ConvertKit (Kit)

Built for creators, coaches & independent businesses who want deep relationships with their audience.

Creator-first

Mailchimp

The industry veteran. Familiar, feature-rich, and now — for many small businesses — frustratingly expensive.

All-in-one

Mailchimp

ConvertKit

There is a moment every small business owner knows well. You are sitting at your desk, staring at an email dashboard, and something feels off. The tool that was supposed to make your life easier has somehow made it harder. Pricier. More confusing. You wonder if you made the right choice.

If that tool is Mailchimp, you are not alone. And if you have been eyeing ConvertKit — now rebranded as Kit — as a possible escape route, this comparison was written specifically for you.

Let’s cut through the noise, skip the jargon, and talk about what actually matters: your time, your money, your sanity, and the real people behind every email address on your list.

The philosophy behind each tool

Every piece of software is built around a belief. Understanding that belief tells you more about a tool than any feature list ever could.

Mailchimp was born in 2001 as a scrappy, fun email tool for small businesses. That spirit is still visible in its quirky monkey mascot and playful copy. But over the years, Mailchimp evolved — or tried to — into an all-in-one marketing platform. It added websites, social media scheduling, postcards, landing pages, CRM features. The result is a product that tries to do everything and, for many users, now does everything just well enough to be underwhelming.

ConvertKit took a completely different path. Its founder Nathan Barry built it out of pure frustration — he was a creator who felt that existing email tools didn’t understand him. So he built one that did. ConvertKit is obsessively focused on one thing: helping creators and small business owners build genuine, lasting connections with their audiences. That single-minded focus is both its greatest strength and, for some users, its only limitation.

«Mailchimp gives you a Swiss Army knife. ConvertKit gives you a scalpel. One does everything. The other does one thing brilliantly.»

Pricing: where the relationship gets complicated

Money is emotional. Especially when you are running a small business and every single expense feels personal. So let’s be direct about what each tool actually costs.

Mailchimp’s free plan caps at just 500 contacts. The moment your list grows beyond that — and you should want it to — the price increases rapidly. By the time you reach 5,000 subscribers, you could be paying over $75 per month on the Essentials plan. And some critical features, like advanced segmentation and A/B testing, are locked behind the more expensive Standard tier.

ConvertKit’s free plan is startlingly generous: up to 10,000 subscribers, with unlimited landing pages, forms, and email broadcasts. Yes, automations require a paid plan — but the paid plans feel fair, transparent, and predictable. There are no hidden jumps, no sudden price walls that punish your growth.

For a small business owner counting every euro, that difference is not just financial. It is deeply emotional. It is the difference between feeling supported and feeling squeezed.

The audience relationship: where ConvertKit wins hearts

Here is something Mailchimp has never fully understood: your subscribers are not a list. They are people. Real, curious, busy, distracted people who chose to trust you with their inbox — which is one of the most intimate spaces in their digital lives.

ConvertKit’s tag-based system reflects this beautifully. Instead of splitting your audience into separate lists (which creates chaos and duplicate billing on Mailchimp), ConvertKit keeps everyone in one place and lets you tag them based on their behavior, interests, and actions. Someone who clicked on your pricing page gets a different tag than someone who downloaded your free guide. Your emails become personal. Relevant. Welcome.

Mailchimp’s list-based approach, by contrast, can quickly become a tangled web. Moving subscribers between lists is clunky. Contacts can appear on multiple lists and be counted — and billed — multiple times. It is a system that made sense in 2005. In 2025, it feels like driving with a paper map.

Who should choose ConvertKit?

If you are a blogger, podcaster, online coach, course creator, writer, or independent consultant, ConvertKit will feel like it was made just for you — because it was. If your entire business lives in the relationship between you and your audience, if your emails are conversations rather than promotions, and if you value simplicity and clarity over feature overload, this tool will quietly transform your marketing.

Who should stick with Mailchimp?

If you run a brick-and-mortar business, an e-commerce store, or a larger organization that needs deep integrations, complex reporting, or a wide variety of visual email templates, Mailchimp’s broader feature set may justify its higher cost. It is also worth considering if your team is already deeply trained on it and the switching cost feels too high right now.

The emotional verdict

Every tool you use shapes how you feel about your work. The best email marketing platform is not necessarily the one with the most features — it is the one that makes you feel capable, confident, and excited to communicate with your audience.

For the vast majority of small business owners and independent creators, ConvertKit earns that feeling. It is lean, honest, and human in a way that Mailchimp — with all its ambition — has slowly stopped being.

But only you know your business. Trust that knowledge. And trust yourself to make the right call.
