Welcome

OpenEmail is an email client built around domains you own rather than mailboxes we rent you. This is the whole product, written down.

What OpenEmail is

You point a domain at OpenEmail and every address you create on it becomes real. With catch-all switched on, so do the ones you have not created. One inbox holds all of them, and you send from any address on any verified domain.

  • Priced per workspace rather than per seat, so adding a colleague to a paid plan never changes the bill.
  • Operable by software as well as by people: the MCP server exposes the mailbox to any MCP client.

Anything not shipped is marked as such rather than left out. A reference that only lists what works cannot be trusted about what does not.
