Mailchimp and Kit (the platform formerly known as ConvertKit, rebranded in late 2024) are the two email tools freelancers researching newsletter software compare most often, and the honest framing — echoed consistently across independent 2026 comparisons — is that they're built for different jobs: Kit for creators and audience-led businesses, Mailchimp for broader small-business marketing. One specific billing detail matters more than most feature comparisons here.
Coming from a consulting background, I default to evaluating pricing structure and long-term cost before comparing features line by line.
The billing detail that changes the real cost
Mailchimp counts every contact in your audience against your plan limit — including unsubscribed addresses. Kit only bills for active subscribers. If a meaningful share of your list has unsubscribed over time (common for any list that's been running a while), Kit's effective cost can end up significantly lower than a sticker-price comparison at the same subscriber count would suggest, even before comparing free-tier limits directly.
Quick comparison
| Kit (ConvertKit) | Mailchimp | |
|---|---|---|
| Free plan limit | Up to 10,000 subscribers | 250 contacts |
| Billing basis | Active subscribers only | All contacts, including unsubscribed |
| Built-in commerce | Yes — sell digital products directly, 3.5% + $0.30 per sale on paid plans | Via integrations, less native |
| Design flexibility | More opinionated, simpler | Hundreds of templates, mature drag-and-drop editor |
| Integrations | Fewer, creator-focused | 300+ |
| Starting paid price | Creator plan ~$39/month (at 1,000 subscribers) | Essentials ~$26.50/month (at 1,000 subscribers) |
Where Kit wins
Kit's free plan is one of the most generous in the category — up to 10,000 subscribers with unlimited sends and only active-subscriber billing, which is a genuinely different value proposition than Mailchimp's 250-contact free cap. Its built-in commerce features let you sell digital products, courses, or templates directly without a separate platform like Gumroad, and its automation is built around tags and subscriber behavior in a way multiple reviews describe as cleaner and less cluttered than Mailchimp's broader, more general-purpose automation builder. For a freelancer specifically building an audience with the intent to eventually monetize it — a paid newsletter, a course, digital products — Kit's whole product is shaped around that path.
Where Mailchimp wins
Mailchimp's design flexibility is a real, consistent advantage — a much larger template library and a more mature drag-and-drop editor than Kit's more opinionated, simpler interface. Its 300+ integrations dwarf Kit's smaller, creator-focused set, which matters if email is one piece of a broader marketing stack involving e-commerce, CRM, or social tools. At smaller list sizes specifically (1,000 subscribers), Mailchimp's Essentials plan is also cheaper than Kit's equivalent Creator tier on paper — though that comparison shifts once Kit's active-subscriber-only billing and larger free tier are factored in.
A pricing change worth knowing
Kit's paid tiers increased meaningfully in September 2026, which is worth checking against current published pricing rather than assuming older comparisons (including parts of this one) reflect today's exact numbers — this is a genuinely fast-moving pricing category on both platforms.
Bottom line
For freelancers building an audience with the goal of eventually selling something directly to that list — a course, digital products, paid subscriptions — Kit's creator-first design, generous free tier, and active-subscriber billing make it the more natural fit, and it's the platform this site generally points to in our newsletter tools guide. For freelancers who want stronger visual design tools, a much larger integration ecosystem, or are already running broader small-business marketing beyond just a newsletter, Mailchimp remains the safer, more mainstream choice.
Pricing, free-tier limits, and billing structures for both platforms change frequently — Kit's September 2026 increase is one recent example. Confirm current details directly on each provider's site before choosing.
