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

PartnerStack delivers emails through our email processing partner at Twillio SendGrid.

SendGrid provides each PartnerStack customer DNS records that allow PartnerStack to deliver emails on behalf of your domain.

Follow these steps to authenticate your domain:

1. Contact PartnerStack Support

Contact the PartnerStack support team at [email protected], including "DMARC" and your domain host (e.g. Google Domains, GoDaddy, Hover, etc) in your email.

PartnerStack support will provide you with three CNAME records to add to your domain. If your domain is managed on GoDaddy, please note their formatting requirements.

2. Add CNAME records to your DNS

Add the three CNAME records to your domain's DNS records, as given to you by Support. You may need to contact a technical resource at your company to have these records added.

Each CNAME points to securely stored, internally managed records.

3. Validate CNAME records

Let PartnerStack support know that the records have been added. Support will validate that the addition was successful, and assist you with troubleshooting if it was not.

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