Before you copy

Confirm these details first:

  • Workspace/environment is correct.
  • Inbox has not expired or been deleted.
  • You are using the intended domain (pooled vs custom).

If needed, review domain pool guidance and custom domains.

Typical failure patterns

  • CI job uses an inbox from a previous run.
  • Address copied from staging while testing production-like flow.
  • Wrong recipient domain causes routing policy mismatch.
  • Team assumes alias behavior that the current test setup does not support.

Team best practices

  • Create one inbox per test run or worker.
  • Store inbox IDs in run metadata for traceability.
  • Assert sender/subject/link/OTP values, not only message existence.
  • Keep webhook events enabled for async delivery debugging.
