Mailchimp vs ConvertKit vs ActiveCampaign: Which One Sucks Less? – Top Tool Guides

Quick Verdict

Look, none of these tools are perfect. Mailchimp is the bloated ex you keep blocking then unblocking. ConvertKit is the minimalist who only wears grey t-shirts but actually knows what they’re doing. ActiveCampaign is the overachiever who brings 47 spreadsheets to a potluck. I’d personally take ConvertKit for newsletters, ActiveCampaign if you need heavy automation, and Mailchimp only if you enjoy pain.

ConvertKit ★★★★☆ (4/5) – best for writers & creators
ActiveCampaign ★★★★ (4/5) – automation beast, steep learning curve
Mailchimp ★★½ (2.5/5) – good branding, bad everything else

Three months ago I was sitting in my kitchen at 11pm eating cold pizza straight from the box, staring at a spreadsheet with 1,200 subscribers and zero revenue. I’d been building a newsletter about obscure beetles (yes, really) and my free Mailchimp account had just hit the limit. Time to pick a grownup tool.

First I tried Mailchimp again — because I have the memory of a goldfish. I’d used it years ago and remembered the cute chimp logo. That’s where the good memories end. The new interface is like a furniture store that rearranges everything every week. I spent 45 minutes trying to find the “create campaign” button. Then I accidentally emailed my entire list a test subject line that read “TEST BEETLE NEWSLETTER – IGNORE.” Three people unsubscribed. My newsletter about beetles. I wanted to throw my laptop.

What nobody tells you about Mailchimp: they nickel-and-dime you on contacts. Have 2,001 subscribers? That’s the next pricing tier. Their support is a chat bot that might as well be a toaster. And their deliverability? My open rates dropped to 18%. I’d rather hand-deliver newsletters on papyrus.

Then ConvertKit. Oh, ConvertKit. It’s ugly in a beautiful way. The interface looks like it was designed in 2008 and never updated. But god, it just works. Signing up took 4 minutes. No endless tutorials. I imported my list without any formatting drama. The visual automation builder is actually logical — if X happens, do Y. I set up a welcome sequence in 20 minutes. My open rates jumped to 42%.

But ConvertKit’s missing pieces drove me insane. No proper A/B testing without third-party hacks. The form builder is basic as hell. You want to track custom tags? Good luck, you need to manually type every single one. And their pricing is per-subscriber, which stings when you’re growing.

ActiveCampaign came next. I felt like I’d walked into a space shuttle cockpit. It has every feature you could ever want: CRM, predictive sending, split automations, even a full email builder that doesn’t break. I spent a weekend mapping out a 27-step automation for beetle enthusiasts who might also like moth content. It was beautiful. Then I realized I had no idea how to actually trigger it. The interface is powerful but it’s like trying to read Finnegans Wake while doing calculus.

The hidden cost with ActiveCampaign: it’s not the $49/month. It’s the time you spend building automations that you’ll probably never use. I also discovered their “free migration” service, which turned into a nightmare when they transferred only half my forms and then ghosted me. Their support took 3 business days to reply to a priority ticket. For something this complex, that’s a dealbreaker.

The parts nobody talks about

First: all three tools have hidden fees if you need transactional emails. Mailchimp’s “free” plan doesn’t include any; you pay per thousand. ConvertKit’s pro plan requires annual commitment for a reasonable rate. ActiveCampaign charges for SMS sending like it’s platinum.

Second: list cleaning. Mailchimp automatically purges inactive contacts after a while, which sounds helpful until you realize you paid for them. ConvertKit lets you hoard dead subscribers forever. ActiveCampaign has a “suppression list” that’s actually useful.

Third: the support experience. Mailchimp’s is outsourced and robotic. ConvertKit’s founders are active on Twitter and answer customer emails themselves occasionally. ActiveCampaign used to have great support, but after they raised that $200M round, quality dropped like a brick.

What I Actually Use Now

ConvertKit. No contest. I’m at 4,800 subscribers now — beetle lovers from 14 countries — and ConvertKit handles it better than any other tool. Yes, the design is ugly. Yes, I wish they had better segmentation. But I spend 95% of my time writing and sending emails, not debugging broken automations. Open rates are consistently above 40%. I haven’t had a support issue in months because the platform doesn’t break.

If you’re doing complex sales funnels with multiple products, ActiveCampaign is better. But for a newsletter that exists to connect with people who actually read? ConvertKit wins by being boring and reliable.

Mailchimp? I’ll never use it again. Not even for free.
