DIAGNOSTIC PLAYBOOK
Hand off email monitoring to another team
A monitoring handoff should transfer decisions and ownership, not just dashboard access. The receiving team needs enough context to distinguish expected changes from unresolved risks.

How to investigate
- Document domains, sender owners, DNS authority, alert routes and open findings.
- Review a past incident and walk through the new team's response responsibilities.
- Verify access and alert delivery with an approved test, then remove obsolete access through the normal account process.
What this looks like
ILLUSTRATIVE EXAMPLE
The old team leaves a webhook pointing at a retired channel. Monitoring continues to run, but nobody receives its actionable alerts.
A mistake to avoid
Do not place passwords or private signing keys in the handoff document. Use the organization's approved access-management process.
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.
