email59's MCP server lets an agent send email on its own. It signs up by asking for a 6-digit code at an address it can read, then uses the session key for everything else. Mail goes out from a name you choose at email59.com, so there's no domain to verify before the first send. Email is sent from @email59.com and replies aren't received yet.
