Example inputs
example.comgmail.comCommon issues and fixes
No SPF record
Domain has no SPF TXT record — email may fail DMARC or be marked as spam.
Too many DNS lookups
SPF allows max 10 DNS lookups. Use -all or flatten include chains.
Hard fail with typos
~all (softfail) is safer than -all during migration. Typo in mechanism = fail.
Recommended remediation
Add v=spf1 include:_spf.google.com ~all (example). Use SPF flattening if you exceed 10 lookups.
