mailvalide — Human Approval for AI Email

Why it surfaced

mailvalide defines a four-stage circuit—prepare, show, validation, valide—and makes the boundary unusually explicit: the AI can build a complete .eml file, but only a person can type the command that sends it. The page also documents operational safeguards including real-client preview, sender copies, draft archiving, recoverable deletion, and separate read/send permissions.

An open-source Linux/Python tool that lets AI prepare email drafts while reserving the actual send command for a human.
