A real, verifiable email address for every agent — so it can sign up for services and receive confirmations, verification codes, and receipts. Provision one in a single API call; idle inboxes cost next to nothing.
Memory
Every message is parsed, threaded, and stored — a durable, structured record your agent can read back whenever it needs the context. No IMAP, no MIME parsing.
SDKs, CLI & MCP
Typed Python and TypeScript SDKs, a CLI, and a hosted MCP server, so agents can read their mail with no glue code.
Usage-based, no seats
Billed by inboxes and inbound volume — not per mailbox. Start free, upgrade when your agents grow.
