This article covers the SPF and DKIM authentication processes for Squarespace Email Campaigns 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.

Squarespace Email Campaigns does not send SPF aligned emails by default, so DKIM would be the best configuration option for this service.

1. Log in to your Squarespace account as and administrator.

2. From the Email Campaigns dashboard, click Settings, then click Sender Details. Find the details you want to update, then click Verify Domain.

The window that opens has two records you'll need to add to your DNS settings.

3. Add the CNAME DKIM key record to Valimail.

4. After the DKIM key is added in Valimail, come back to this Squarespace window and click on Authenticate Domain.
