DIAGNOSTIC PLAYBOOK
Run a weekly email health review
A weekly review should focus on changes and unresolved findings rather than repeatedly reading the same green checks. Pair DNS history with sending evidence and ownership to make the review actionable.
HealthCheck Email editorial team · · Examples are illustrative
How to investigate
- Compare the latest record set and health findings with the previous approved baseline.
- Review new sources, alignment changes and delivery issues by mail stream.
- Assign an owner and next evidence step to each meaningful difference, then close resolved items with verification.
What this looks like
ILLUSTRATIVE EXAMPLE
A new selector appears after an approved provider rotation. The review links it to the change record instead of escalating it as an unknown sender incident.
A mistake to avoid
A weekly review supplements alerts; it is not a substitute for responding to an active delivery failure when it occurs.
Keep the result in context
A monitoring routine needs an owner, a baseline and a response to a meaningful change. Keep the sender inventory and approved DNS configuration alongside incident notes. HealthCheck Email supplies checks, history and supported alerts; publishing DNS changes and administering mail systems remain with your team.
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.
