Temporary Email for Developers
The developer story is the strongest case for disposable email: exercising a verification flow end to end without polluting a real mailbox.
The shape of the API
Create an inbox, then poll or fetch its messages. Each call is JSON in and JSON out with a consistent envelope. Inbox operations authenticate with the inbox token as a bearer credential, so a test cannot read an inbox it did not create.
Why tokens beat address-based lookup for tests
An address-based API means any process that can guess an address can read its mail, which in a shared CI environment is a genuine risk. A token issued at creation keeps test inboxes isolated from each other by construction.
Handling waiting in tests
Poll with a bounded backoff rather than a fixed sleep. Ask for the message list, look for a message matching your subject or sender, and fail the test after a deadline so a delivery problem surfaces as a clear timeout rather than a flaky pass.
Cleanup matters
Delete the inbox when the test finishes. Disposable or not, an inbox left behind occupies rows and its messages count against retention. Deleting it also proves your test is not accidentally relying on state from a previous run.
