ConvertKit vs MailerLite: Best Email Platform for Creators and Small Businesses

Email is the one marketing channel you actually own, which makes picking the wrong platform a genuinely expensive mistake. ConvertKit (now sometimes branded as Kit) and MailerLite both target creators and small businesses, both have loyal followings, and both are good. But they solve slightly different problems, and choosing based on a feature checklist instead of how you actually work is how people end up migrating twice.

I’ve run lists on both. Here’s the real difference.

Who each one is built for

ConvertKit was built by and for creators — newsletter writers, course sellers, coaches. Its DNA is audience growth and selling digital products. MailerLite is more of a general-purpose small-business email tool: newsletters, yes, but also ecommerce, landing pages, and broader marketing. If you’re a creator monetizing an audience, ConvertKit’s worldview will feel native. If you’re a small business that also happens to send email, MailerLite’s breadth fits better.

Automation

Both offer visual automation builders. ConvertKit’s is clean and tag-based, which makes subscriber segmentation feel intuitive — you tag people by behavior and build sequences off those tags. MailerLite’s automation is genuinely capable and, for the price, almost surprisingly so. Power users sometimes hit ConvertKit’s ceiling on complex branching logic; MailerLite holds up well for most small-business needs.

Ease of use

MailerLite is the easier tool to learn cold. Its editor is friendly and its templates are more polished out of the box. ConvertKit is deliberately minimalist — plain-text-style emails convert well and that’s intentional — but if you want rich, designed newsletters, MailerLite gets you there faster.

Pricing

This is where MailerLite makes its loudest argument. At comparable subscriber counts, MailerLite is consistently cheaper, and its free tier is generous. ConvertKit also has a free tier and reasonable paid plans, but you’re paying a premium for the creator-focused ecosystem and selling tools. If budget is tight and you’re under a few thousand subscribers, MailerLite stretches further.

Selling and monetization

ConvertKit pulls ahead if selling digital products is core to your business. Its commerce features, tip jars, and paid-newsletter support are built in and well-integrated. MailerLite has ecommerce features too, but ConvertKit’s are more native to the creator-selling motion.

Who each one is for

• Choose ConvertKit if: you’re a creator monetizing an audience, you sell courses or digital products, and tag-based subscriber management fits how you think.
• Choose MailerLite if: you want the best value, the easier editor, and a general-purpose tool that handles newsletters, landing pages, and light ecommerce.

My recommendation

For most small businesses watching their budget, start with MailerLite — the value and ease are hard to argue with. For creators whose business is their audience, ConvertKit’s selling tools and creator-first design justify the premium. The mistake to avoid is overbuying: don’t pay for ConvertKit’s monetization stack if you’re just sending a monthly update. Match the tool to the motion.
