About

IntoDNS.ai is a DNS and email security scanner that runs deterministic checks against a domain and returns evidence for SPF, DKIM, DMARC, DNSSEC, MTA-STS, BIMI, FCrDNS, blacklists, and selected web security signals. The public scan flow produces readable findings, remediation guidance, and AI-assisted explanations where available.

The service is aimed at developers and operators who need a free domain-level diagnostic workflow rather than a generic toolbox. The pricing page states that all features are free forever, with no account required for scans, and that a free account adds nightly monitoring, scan history, saved domains, email fix digests, and CSP monitoring.

This free tier is perpetual and has no usage cap, so it’s effectively worth the full price of a comparable paid scanner rather than a discounted teaser. The only meaningful limitation is that some monitoring and digest features require a free account, but the core scanning and public API access remain available without a credit card, so the practical value is very high.

What's included in the free tier

  • Nightly domain monitoring with alerts when DNS or email configuration changes.
  • Scan history and dashboard for saved scan results.
  • Save favorite domains for quick access.
  • Email fix digests with top issues and recommended next steps.
  • CSP Monitor for collecting real violation reports and enforcing a strict CSP.
