How Automatic SPF Flattening Works in 3 Steps
From a quick SPF audit to hands-off flattening - no manual DNS lookups or spreadsheet tracking.
Add your domain
Start your free trial, create an organisation, and add your domain with the same SPF includes you use today. spFlat! resolves and flattens them for you.
Publish one DNS update
Copy the recommended SPF record into your DNS. spFlat! monitors provider IP changes and keeps your flattened record updated 24/7.
Before & After: Bypassing the 10 DNS Lookup Ceiling
Your SPF record might look like this, with multiple includes that can exceed the 10 DNS lookup limit:
spFlat! converts it to a flat record with direct IP addresses, using only 1 DNS lookup:
Before: Complex SPF Records
spf.txt
$ SPF record
v=spf1
include:_spf.google.com
include:spf.protection.outlook.com
include:mailgun.org ~all
Flattened to 1 lookup
After: Flattened SPF Records
spf-flat.txt
$ flattened
v=spf1
ip4:209.85.128.0/17
ip4:40.92.0.0/15
ip6:2606:4700::/32 ~all
