DIAGNOSTIC PLAYBOOK
Onboard a client domain into email monitoring
Client onboarding needs technical baseline data and a clear division of responsibility. Establish who can publish DNS, who owns each sender and who responds when a check changes.
HealthCheck Email editorial team · · Examples are illustrative
How to investigate
- Confirm the domain scope and get the client's approved sender and DNS-owner inventory.
- Run baseline checks and record existing findings before attributing later changes to your service.
- Choose alert recipients and a response workflow, then review one sample incident together.
What this looks like
ILLUSTRATIVE EXAMPLE
An agency can detect a broken record but cannot edit the client's registrar account. Naming the DNS owner prevents the alert from stalling in the agency inbox.
A mistake to avoid
Do not label every preexisting issue an incident caused by a new deployment. Save the baseline and change history.
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.
