How to set up DMARC for Marketo in Valimail

Updated over a week ago

This article covers the SPF and DKIM authentication processes for Marketo and how are they 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 Marketo emails

1. Open your Marketo account as an administrator.

2. Go to the Admin section.

6. Once the DKIM key is added in Valimail Enforce, come back to Marketo, select your domain, and click Check DNS.

7. Once the DKIM key is validated, you will be ready to send authentication emails on behalf of your domain, using Marketo.

Note: The Marketo DNS check may not like the Valimail SPF Macro and display a warning. While Marketo will send in alignment, you may need to contact Marketo Support to have them override the SPF validation script in their UI. The SPF response will work correctly and you can verify this by following the instructions found in this article: Valimail SPF Records.

Once you establish that Marketo is an authorized sender for your domain, you will need to add the service in your Enabled Senders.
