per month than Kit Creator, while Mailchimp Standard is $11 more. Those are plan-price differences, not savings estimates; the plans support different workflows. Kit’s lower advertised Creator entry rate also commits the buyer to annual billing, so it should not be substituted for $39 in a month-to-month comparison.

Which people count toward the limit?

Kit counts unique, active subscribers in an account and uses tags and segments to organize them. Mailchimp treats separate audiences separately: the same email address in a newsletter audience and a customer audience can count twice toward billing. That distinction matters most near a contact-band boundary. A business with 4,800 distinct people could, for example, occupy a higher billed band if enough of them also appear in a second audience; that is a conditional example, not an estimate of a typical account.

Keeping newsletter readers and buyers in one Mailchimp audience, then separating them with tags or segments, avoids that particular duplicate-count problem. It does not make every stored contact sendable. Unsubscribed people and store contacts who have not opted in can still affect a Mailchimp contact total, while archived and cleaned contacts are excluded. Kit’s free ceiling, by contrast, refers to active, unique subscribers. A price comparison based only on the recipients of the next email can therefore understate what a store will pay to maintain its customer records.

Sending and automation change the comparison

Kit Free suits a publication that writes an issue and sends it to its list: broadcasts are unlimited, and the plan includes forms, landing pages, tagging and segmentation. It does not include the email sequences or visual automation builder needed to send a timed welcome series. Creator adds those tools, so a newsletter can begin earning on Free yet still face an upgrade when onboarding becomes part of its operation.

Mailchimp Free runs into a sending limit even before a list grows. At the full 250-contact allowance, two emails to everyone use its 500 monthly sends; a third full-list issue exceeds the allowance. Essentials raises the monthly send allowance to ten times the plan’s maximum contact count and adds scheduling and marketing automation flows with up to four steps. Standard offers longer, more flexible journeys and additional personalization, making the required journey—not just the number of contacts—the relevant tier decision.

Design and support also change what a paid plan buys. Mailchimp offers more freedom to arrange promotional email layouts, which can matter when product images and offers carry a campaign. Kit’s simpler editor is a closer fit for a text-led publication. Mailchimp Free offers email support only for an initial period, while its paid plans include ongoing email and chat support; Kit lists email and chat support on Creator. A launch that depends on timely help should be priced against those paid tiers.

How each platform helps earn revenue

Kit’s native sales tools fit a publication selling access to its writing, a digital download or a recurring subscription. Those products can be offered on Free, although sales incur transaction fees. Mailchimp can market products from a connected store, but paid newsletter access generally needs a separate selling service. The software subscription price is therefore only one part of the creator’s cost: checkout, fulfillment and the work of connecting tools matter too.

A store gets more from Mailchimp’s wider campaign toolkit. The Zapier comparison finds Kit better aligned with creator monetization and Mailchimp broader for ecommerce and multichannel marketing, including purchase-based promotions and social scheduling. Mailchimp also offers SMS through a paid add-on in eligible markets. These capabilities can connect an email campaign to a sale, though the store integration, plan and customer permissions still determine which messages can run.

Kit can connect to Shopify and run abandoned-checkout sequences on a paid plan, so cart recovery alone does not settle the choice. Its strength is combining that follow-up with a creator’s tagged audience and native digital sales. Mailchimp becomes more compelling when a store wants product-focused campaign design, customer journeys and social activity managed together. A merchant comparing only the two free subscriber limits would miss that operating difference.

Two workflows, scored against their requirements

Consider a hypothetical creator with 5,000 subscribers who needs weekly issues, interest tags, native paid newsletter access and a timed welcome sequence. Counting one point per requirement, Kit Free covers three of four at $0; Creator covers all four at $89 a month. Mailchimp Essentials covers issues, tags and a short welcome flow for $75 a month, but native paid newsletter access requires another service. Its lower paid-plan price does not remove that extra selling step.

Now consider a hypothetical Shopify store with 5,000 contacts that wants a store connection, abandoned-cart follow-up, broad product-promotion layouts and social scheduling. Mailchimp Standard is the stronger fit for all four requirements at the indexed $100 monthly price, subject to the connected store and the exact journey configured. Kit Creator covers the store connection and cart sequence at $89; its narrower design and social-marketing scope make it a weaker fit for the remaining requirements. These are editorial fit scores for the stated needs, not performance-test results or promises of sales.

The choice turns on what produces the revenue. If readers pay for the publication or its digital products, Kit can preserve a large free audience until automated sequences justify Creator. If repeat purchases depend on coordinated store campaigns, Mailchimp’s paid features can outweigh its small free allowance. Price the journey the business will actually run, including the contacts it stores and the messages it sends.
