DIAGNOSTIC PLAYBOOK
Password reset emails arrive too late
A delayed password reset may spend time in your application, sending queue or receiving system. Trace a single request end to end before assuming the destination's spam filter caused the delay.

How to investigate
- Record the request time, job creation, provider submission and message acceptance timestamps.
- Correlate the same transaction across application and mail logs without exposing reset tokens.
- Repair the stage with demonstrated delay and test that token lifetime remains usable after delivery.
What this looks like
ILLUSTRATIVE EXAMPLE
The application waits behind a large campaign queue before submitting reset messages. SMTP is fast once the provider receives them.
A mistake to avoid
Do not place reset tokens or full private message bodies into a shared incident note. Use safe identifiers and timings.
Keep the result in context
A successful handoff, a delivered event and an inbox placement are different observations. Record the receiving provider, send time, SMTP response and affected stream before comparing results. DNS fixes address authentication or routing; they cannot establish consent or guarantee placement.
Take the next step
Use the related check to gather evidence, then compare it with the affected message or service. Keep the result and time with your notes so a later change can be distinguished from the original problem.
