How to read a Domain Health report
What the score means, how categories are weighted and what to fix first.
The Domain Health report runs every StatusDNS check for a domain and groups the results into Blacklist, Mail Server, Web Server, DNS and Registration. Each check is an error (−15 points), warning (−5) or pass. The score starts at 100 and maps to a grade: A ≥ 90, B ≥ 80, C ≥ 65, D ≥ 50, F below.
What to fix first
Work through the Problems tab top-down: blacklist listings and missing DMARC/SPF affect delivery immediately; expiring certificates and domains become outages; DNS warnings are usually resilience improvements.
