Prepare your input
Build and check a DMARC DNS policy with clear tag explanations.
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
Produces a DNS TXT value and reviews supplied tags using RFC 7489 semantics. Does not publish DNS or prove SPF/DKIM alignment. External report destinations require separate authorization by the receiving domain; report addresses may expose aggregate metadata. Forensic reports are not enabled by the builder.
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.
