What is DKIM?
DKIM (DomainKeys Identified Mail) adds a digital signature to your emails, allowing receiving servers to verify that the email hasn't been modified in transit and truly comes from your domain.
How DKIM Works
Your email server signs outgoing emails with a private key. The corresponding public key is published as a DNS TXT record. Receiving servers use the public key to verify the signature.
