"result": "risky",
"score": 64,
"signals": ["mx_found", "free_email", "catch_all"]
}What drives confidence?
Syntax, domain health, disposable status, SMTP behavior, and history.
How should I read it?
Higher scores usually mean lower risk, but your own policy decides the cutoff.
Why a score is easier to use
A single score is easier to wire into product decisions than a long list of raw checks. It lets your app map email outcomes to simple actions such as accept, warn, review, or block.
What should affect the score
Score models usually combine syntax, MX, disposable status, role-based status, catch-all behavior, and optional SMTP results. The point is to make the decision explainable and consistent, not merely numeric.
