Mailchimp and ConvertKit (now branded Kit) are usually the first two names a new email marketer hears — which makes this comparison feel like a coin flip between two similar tools. It isn’t. They’re two genuinely different products that happen to share a feature: sending email.

Mailchimp is a general-purpose marketing platform built for small businesses. Kit is a focused email platform built for creators. Most of the frustration people report with either tool comes from picking the one designed for the other audience.

It doesn’t change which tool is right for you, and everything here is my genuine assessment — including where each platform falls short, and where a cheaper option might serve you better.

This comparison walks through where each one wins, the pricing gotchas worth knowing, and which kind of sender each suits — plus an honest note on a free all-in-one if neither quite fits.

The core difference in one sentence

Mailchimp is a marketing suite for a small business — design-led campaigns, templates, landing pages and a broad feature surface for promoting a company. Kit is an audience engine for a creator — tagging, automation sequences, deliverability and direct selling to the people on your list.

The fastest way to choose: finish this sentence — “I’m emailing my ___.” If the blank is customers, you’re probably a Mailchimp user. If the blank is audience or readers, you’re probably a Kit user.

Mailchimp: the small-business all-rounder

Mailchimp (now part of Intuit) is one of the most recognisable names in marketing software, and the product matches the brand: polished, broad and built so a small business can run its marketing from one familiar place.

Pros:

Design-led email. A large template library and a polished editor make it easy to send branded, visual campaigns that look professionally designed — Mailchimp’s traditional strength.
Broad marketing surface. Beyond email you get landing pages, signup forms, audience insights and a wide integration ecosystem, so one account covers a lot of small-business marketing jobs.
Familiar and well-supported. It’s the tool your accountant has heard of. Documentation, integrations and third-party help are everywhere.
A free tier to start. You can begin without paying, though its limits have tightened over the years.

Cons:

Contact-based billing with a housekeeping catch. Mailchimp’s billing has historically been based on contacts stored in your audience — which can include unsubscribed and non-buying contacts depending on settings — so an untidy list quietly inflates the bill.
Key features gated by tier. More advanced automation and segmentation tend to sit on higher plans, which is exactly when a growing list is already raising your price.
Heavier than many people need. The breadth shows up as clutter if all you want is to write and send a newsletter.
Campaign-centric, not audience-centric. Its model grew up around sending designed campaigns to lists — workable for creators, but tag-based, behaviour-driven publishing isn’t its native shape.

Mailchimp suits a small business that markets to customers: designed campaigns, promotions, a brand look, and one familiar tool that also handles pages and forms.

Kit (ConvertKit): the creator specialist

Kit was built around a specific belief: for a creator, the email list is the business. Everything in the product flows from that — which is why it feels narrow to a small business and exactly right to a newsletter writer.

Pros:

Tagging and automation that match how creators think. Subscribers carry tags and move through visual “if this, then that” sequences — no juggling duplicate lists, no fighting the tool to run a launch or an evergreen sequence.
Strong deliverability reputation. Kit pours its engineering into the unglamorous part of email: landing in the inbox. For a creator, that matters more than any template.
Built-in creator commerce. You can sell digital products and paid newsletters directly to your list without bolting on a separate checkout for simple offers.
A creator network that can grow your list. Kit’s recommendation features can put your newsletter in front of other creators’ audiences — genuine list growth, not just list management.
A free tier to start, with pricing that scales with subscriber count as standard.

Cons:

Plain email design — on purpose. If you want glossy, image-heavy brand campaigns, Kit’s deliberately simple editor and templates will feel spartan next to Mailchimp’s library.
Creator-focused, not general-purpose. It doesn’t try to be a small-business marketing suite; companies wanting campaigns, broad audience tools and a website-ish surface will find it narrow.
Costs scale with the list. Standard for the category, but worth naming: a big audience means a real monthly bill, and the free tier is a starting point rather than a place to stay.
Selling beyond simple offers needs more tools. Kit’s commerce handles digital products and paid newsletters well, but full funnels, courses with memberships, and upsell flows usually mean adding another platform.

Kit suits creators — newsletter writers, course creators, audience-first solo businesses — who want their email tool to disappear into the background and just deliver, segment and sell.

Head-to-head: the differences that actually matter

Email design and templates

Mailchimp wins. Its template library and editor are built for designed, branded campaigns. Kit’s plain-by-design emails are a feature for creators (personal emails convert) but a limitation for brands that need visual polish.

Automation and segmentation for an audience business

Kit wins. Tag-based subscriber management and visual behavioural sequences are its core; Mailchimp can automate, but more of its advanced automation sits behind higher tiers, and its campaign-centric model makes audience-style publishing feel like a workaround.

Pricing model

Closer than it looks — different gotchas. Both have free tiers; both get pricier as the list grows. Mailchimp’s catch is billing based on stored contacts (historically including unsubscribed ones, depending on settings), so hygiene affects cost. Kit’s pricing follows subscriber count in the standard way. Whichever you pick, confirm current pricing on their sites — these details change.

