MailerLite vs Kit: Agent Access, Publishing and Price

The short answer: if you want an AI assistant working in your email account before you pay anything, MailerLite is the one to start with: its free plan lists MCP access, limited and without sending, and its Comfort plan opens full MCP and API access from $12 a month for 500 subscribers on monthly billing (MailerLite pricing). Kit puts its MCP server on its paid Creator and Creator Pro plans (Kit MCP docs) and is the stronger fit when your growth runs through other creators and the apps built for them.

A gap to state first. Kit's pricing page and help centre returned a security check instead of their content on 26 October 2026, so this page quotes no Kit price and relies on Kit's developer documentation, which loaded normally. Open Kit's pricing page with your list size before you decide; the comparison below tells you what to look for on it.

Before you move a list:

1. Work out what one month of sending needs. MailerLite's Comfort plan allows ten times the top of your band (pricing FAQ). For example, 900 subscribers sit in the 1,000 band, which allows 10,000 emails; a weekly issue is 4 x 900 = 3,600, and a five-email welcome series for 100 new people adds 500, for 4,100 in total. Comfort covers that with room to spare, and the same sum tells you which Kit tier to price.
2. Map your tags before you export. Kit targets broadcasts by segment or tag (broadcast reference); MailerLite works with groups and segments. Write down which of today's tags become groups, so sequences and automations rebuild cleanly on either side.
3. Name what the assistant has to save you. Hours per issue, or the time from idea to scheduled draft. Time one issue the way you work now, so you can tell later whether the agent earns its seat.

Questions a buyer asks

Where the two pull apart

Which plan lets an agent in

MailerLite treats the MCP server as a feature of every plan, scaled by plan: the free tier can read and draft but not send through it, and Comfort and Power list full MCP and API access (pricing FAQ). Kit's documentation is direct that the Kit MCP is available on all paid plans, Creator and Creator Pro (Kit MCP). If you are still choosing a tool, only MailerLite lets you test agent work at zero cost.

Discovery against a site of your own

Kit's model is built around creators finding each other: every account has a Creator Profile, the public identity shown in the Creator Network, and a broadcast can be published to the web as well as sent (Creator Profile, broadcasts). MailerLite's model is a site of your own: websites, landing pages, a blog section and paid newsletters, with ten sites on Comfort (pricing).

What a published price is worth

MailerLite publishes every band up to 200,000 subscribers on its pricing page, so the figure for 5,000 subscribers, $49 on Comfort, is checkable before you talk to anyone. For Kit, the same check has to be done on its own page. That is not a mark against Kit's product; it is a reason to do the reading before the trial rather than after it.

One task, two connectors

The job: draft a win-back email for subscribers who stopped clicking, and have it ready for a person to approve. In MailerLite, connect the MCP server to Claude or ChatGPT and ask it to build the segment and draft the campaign; the MCP page says campaigns are always drafts first and nothing sends without your confirmation. In Kit, the MCP maps the v4 API, where a broadcast saved with no send time stays a draft (broadcast reference), and Kit says sending always needs explicit confirmation in supported clients (Kit MCP). In both, the human check is the same and should stay with one named person: read the draft, check the segment size, then send.

The zero-cost test

Open MailerLite's free plan, connect the MCP server and ask it three questions about a test list: which group is largest, which subject line drew the most opens, and draft next week's issue. Then open Kit's pricing page and note the tier for your list. If the free test shows you would use the agent every week, price both paid plans on the same sum from the list at the top.

MailerLite's pricing page opens on yearly billing, so the first figure you see for Comfort at 500 subscribers is $10.80, not the $12 you pay month to month (pricing). A page that leads with the yearly number is steering you toward the yearly commitment. If there is a chance you leave within the year, $12 is your number.

FAQ

Can Kit's MCP server send a broadcast on its own?

Kit says destructive or external actions, sending broadcasts and deleting data among them, always require explicit user confirmation in clients that support its tool annotations (Kit MCP).

Does MailerLite's free plan include the MCP server?

Yes, in a limited form: the pricing FAQ says API and MCP access on Free does not include sending, and that sending through them needs a paid plan (MailerLite pricing).

Where do I find Kit's prices?

On kit.com/pricing. It could not be read for this page on 26 October 2026, so no Kit figure appears here.
