The DKIM Record Checker is a free online tool available on AllToolHub that fetches and validates DKIM records for any domain. DKIM allows email senders to digitally sign their messages, enabling receivers to verify that the email was not tampered with and truly came from the claimed domain.
Enter a domain name and a DKIM selector, then click Check DKIM. The tool queries SELECTOR._domainkey.DOMAIN TXT records via Google DNS API. It parses DKIM tags (v, k, p, t), estimates key length, and provides security assessment. Quick selector buttons are provided for common email services.
DKIM (DomainKeys Identified Mail) is an email authentication method that allows senders to digitally sign their emails. Receivers can verify the signature to ensure the email was not altered in transit.
A DKIM selector is a string used to locate the DKIM public key in DNS. Different email services use different selectors, e.g., 'google' for Google Workspace, 'selector1' for Microsoft 365.
Check your email service documentation, or look at the DKIM-Signature header in a sent email. The 's=' tag contains your selector value.
