DKIM or DomainKeys Identified Mail is an email authentication protocol that enables the email receivers to check whether or not an email was sent and authorized by the domain owner. Our DKIM Record Checker verifies the existence and validity of your domain’s DKIM record.
Working together with SPF and DMARC, DKIM allows organizations to authenticate emails, safeguarding their outbound email traffic. Correct implementation and configuration of a DKIM record is essential for ensuring the security of your domain and keeping spoofers at bay. This DKIM record lookup tool enables you to find the DKIM record for your domain and check its validity.
When you’ve implemented the DKIM record, the sending server signs all your outbound emails with a unique key. This key includes the body and various important headers like To, From, the date and the subject. Also known as a signature, this key is added to the emails as an extra header, allowing receiving mail servers to verify it and authenticate the emails.
There is a public part of this key, which is published in the DNS. The receiving mail servers can use this public key and the signature in the email to verify whether or not the email was modified after it was sent.Get 7-Day DMARC Free Trial
