nicemails

nicemails gives one account many real, independent mailboxes on a shared domain, one for each client, project or AI agent. This connector lets Claude work with those mailboxes: list them, read and search messages, pick up verification codes, organize mail with folders and flags, create new mailboxes, and send mail.

You choose what Claude can do when you connect: read only, manage, or send, for every mailbox or just one. Sending to a new recipient is held until you approve it on a nicemails confirmation page while signed in. Email content is returned as untrusted data.
