Email Validation
Understand how your domain receives email and protects against impersonation. Check MX, SPF, DKIM and DMARC in one place.
Find the selector in your email provider’s settings or the s= value of a message’s DKIM-Signature header. Without it, DKIM will be marked as not checked.
Results
These checks inspect published DNS records, not mailbox existence or message delivery. SPF authorization, DKIM signatures and DMARC alignment need an actual sender or signed message to verify. DMARC is checked at the exact domain entered; parent-domain policy inheritance is not evaluated. DNS changes may take time to appear.
