An SPF record is a type of Domain Name System (DNS) record that identifies which mail servers are authorized to send email on behalf of your domain. SPF records help to prevent email spoofing by verifying that the email message is coming from a legitimate source. When a mail server receives an email, the mail server can check the SPF record of the domain to verify that the email is coming from an authorized source. If the email is not coming from an authorized source, the mail server can reject the email or mark it as spam.

With Skysnag, you can easily manage Poppulo’s SPF records without having to go to your DNS. This allows Poppulo’s SPF record to propagate instantly, and autonomously always pass SPF alignment.
