SPF Lookup Analyzer
Count your SPF DNS lookups against the RFC 10-limit. See which includes are costing you and spot the unused services blowing your budget.
What We Check
- ✓DNS lookup count Against the RFC 7208 10-lookup limit
- ✓Recursive expansion Every include, redirect, and nested lookup
- ✓Void & broken lookups Mechanisms that resolve to nothing
- ✓Flatten candidates Which services are costing you the most
Why It Matters
SPF has a hard limit of 10 DNS lookups. Cross it and receivers return permerror, which silently breaks SPF for legitimate mail. Most domains hit the limit because old vendors were never removed.
Over the limit and not sure what to cut?
We help companies untangle SPF records, flatten where it makes sense, and audit which vendors still deserve to be there.
