How do I add a SPF record?

It is not required to include Prefinery in your own custom SPF record.

Years ago when email standards were being formed, email providers used the SPF records of the From/Sender address’ domain to check for alignment. This meant that it was necessary for Prefinery users to add a custom SPF record to their DNS in order to pass SPF alignment. This has since changed, and email providers no longer check the From field’s domain when evaluating SPF and determining the results.

The Return-Path domain is now used by receiving email domains to check for SPF alignment. This means your emails sent through Prefinery will always pass SPF by default, without any necessary action on your end, since the Return-Path of all emails sent through Prefinery already includes our outbound sending IPs and SPF record.

In order to correctly set up the Return-Path, visit the Email > Senders page in your project and click the View Verification Instructions next to your domain. The instructions will explain how to add configure the Return-Path by adding a CNAME record to your DNS.
