Who is MailCheap best for?

MailCheap is best for newsletter writers with large lists who want to pay per email sent, not per subscriber.

  • Leaving beehiiv or Substack

    It imports their CSV exports with each reader's status and signup date, and also takes Kit, MailerLite, Ghost and Buttondown files.

  • Lists with many quiet readers

    Plans count emails sent, and list cleanup stops mailing readers who ignore several issues.

  • Running a newsletter from an AI agent

    Its MCP server lets ChatGPT, Claude, Cursor or Codex draft, schedule and report on issues, and asks you before any send.

  • A web home for every issue

    Each issue gets a page search engines can find, with a signup form, on a free subdomain or your own server.

MailCheap is free to self-host, and MailCheap Cloud starts at $19 a month on Starter for 20,000 emails and up to 10,000 subscribers, with no free plan or trial.
