This article covers the SPF and DKIM authentication processes for Zeta Global 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 Zeta Global emails, please contact the Zeta Global support team so they can help you with the DKIM implementation for your domain.

Zeta Global uses a 2048bit encryption on their DKIM key.
