Disposable inbox API
MailboxTemp exposes a simple disposable inbox API so engineers can create inboxes and read incoming mail from code — ideal for end-to-end signup tests, QA pipelines, and any flow that needs to assert on a real email or verification code.
What you can build with the disposable inbox API
Automate the parts of testing that usually require a human checking an inbox: register a user against a fresh disposable address, poll for the activation message, extract the one-time code, and assert the flow end to end — all without a shared team mailbox.
Typical workflow
- Create an inbox via the API and get back its address.
- Drive your signup or password-reset flow using that address.
- Fetch the inbox messages; the OTP code is parsed for you.
- Assert and tear down — inboxes expire automatically.
Why MailboxTemp
- No shared-mailbox bottlenecks in CI.
- Real-time message delivery.
- One-time codes extracted automatically.
- Inboxes self-clean, so tests stay isolated.
