DKIM

DKIM

DKIM, which stands for Domain Keys Identified Mail, is an email authentication protocol that uses cryptographic signatures to verify that a message’s content hasn’t been altered during transit. When a message is sent, the sending server adds a DKIM signature header that includes an encrypted hash of the message body and certain headers. Receiving servers use the public key published in the sender’s DNS to decrypt the signature and confirm that the message is intact and that it was authorized by the sending domain.  

DKIM helps protect recipients from spoofing and tampering, and plays a key role in determining sender reputation when used alongside SPF and DMARC.  

Set up email authentication protocols like SPF, DKIM, DMARC, and BIMI to protect your brand. These protocols help inbox providers validate that your messages are authentic, unaltered, and aligned with your domain, boosting credibility.
