Tempmailboxes

Users can create a public mailbox instantly without signing up, with up to five public mailboxes available. These inboxes are shared with others who have saved access, so they are intended for messages users are comfortable leaving public. Free public messages are retained for seven days, while Plus messages are retained for 14 days; other retention periods depend on the plan.

For more private receiving, Pro and Developer plans offer account-owned mailboxes on premium or verified custom domains. Private messages are accessible to the account owner, and retention follows the selected paid plan. Mailboxes remain saved until removed, though anonymous access can be lost if browser storage is cleared. The service does not send, reply to, or forward email.

Developer plan features include an API for private mailboxes and an OTP event stream that monitors new messages for up to 60 seconds, returning code candidates with metadata and heuristic confidence. The service also provides API documentation and information about its privacy practices, plans, and terms.
