Using Temporary Email for QA & End-to-End Testing

Testing email flows is notoriously painful. Real mailboxes are slow, shared, and flaky. Disposable email with an API fixes that.

The pattern

1. Your test calls the API to create a fresh inbox and gets back an address + token.
2. The test registers a user with that address.
3. The test polls (or receives a webhook) for the verification email.
4. It extracts the confirmation link or OTP code and continues the flow.

Why it beats a shared mailbox

Each test run gets an isolated inbox, so parallel runs never collide. Catch-all domains mean you can encode the test ID right into the address for easy correlation.
