ConvertKit vs MailerLite: Best Email Platform for Creators and Small Businesses
Email is still the only channel you fully own, but choosing a platform locks in pricing and features for years. ConvertKit (now Kit) and MailerLite both target creators and small businesses, and both can grow with you to 100k subscribers. The differences show up in tagging logic, automation flexibility, and how much you’ll pay at scale.
We dug into ConvertKit and MailerLite the way a small-business owner actually evaluates software: what does it cost a year from now, who on the team will own it daily, and which one does the team actually open on Monday morning? Feature lists are easy to skim. Daily-use fit is harder to measure but it’s the thing that decides whether the tool pays back its subscription or quietly becomes a sunk cost.
This comparison is built for teams of 1–50 — small enough that one wrong tool choice noticeably hurts, large enough that adoption habits across multiple people matter. Both ConvertKit and MailerLite are competent products from established companies, so this isn’t a “don’t use the bad one” piece. It’s about matching the right tool to your specific workflow, budget, and team composition.
ConvertKit vs MailerLite: which to pick at a glance
Before getting into details, here’s how the two stack up across the points that actually drive a decision for small businesses and lean teams. We evaluated each across pricing transparency, daily-use ergonomics, scale of feature depth, and how well each one handles real-world workflows rather than demo scenarios.
| Feature | Tool A | Tool B | Winner |
|---|---|---|---|
| Free plan | Up to 10,000 subs (Newsletter only) | Up to 1,000 subs, 12k emails/mo | ConvertKit |
| Paid at 5k contacts | $66/mo (Creator) | $39/mo (Growing) | MailerLite |
| Paid at 25k contacts | $179/mo | $89/mo | MailerLite |
| Automation builder | Visual + tag-based | Visual + group-based | ConvertKit |
| Landing pages | Built-in, decent templates | Built-in, more design-forward | MailerLite |
| Creator monetization | Tip jars, paid newsletters, sponsorships | Limited | ConvertKit |
| Ecommerce integrations | Shopify, Stripe, Gumroad | Shopify, WooCommerce, Stripe | Tie |
| Deliverability | Strong (~95% inbox) | Strong (~94% inbox) | Tie |
Where ConvertKit wins
ConvertKit was built by creators for creators, and it shows in features like tip jars, paid newsletter subscriptions, the Creator Network (recommendations between newsletters), and Sponsorships for monetizing your list. None of that is glued-on — it’s first-class.
Tag-based subscriber management is more intuitive than MailerLite’s group model when your funnels get complex. You can tag based on link clicks, form submissions, purchases, or automation paths, and use those tags for hyper-targeted broadcasts. For creators running multiple courses or lead magnets, this clarity matters.
The pattern across these strengths is that ConvertKit optimizes for one set of users doing one set of jobs well. If that user and that job match yours, the daily-use compounding is real — small teams ship more with less friction. If they don’t match, you’ll feel the gap quickly and lean toward MailerLite.
Where MailerLite wins
MailerLite is meaningfully cheaper at every contact tier. At 5,000 contacts you’ll pay around $39/month vs ConvertKit’s $66; at 25,000 the gap widens to roughly $89 vs $179. For bootstrapped creators or small businesses where email isn’t yet the primary revenue driver, that’s real money.
The MailerLite drag-and-drop editor is the friendlier one — newcomers ship campaigns faster, landing pages and forms are simpler to assemble, and the templates are modern. If you want a wysiwyg experience and don’t need advanced creator monetization, MailerLite gets you to “sent” with less friction.
If your team’s workflows lean toward the strengths above, MailerLite pays for itself within the first quarter. The question to ask yourself is which set of strengths maps onto the work you actually do — not which sounds more impressive in a sales demo. Plenty of teams have bought the more powerful tool only to use 20% of it.
Pricing breakdown
Both have free tiers but they’re shaped differently — ConvertKit’s free plan is generous at 10k subscribers (newsletter only), MailerLite’s is 1k subscribers with the full feature set. Paid plans cross around the 1.5k-2k subscriber mark, and MailerLite stays cheaper from there. If price is a deciding factor, MailerLite’s pricing is roughly 50-60% of ConvertKit’s at every tier above 5k.
