Domain Health

A domain health check reviews everything a domain needs for working DNS and email in one pass: nameservers, MX, SPF, DKIM, DMARC, blocklists, and SMTP. This tool runs those checks together and grades the domain, with each problem listed and explained.

When to use this: You are taking over a domain, onboarding a client, or want one overall check before digging into details.

FAQ

How is the score calculated?
Points for working SPF, DKIM and DMARC, policy strength, reverse DNS, TLS and a clean blacklist record, the same score as the ProbeKit badge.
Can I track it over time?
Yes. A Domain Health monitor re-runs it daily and alerts on drops.
