QA testing email service
MailboxTemp exposes a simple QA testing email service 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 QA testing email service
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.
Frequently asked questions

Are one-time codes available via the API?
Yes — detected OTP codes are included in the message data returned by the API.
Do inboxes need manual cleanup?
No. Inboxes expire and are purged automatically, keeping test runs isolated.
Is the QA testing email service free to try?
Yes, you can start for free. Higher-volume and longer-lived inboxes are available on the Pro plan.
