Coverage
Watch SPF, DMARC, and MX in one monitor
Keep the full sender-domain posture in one place so the cause of drift is obvious the moment health changes.
Verification
Run immediately after DNS edits or before a send
Use on-demand checks to confirm the domain state you expect before traffic ramps up or registrar changes land.
Response
Route failures to the team that owns DNS
Push degraded findings into the same channels ops, support, or platform teams already use to handle incidents.
