What is DKIM Checker?
The DKIM checker verifies DomainKeys Identified Mail records for your domain. DKIM uses cryptographic signatures to authenticate email messages, proving they haven't been altered in transit. Validating DKIM configuration ensures your emails pass authentication checks and reach recipients' inboxes.
