What it shows
- Authentication results: SPF, DKIM (including multiple signatures), DMARC, and the ARC chain, parsed from the receiving server's Authentication-Results.
- Sender alignment: compares the header From and envelope From at the organizational-domain level (Public Suffix List based), and flags display-name spoofing and Reply-To mismatches.
- Delivery route: the path from Received headers with internal/external IP classification and per-hop TLS status.
- Link safety: four-tier analysis (critical / suspicious / untrusted / privacy) covering deceptive link text, dangerous URI schemes, embedded forms, IP/IDN/shortener links, all-external and main-CTA analysis, and tracking pixels.
- Authentication strength: warns about fixable weaknesses such as sub-2048-bit DKIM keys, rsa-sha1, partial body signing, and DMARC p=none / sp=none / pct<100.
Security-first verdicts
The verdict is deliberately strict: a result is shown as green only when it is genuinely safe and nothing the sender or recipient could change would improve it. Anything fixable by the domain administrator, or resolvable by the recipient (by trusting a domain), is flagged.
