Stop criminals
spoofing your domain.

OuterMark walks your domain safely from its first report to full enforcement (p=reject), so no one can send email pretending to be you. Set up in minutes, no engineer call required.

• See every system sending email as you, classified for you.
• Copy-paste DNS records, with one-click guidance.
• We move you to enforcement only when it's safe, never breaking real mail.
• Monthly PDF reports for your board, auditor or insurer.
