What is DKIM (DomainKeys Identified Mail)?

An email authentication technique that allows the receiver to check that an email was indeed sent and authorized by the owner of that domain.

Detailed Explanation

DKIM adds a cryptographic signature to your emails. This signature is linked to a specific domain name using a private key. The receiving email server uses the public key (published in your domain's DNS records) to verify the signature. This ensures that the email was not altered in transit and confirms the sender's identity, building trust with inbox providers like Gmail and Outlook.
