About the SPF check

SPF lists the servers allowed to send as your domain. A missing record, a second record, or more than 10 lookups all make it fail, and failing SPF is one of the first things Gmail and Outlook check.

Need a new record? The SPF generator builds one from the services you use.

Fix it, then keep it fixed
