About DKIM Records

The DKIM (DomainKeys Identified Mail) record lookup tool is a diagnostic tool that searches for and displays DKIM records that provide email authentication for a domain. This test will find the DKIM record for the queried domain name and selector, display the record, and provide important information about email security.

DKIM records use cryptographic signatures to authenticate the sender of an email. This verifies that the email actually originated from the stated domain and prevents email forgery. DKIM, together with SPF and DMARC, is one of the foundations of email security.

Benefits of a DKIM Record

  • Email Authentication

    Proves your emails really come from your domain.

  • Cryptographic Security

    Provides secure signing with RSA or Ed25519 keys.

  • Spam Prevention

    Reduces the risk of your emails landing in the spam folder.

  • Brand Protection

    Prevents phishing attacks and protects brand reputation.
