DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

Steps to Configure DKIM for NewZapp

To obtain your DKIM keys and enable DKIM authentication for your domains, contact NewZapp support team. You will receive a DKIM key pair from NewZapp support that will include:

1. A DKIM public key, which should be published in your public DNS.
2. A DKIM private key: used by NewZapp to sign your outgoing emails

The DKIM key pair can also be created using our free DKIM record generator tool if you are sending emails from your own servers as opposed to NewZapp
