Prepare your input
Review SPF mechanisms, IP ranges and DNS lookup limits.
Use the labeled working sample to see the accepted format. Replace it with your own input, select the relevant options, and run the tool. Supporting controls remain in the bounded editor window.
Understand the result
Static analysis only: does not evaluate a sender or query included domains. Counts DNS-triggering terms on every supplied include/redirect path; missing references and macros make the total incomplete. Cycles, +all, unreachable mechanisms, duplicate modifiers and syntax issues are reported. a/mx/ptr can involve additional DNS work; no deliverability verdict.
Export deliberately
Record exports contain the complete selected dataset; reports summarize up to 100 records. Artifacts contain the actual generated configuration, sanitized capture or compressed bytes. Review configuration before publishing it.
Input stays in browser memory. No remote page fetching, account access or file upload is performed.
