How does SPF Flattening work?

SPF Flattening Simplifies the SPF Record

MxToolbox SPF Flattening works by rewriting your SPF record. If you have more than 10 lookups included in your SPF record, the later lookups will not be executed, leaving some of your legitimate email senders to bounce. MxToolbox SPF Flattening:

  • Reviews the Verified Email Sources and manually added IP addresses currently in the SPF record.
  • Traverses all the email senders included in your SPF record to generate a complete record of all needed IP ranges.
  • Removes duplicate senders.
  • Consolidates overlapping IP ranges.
  • Crafts a compliant SPF record that covers all Verified Senders.
  • Monitors for new email senders and automatically makes suggestions to include them in your SPF record.

Our SPF Flattening is automatic and adaptive, enabling you to specify new Verified Email Sources and have a new SPF record almost instantaneously.
