Automate Email Verification in Tests
Daniel Okoro · Security Writer, SecureTempMail 7 min read
Email verification is one of the hardest things to test reliably. An email API makes it deterministic.
The CI pattern
- Create a fresh inbox via the API and capture its address + token.
- Drive your sign-up flow with that address.
- Poll the inbox (or receive a webhook) for the verification message.
- Parse the link or OTP and complete the flow — then assert success.
Why it's reliable
Each run gets an isolated inbox, so parallel CI jobs never cross-contaminate. Catch-all domains let you embed a run ID in the address.
