Domain Health
Review DNS and email configuration together.
A domain health check pulls the delegation, addressing and mail records for one domain and presents them side by side, so you can see whether DNS and email agree with each other instead of checking each record in isolation.

How Domain Health works
What it does
Review DNS and email configuration together.
What you get
A combined review of common DNS and email records.
Live data sources
The target is sent to a network provider. Results include their source; timeouts and unavailable data are clearly marked.
What if a check cannot finish?
Confirm your input and try again. A timeout, blocked request, or unavailable provider is not proof that a domain is broken. Internet measurements and third-party services have limits.
Domain Health — frequently asked questions
Which records are included?
Nameservers and address records for reachability, plus MX and the SPF, DKIM and DMARC records that govern mail. They are shown together because a mail problem is usually a disagreement between them.
Is a clean report a guarantee?
No. It means the published records look consistent. Deliverability also depends on sending reputation, content filtering and the receiving provider's own rules.
How often should I run this?
After any DNS, host or mail provider change, and periodically if you send mail — records drift when a provider is added and the old include: is left behind.
