I built a free email-domain check for insurance agencies and the IT providers who support them. It reads public SPF and DMARC DNS records and creates a downloadable report with observations, unknowns and questions for the existing provider.

It is a one-time public DNS snapshot. It does not audit a mailbox, test DKIM signatures or message alignment, monitor changes, or assign a security score. A published record is not proof that an account is protected. No account or client-record upload is needed; the entered domain goes to the lookup service and its DNS resolver.

Prepared with AI assistance. Published by Cirlet, which also offers paid AI and cybersecurity help to agencies. This free utility is separate from that service; no customer results, security guarantee or vendor endorsement are claimed.