One thing the headline pricing rarely captures: time-cost. The cheaper tool can be the more expensive one once you factor in setup hours, training, integration work, and the productivity loss while your team adapts. For a 10-person team, even a $50/month savings is dwarfed by a single week of slower onboarding. Run the math on total cost, not list price.
Real-world scenarios
The solo founder who wants to ship now. Pick the tool with the lower setup tax. Whichever of ConvertKit or MailerLite you can have running in an afternoon is the right answer at this stage. Optimize for speed-to-value; you can migrate later if you outgrow it. Don’t pre-optimize for a team you don’t have yet.
The 10-person team consolidating tools. The right pick is the one that replaces the most existing subscriptions without losing workflows that are already working. Audit what your team uses today, score how each candidate covers those use cases, and add a one-month parallel run to your decision plan before fully cutting over. Tool transitions burn weeks if rushed.
The growing team approaching 50 people. Look past today and pick for the team you’ll be in 18 months. Switching costs scale with usage — by the time you have 50 people using a tool, migrating off it is a quarter-long project. If ConvertKit hits its ceiling around your projected size, MailerLite is the better bet now even if it’s mildly heavier today.
Who should pick what
Pick ConvertKit if:
- You’re a creator running paid newsletters, courses, or coaching with multiple funnels
- You want monetization features (sponsorships, tip jars) built into the platform
- Tag-based automation logic matches how you think about your audience
Pick MailerLite if:
- You’re price-sensitive and want a tool that scales to 25k+ contacts cheaply
- You design-driven and want better-looking landing pages and forms by default
- You’re a small business doing transactional + marketing email, not creator monetization
Migration and switching costs
Both ConvertKit and MailerLite have export tools and migration paths, but switching is never as clean as the vendor blogs suggest. Plan for two to four weeks of dual-running during any real migration: one team learning the new tool while another keeps the old one running for in-flight work. Data exports usually preserve the obvious fields and lose the small stuff (custom views, automations, templates) that took months to set up. Factor that into your initial choice — it’s easier to pick well now than to migrate later.
One useful trick: before signing a long-term contract on either ConvertKit or MailerLite, export a sample of your current data and try to import it. The friction (or absence of it) you hit in that sample is a good preview of the real migration experience. Vendors that make import easy generally make export easy too — and that ease is a quiet signal that the company doesn’t fear you leaving, which is usually a sign of a healthy product. The reverse is also worth noting: any vendor who makes export hard is telling you something about their confidence in their own retention.
- MailerLite is the price winner at every tier above the free plan
- ConvertKit (Kit) wins for creators with monetization needs and complex tagging
- Both have similar deliverability — neither is a meaningful edge over the other
- MailerLite’s editor is the easier on-ramp for non-marketers
- Switching later is painful — pick based on 12-month trajectory, not today’s list size
Frequently asked questions
Is ConvertKit really free up to 10,000 subscribers?
Yes, but you only get the Newsletter plan features — no visual automations, no advanced reporting, no integrations. It’s enough to start collecting emails; you’ll outgrow it once you need any sequence or behavior-based logic.
Can I import my list from Mailchimp easily?
Both platforms have CSV import and dedicated Mailchimp migration tools. ConvertKit’s tag mapping is smoother during import; MailerLite handles groups conversion well but expect to clean up some segmentation manually.
Which one has better deliverability?
They’re effectively tied for legitimate senders. Deliverability depends much more on your list hygiene and content than the platform — both clear 90%+ inbox placement when used correctly.
Does MailerLite support paid newsletters?
Limited support via Stripe integration for membership-style flows, but it’s not the same as ConvertKit’s native paid newsletter feature. If paid newsletters are central, ConvertKit is the better fit.
Bottom line
ConvertKit and MailerLite both solve the same surface problem but make different bets about the team using them. Re-read the quick answer at the top of this post: that recommendation accounts for the majority of small-business scenarios. The edge cases — where one tool clearly fits and the other clearly doesn’t — are spelled out in the “Pick if” sections above. Use the free tier or trial on your front-runner before you pay, and decide based on what your team actually does, not what the marketing pages promise.
Whichever way you lean, the cost of switching tools is real. Run a one-week trial on the front-runner with at least two team members touching it daily, then decide. The team that ends up using ConvertKit or MailerLite will tell you which one fits faster than any feature comparison can.
