Check your domain for DMARC, SPF, MX, DKIM, BIMI, TLS-RPT, MTA-STS, and other email security records.
How It Works
Domain Scan
The tool queries public DNS servers then parses the relevant email authentication records. The results are then fed into a policy engine that highlights broken syntax, weak policy, and missing protections.
- Public DNS lookup
- The checker reads the public DNS records that mailbox providers can see for the domain.
- Authentication analysis
- DMARC, SPF, DKIM, BIMI, TLS-RPT, and MTA-STS records are evaluated for syntax, coverage, and policy quality.
- Actionable issues
- The results highlight missing protections, risky settings, and misconfigurations that affect deliverability and spoofing resistance.
Issue Detection
What issues does it scan for?
The checker looks for the failures that usually block DMARC enforcement, reduce deliverability, or leave gaps in your sender authentication setup.
