Kit and MailerLite both send newsletters, run automations and sell simple digital products. Kit is the email platform that used to be called ConvertKit, and it is built for creators and experts who sell what they know. MailerLite is a general email tool for small businesses. The right pick depends on your list size and whether you plan to sell through it.
Kit confirms the name change on its own blog: ConvertKit is now Kit. All prices below come from the Kit pricing page and the MailerLite pricing page, as of October 2026, in US dollars.
The short verdict
- Pick Kit if you expect your list to grow into the thousands before you pay anything, you mainly send broadcasts for now, and you plan to sell courses, guides or paid newsletters.
- Pick MailerLite if you want automations such as a welcome series on the free plan, or you want lower monthly prices while your list is small.
Free plans side by side
Kit Free:
- Up to 10,000 subscribers.
- Unlimited landing pages, forms and email broadcasts.
- Tagging and segments.
- Sell digital products and subscriptions.
- 1 user.
- No visual automations or email sequences.
MailerLite Free:
- Up to 250 subscribers and 2,500 emails a month.
- 3 active automations, each with up to 5 steps.
- 1 website, 1 landing page and 3 active forms.
- 1 digital product or booking.
- 2 user seats and community support.
The trade-off is clear. Kit lets your list grow much bigger for free, but every email goes out by hand. MailerLite caps the list early, but a new subscriber can get a welcome email on their own from day one.
Paid plans
Kit, priced for 1,000 subscribers:
- Creator: $39 a month billed monthly, or $33 a month billed yearly ($390 a year). Unlimited automations and sequences, removes Kit branding, 2 users, 24/7 email and chat support.

The differences that matter
Automations
On Kit, automations and sequences start on Creator. On MailerLite, you get 3 small automations for free and 50 on Comfort. If a welcome series is the main thing you need, MailerLite covers it for less.
Selling
Both let you sell digital products and paid newsletters.
- Kit charges 3.5% plus 30 cents per sale on every plan. Kit says this includes credit card processing.
- MailerLite says it takes no commission on digital products. You pay Stripe's processing fee (selling digital products). MailerLite lists paid newsletters on Comfort.
If you sell a lot, work out both fees on your expected monthly sales.
Websites
MailerLite includes a website builder on every plan: 1 site on Free, 10 on Comfort and unlimited on Power. Kit offers unlimited landing pages and a newsletter site. If you have no website yet, MailerLite gives you more to work with.
Support
Kit lists 24/7 email and chat support from Creator. MailerLite lists email support on Comfort and 24/7 live chat on Power.
