This article covers the SPF and DKIM authentication processes for Epsilon and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

To setup DKIM for your Epsilon emails, please contact the Epsilon support team, here.

They will then provide you with the necessary DKIM records.

NOTE: If you manage you domain in Valimail, you will need to add the DKIM key/s on your domain's configuration page in the Valimail platform.
