Live checks across seven email-security protocols, scored against measured internet baselines, with copy-paste fixes for every gap.
Public assessments are free forever.
No credit card. No account. No marketing emails.
Real-time adoption data from actual public domains, benchmarked against our own Top-1M study. Nothing sampled, nothing invented.
Published = present in DNS. Effective = configured to protect (enforced policy, not decoration). Scoring rules →
Everyone claims to have SPF and DMARC. The measured reality is far worse — these are the actual numbers.
Every domain gets a 0–100 score built from weighted, RFC-based checks. Domains that legitimately send no mail are scored on a dedicated Null-MX profile instead of being punished for missing mail infrastructure. The assessment engine and scoring methodology are open source, so every rule can be inspected and reproduced.
A score without a path forward is just bad news. Every SecLens assessment includes a full remediation pack: the exact DNS records to publish, the MTA-STS policy file to host, and a staged DMARC rollout plan — consolidated, copy-paste ready, and downloadable as a single file for your ticket or change request.
We do not invent testimonials. Every signal below is a product fact you can open, read, or reproduce.
Adoption and scores from domains actually assessed — nothing sampled, nothing invented.
Published baseline against one million domains — the benchmark behind the Pulse.
Every weight and check is documented. No black-box grade.
