DKIM verifies that the domain owner authorized the email that the sender sent from that domain.

With DomainKeys Identified Mail (DKIM) Zivver can take responsibility for a message. In this process, a recipient can verify that message. Zivver generates a public key in the Zivver DNS settings in the admin portal. Then, Zivver signs the emails with a private key so that the receiving mail servers can verify the email.
