SPF Flattening
Overcome the 10 DNS lookup limit with our hosted SPF solution. Automatic flattening and IP resolution keeps your SPF record compliant and your emails delivering.
The 10 DNS Lookup Limit
SPF records are limited to 10 DNS lookups. Everyinclude:andredirect=counts against this limit.
Modern organizations use dozens of email services: Google Workspace, Microsoft 365, Salesforce, HubSpot, Mailchimp, SendGrid, and more. Each adds lookups to your SPF record.
When you exceed 10 lookups, your SPF record fails validation entirely—causing email rejection.
SPF Flattening with MimeProtect
We resolve all your includes and redirects into a single, optimized SPF record with just one lookup.
Automatic Flattening
We resolve all nested includes into direct IP addresses, reducing your lookup count to just 1.
Auto-Updates
When providers change their IPs, we detect it and update your flattened record automatically.
