Frequently Asked Questions
Common questions about DMARC lookups and domain checking
How do I check my DMARC record?
Enter your domain name in our free tool above. We'll automatically query your DNS at _dmarc.yourdomain.com and show your DMARC, SPF, and DKIM records with a security grade and recommendations.
Why does my domain have no DMARC record?
No DMARC record means you haven't published a DMARC policy in DNS. This leaves your domain vulnerable to spoofing. Use our DMARC Policy Generator to create a record, then publish it at _dmarc.yourdomain.com.
What's the difference between DMARC, SPF, and DKIM?
SPF lists authorized sending IPs, DKIM adds cryptographic signatures, and DMARC tells receivers what to do when authentication fails. Our checker validates all three simultaneously.
