- Review p, rua, ruf, pct, and alignment-related tags before rollout.

Steps Run order and common questions
- Enter domain for a bounded Convurter server lookup.
- Run the inspection lookup and review the point-in-time response.
- Review the dmarc-report result, then copy or download it if the workbench offers that action.
- Use related retained tools for validation, cleanup, conversion, or the next workflow step.
Use it well Examples, checks, limits, and recovery paths
Bad inputs
- Expecting it to verify DKIM signing or mailbox placement.
- Treating p=none as wrong when monitoring is intentional.
- Expecting the report to prevent spoofing by itself.
Output checklist
- Confirm the record is at _dmarc for the domain.
- Review policy and report destinations.
- Compare results with SPF, DKIM setup, and sender-platform instructions.
Failure modes
- Missing or multiple DMARC records need DNS review.
- Report destinations may require external verification.
- DMARC policy does not by itself prove every sender is aligned.
Runtime limits
- Server lookup.
- Public DNS record parsing only.
- No mailbox-provider placement or anti-spoof guarantee.
