What MailSenpai MCP can do

The server needs sign-in before it lists its tools, and MailSenpai's documentation doesn't name them, so this is what it says the server can do (read 7 Oct 2026). It may be out of date.

    Read-only
  • List, create, edit and copy lists and custom fields
  • Create segments with conditions and read their subscribers
  • Search, add, update, unsubscribe; imports within plan limits
  • List, search, create and update templates
  • Draft, schedule, pause; sending only with explicit confirmation
  • Campaign statistics and recorded bounces
    Read-only
  • List and, if your plan allows it, create transactional emails
