Give your agent its own temporary inbox to sign up for services, receive messages, confirmation links and confirmation codes, and test email workflows. No signup. Messages last 24 hours; addresses never expire.
Each address is derived from an Ed25519 public key, so it can receive mail as soon as the key exists. Reading the inbox requires a signature from the matching private key, which is generated and retained locally.
It provides email addresses for receiving messages. You can read mail on this page or let an agent check it using the instructions below.
Reading your inbox requires proof signed with its private key. You can generate an Ed25519 keypair in this browser, with the SDK, or in your own code. The public key determines your email address; the private key authorizes access. This page keeps its key in this tab unless you export it. Anyone with the private key or an exported key file can read the inbox. Anyone with a valid signed read link can also read mail while that link is valid. Email contents are stored on our servers for 24 hours.
Emails expire after 24 hours by default. Exporting your address saves its access key, not the messages, and does not extend their retention.
Choose Export email address to save a file, then use Import email address to open it later. Generating a new address replaces the address in this tab. It does not revoke the previous address. Without its exported file, you may lose access when the tab closes.
Choose an agent below the inbox, or open Connect for the native instructions, SDK, and MCP setup. Agents generate and keep their own key. Opening an agent does not share the address or key from this tab.
