How the gate works
This tool grades a sending domain's email authentication against the 2024 bulk-sender rules. It scores 6 weighted controls into a 0–100 number — then a gate that can only make the verdict worse.
The 6 weighted controls
For a domain sending over 5,000/day, a hard authentication blocker — no DMARC policy, or no from-domain alignment — forces FAILING regardless of the score. That mail is being rejected at the SMTP level now.
Why: The domain sends in bulk with no DMARC policy — a hard authentication blocker — so it reads FAILING even though the six-control math lands at 76 (only AT RISK on a low-volume domain).
A high score didn’t save it. The score is context; the gate is the answer — and it names the one thing to fix first. Grades configuration, not your legal obligations. No guarantee of inbox placement.
