How to set up DMARC for Optimizely (ex Episerver) in Valimail

Updated over a week ago

This article covers the SPF and DKIM authentication processes for Optimizely 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.

Configuring DKIM authentication for your Optimizely emails

To use a preferred domain, several DNS records must be created. The following configuration steps use the domain example.com.

Note: The domain t.example.com is the technical subdomain of example.com.

  1. Create a new A-RR entry to lead tracking links to the Optimizely tracking server

    • Domain: t.example.com

    • Value:

  2. Create a new MX-RR entry to lead technical responses (e.g. bounce messages) to the Optimizely email server.

    • Domain: t.example.com

    • Priority: 0

    • Value: mail.srv2.de.

  3. Create a new TXT-RR entry to authorizes all IP addresses used by the Optimizely email servers for your domain.

    • Domain: t.example.com

    • Value: v=spf1 include:spf.srv2.de -all

  4. Create a new CNAME-RR entry to authorize the subdomain and ensure compatibility.

    • Domain: mailing._domainkey.t.example.com

    • Value: dkim.srv2.de.

  5. Create a new CNAME-RR entry to authorizes the Optimizely servers to use your domain for sending emails via Optimizely Campaign.

    • Domain: mailing._domainkey.example.com

    • Value: dkim.srv2.de.

  6. Create a new TXT-RR entry to set a DMARC record to protect your domain from email spoofing.

  7. Optional: If you have domain management self-service enabled in your client, you will need to add a CNAME record for verification. (Replace VERIFICATION_CODE with the string displayed in Campaign UI, see Adding a domain in the User Guide)

    • Domain: VERIFICATION_CODE.t.example.com

    • Value: t.example.com.
