DNS authentication diagnostic
DKIM record checker
Enter a domain and DKIM selector to look up the public key record at selector._domainkey.domain.
What is a DKIM selector?
DKIM records are stored beneath a selector-specific DNS name. For example, a selector named google on example.com is published at google._domainkey.example.com. The selector is normally visible in the DKIM-Signature header of a signed email.
What this checker does
EmailValidly performs a DNS TXT lookup for the exact selector and domain you provide. It reports the published record if one is available. It does not infer or brute-force selectors.
