How to use this tool well

  • Work with the real content or domain you plan to send from, so the findings match your live setup.
  • Treat every result as practical guidance. Automated checks reduce risk, but no tool can guarantee inbox placement.
  • Fix the highest-severity findings first, re-run the check, then move the improved version into a campaign.
