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.
- DNS scans and propagation evidence

Free Tier Value
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.
