How do I setup my DKIM/SPF?
Before you send emails from your own domain, we ask that you add 3 CNAME records that allow us to sign the emails we send on your behalf, such as review invitations.
Our domain authentication uses a DKIM method which automatically sets up the SPF for you as you. You can plug your domain into this tool to verify the SPF record: https://mxtoolbox.com/SuperTool.aspx?action=spf
