SPF (Sender Policy Framework) is an established method for verifying which servers are authorized to send emails on behalf of a specific domain, such as yourcompany.com. It applies to the technical sender domain.
For newsletters sent via APSIS, SPF is already configured by default. However, certain types of emails—such as reports or opt-in confirmation messages—may use your own domain as the technical sender. In these cases, we recommend adding APSIS to your SPF record:
include:_spf.anpdm.com
If you use multiple mail servers for sending and receiving emails, all of them should be included in your SPF record.
Example of an SPF record:
v=spf1 mx include:_spf.anpdm.com a:mail.yourcompany.com ip4:00.000.00.000 -all
Note!
SPF is not the same as SPF alignment. SPF alignment is used for DMARC authentication and is not required if your domain is DKIM-signed by APSIS.
