How SPF Flattening Works
Before: Complex SPF Records
Your SPF record might look like this, with multiple includes that can exceed the 10 DNS lookup limit:
v=spf1 include:_spf.google.com include:spf.protection.outlook.com include:mailgun.org ~allAfter: Flattened SPF Records
spFlat! converts it to a flat record with direct IP addresses, using only 1 DNS lookup:
v=spf1 ip4:209.85.128.0/17 ip4:209.85.128.0/17 ip6:2606:4700::/32 ~allAutomatically updated 24/7 as email providers change their IP ranges
