About the checker
Is the DNS check free and private?
Yes. It only reads public DNS records, the same ones anyone can look up. We don’t store the domains you check.
Why does the check still fail after I added a record?
DNS changes can take time to reach every resolver. Many show up within minutes, but some take hours. Wait a bit and run the check again.
Why do I need to choose my email provider?
Correct values depend on the provider. Choosing it lets us confirm your MX, SPF and DKIM actually point to it, not just that some record exists.
