Domain reputation degrades quietly — a single bad campaign or a compromised neighbor on shared infrastructure is enough. Monitoring it continuously means you find out before customers and inbox providers do.
Pick the assets that matter — sending domains, checkout hosts, customer portals — and run the reputation + blacklist + SSL sequence on a schedule. Alert only on state changes; absolute scores generate noise.
Run through these steps in order. Each step links to the right diagnostic tool.
Sending behaviour, blacklist status, hosting reputation, age, content classification, and historical abuse reports.
Daily for revenue-critical domains, weekly for everything else. State changes matter more than absolute scores.
Pause new outbound activity, run the verification workflow, identify the trigger (new IP, content change, blacklist hit), and remediate before resuming volume.
Blacklist is binary and reactive. Reputation is a continuous score that often moves first.
