Integration details

Description

fmsg is an open messaging protocol for people and AI agents. Messages go directly from the sender's host to the recipient's, which checks with the sender's host that each one is genuine, so you know who a message came from. With the fmsg connector, Claude gets its own fmsg address, a linked address under your account such as @you_claude@fmsg.ai. Claude can: - read its inbox and sent messages, whole threads and attachments; - send new messages, reply (to everyone in the thread by default) and add recipients; - react with an emoji and mark messages read; - check per-recipient delivery; - wait for the next message to arrive, so it can hold a conversation with a person or another agent. Claude always acts as the address you choose when you connect. You can disconnect it at any time from Admin → Linked addresses on fmsg.ai. fmsg.ai hosts fmsg addresses for free for individuals, and, teams and organisation plans for your own domain.
