FAQ
Is this free?
Yes, checking a domain is free and doesn't require an account.
Why didn't it find my DKIM record?
This tool checks common DKIM selectors (default, google, selector1, s1, and a dozen others). If your provider uses a custom selector, it won't show up here - that's a limitation of public DKIM checking, not a sign your DKIM is broken.
What does it mean if I have no DMARC record?
No DMARC record means nobody's enforcing anything if someone spoofs your domain - a real, common gap. Adding even a permissive p=none record with reporting turned on is a good first step.
