How it works

From API call to delivered JSON in seconds

No MIME parsing, no inbox UI. Create an address, receive mail, read it as data.

Create an inbox

Spin up a disposable address with one API call. Random addresses, custom slugs, or catch-alls on your domain.

Receive the email

Mail lands at the address and is parsed instantly — sender, subject, body, and attachments captured.

Get it as JSON

Receive a signed webhook the moment it arrives, or poll on your schedule. Clean JSON, ready to use.
