SPF Quick Guide

What is SPF record and how to configure it.

Sender Policy Framework (SPF) is a domain-based sender authentication that uses DNS records to check the policy of a sender’s domain. will provide a text string (the SFP record for your account) that you paste into the .TXT file of the DNS for any domains that appear in the From field of your messages. We will confirm, on request, that the change to the DNS was correctly made.

Another way to configure your SPF is to use DomainKeys Identified Mail (DKIM). DKIM is a method for associating a domain name with an email message, thereby allowing a person, role, or organization to claim some responsibility for the message. The association is set up by means of a digital signature, which can be validated by recipients. For more information about SPF and DKIM, or how to add both records to your domain DNS, please check out our SPF adding Guides.
