What does a domain health check test?

It checks your SPF, DKIM and DMARC records, your MX (mail server) records, and your domain registration status, then combines them into a single 0–100 score with specific recommendations.

Yes. The one-off check is completely free with no signup. Continuous monitoring and alerts across many domains are part of the paid plan.

Why do my emails go to spam?

The most common causes are a missing or misconfigured SPF, DKIM or DMARC record. Run the check above to see which of these needs fixing on your domain.

Domain & Email Health Check

Check any domain's email security and health in one click. Free, no signup.

By using this free tool you agree to our Terms and Privacy Policy.

DomainHealthPro runs an instant health check on any domain: it verifies your SPF, DKIM and DMARC email-authentication records, confirms your mail servers (MX) resolve, and reports on your domain registration — then scores it all out of 100 with plain-English fixes.

Since 2024, Google, Yahoo and Microsoft require bulk senders to have DMARC in place. Misconfigured email authentication is the number-one reason legitimate email lands in spam and the easiest way for scammers to spoof your domain. This free tool shows you exactly where you stand in seconds.

Managing domains for clients? The paid version continuously monitors every domain and alerts you the moment DNS records change, before SSL certificates expire, or if DMARC breaks — with white-label reports you can send under your own brand.

What your report looks like

Every check scored and explained in plain English — instant in your browser for free scans, and by email plus shareable white-label report for monitored domains.