Selling to your list

Kit wins for creators. Digital products and paid newsletters are built in. Mailchimp’s strength is promoting a business rather than being the storefront. Neither is a full funnel-and-course platform — that’s the gap the next section covers.

Breadth beyond email

Mailchimp wins. Landing pages, forms, broader campaign types and a huge integration ecosystem make it the more complete marketing suite. Kit deliberately stays in its lane.

Where Systeme.io fits

Here’s the part most Mailchimp-vs-ConvertKit comparisons skip: both tools are email-first. The moment your plan includes a sales funnel, a course, a proper checkout with order bumps, or an affiliate program, you’re adding — and paying for — more tools on top of either one.

If that’s where you’re heading, it’s worth knowing a third option exists: Systeme.io bundles email automation alongside funnels, course hosting, a blog and an affiliate program — with a genuinely free plan that has no time limit. The honest trade-offs: its email editor is plainer than Mailchimp’s, and its creator-specific features (tagging depth, deliverability focus, creator network) are shallower than Kit’s. But as one free hub to run an entire small online business from, neither Mailchimp nor Kit competes with it on cost.

We’ve compared it directly with both tools: Systeme.io vs Mailchimp and ConvertKit vs Systeme.io.

So which should you choose?

Choose Mailchimp if:

You’re a small business emailing customers, not a creator building an audience.
Designed, branded campaigns matter to your image.
You want one familiar tool that also covers landing pages, forms and broad marketing jobs.

Choose Kit (ConvertKit) if:

You’re a creator: a newsletter, a course, an audience-first business.
Tag-based automation, deliverability and selling directly to your list matter more than visual templates.
You want creator-native features like a recommendation network and paid newsletters.

Start with Systeme.io if:

You need email plus funnels, a course or a real checkout, and you’d rather not stack subscriptions.
You’re early enough that a genuinely free all-in-one beats a best-in-class specialist.
You’d rather validate the business first and graduate to a specialist tool (Kit for email depth, Mailchimp for brand campaigns) once revenue justifies it.

A practical shortcut: build your next email in each tool’s free tier before committing. An hour inside each will tell you faster than any comparison whether you’re a “campaigns” person or a “sequences” person.

Frequently asked questions

What's the main difference between Mailchimp and ConvertKit (Kit)?

They're built for different people. Mailchimp is a general-purpose marketing platform for small businesses — design-led email templates, campaigns, landing pages and a broad feature surface. ConvertKit (now branded Kit) is built specifically for creators: newsletter writers, course creators and audience-first businesses. Kit centres on subscriber tagging, visual automation sequences and selling digital products directly to your list, with deliberately plain email design. In short: Mailchimp is a marketing suite for a business; Kit is an audience engine for a creator.

Is Mailchimp or ConvertKit cheaper?

Both have free tiers and both get more expensive as your list grows, so the sticker comparison shifts with your subscriber count. The gotcha to know on Mailchimp's side: its billing has historically been based on the contacts stored in your audience — which can include unsubscribed and non-buying contacts depending on settings — so list housekeeping directly affects your bill. Kit's pricing scales with subscriber count too, which is standard for email platforms. Check current pricing on both sites before deciding, and if budget is the deciding factor, a free all-in-one like Systeme.io may cover you entirely while your list is small.

Is ConvertKit better than Mailchimp for creators?

For most creators, yes — that's exactly who Kit is designed for. Subscriber tagging and behavioural automation map to how creators actually run a list, the editor is built for simple personal-feeling emails rather than glossy brand campaigns, you can sell digital products and paid newsletters directly, and its creator network can put your newsletter in front of new readers. The trade-off is plainer email design and a deliberately narrower focus: if you want designed brand campaigns or a broader small-business marketing suite, Mailchimp serves that better.

Why do people switch from Mailchimp to ConvertKit?

The most common pattern is creators who started on Mailchimp because it's the name everyone knows, then found the campaign-and-template model doesn't match an audience-first business. They want tags instead of separate lists, behaviour-triggered sequences without fighting tier limits, and a way to sell to their list directly. Cost also plays a part — Mailchimp's contact-based billing plus features gated to higher tiers can make a growing creator list feel expensive for what's actually being used.

Is it hard to switch between Mailchimp and ConvertKit?

Not particularly. Both let you export your subscribers as a CSV and import them into the other tool. What doesn't transfer automatically is the surrounding work: signup forms, automations and email templates need rebuilding in the new platform, and you'll want to reconnect the forms on your site. Plan a quiet week, run both in parallel briefly if you want a safety net, and send a short re-introduction email from the new platform so subscribers recognise the sender.

Is there a free alternative that does more than email?

Yes. Both Mailchimp and Kit are email-first tools — if you also need sales funnels, a course, a proper checkout or an affiliate program, you'll be adding more tools on top. Systeme.io bundles all of those alongside email automation, with a genuinely free plan that has no time limit. Its email editor is plainer than Mailchimp's and its creator features are shallower than Kit's, but as one free hub for a whole small online business, it's often the most economical starting point.
