Introducing Mailgent: give your AI agent an inbox
Email and identity for AI agents — a real address, a vault, 2FA, a calendar, a verifiable identity, and a wallet, all from one API call.
AI agents can reason, plan, and call tools. But the moment they try to act in the world, they hit a wall built for humans: a sign-up form that wants an email, a verification link, a 2FA prompt, a payment screen. An agent without an identity stalls at the first gate.
Mailgent is the identity stack that gets agents past those gates. It leads with email — a real, deliverable inbox every agent owns — and adds the capabilities an operating agent needs around it. Today it's generally available.
Why we lead with email
Email is the identity primitive the world already agreed on. It's how you sign up, how you verify, how you get the receipt, and how a person replies. Give an agent its own address and it stops depending on a human to relay messages in and out.
So the first thing Mailgent gives an agent is a real inbox at name@mailgent.dev — deliverable, with DKIM and SPF handled, reachable over a clean API or MCP.
Identity is the root of trust
Around the inbox sits the rest of what an agent needs: an encrypted vault for secrets, TOTP to clear 2FA gates, a calendar to coordinate time, a did:web identity with an Ed25519 key to sign and prove who it is, and a USDC wallet to pay per call under mandates you set.
All of it hangs off one identity, gated by scopes on the agent's key. You grant exactly what an agent should do, and every action is logged and attributable.
One call to provision
You don't wire six services together. A single signup call returns a platform key and an agent identity with an address, scopes, and the keys behind it — ready to use over REST or as MCP tools in Claude, Cursor, and anything else that speaks the protocol.
