What the risk engine evaluates
0–100 risk score
Built from six weighted categories: email quality, domain, disposable, provider, deliverability, reputation.
Separate confidence value
Tracks how much real evidence backed the score — a fast-mode guess and a fully-verified result are never conflated.
Allow / review / block decision
A direct routing decision derived from the score band, not just a raw number to interpret yourself.
Explainable signals
Every point of the score traces to a named signal with severity, impact, and a plain-language description.
Context-aware weighting
Signup, B2B lead, CRM, marketplace, and payment contexts each weight specific signals differently.
Domain reputation & age
Composite reputation scoring and domain-age signals catch infrastructure risk, not just the address itself.

No. Spam scoring evaluates message content and sending reputation. This evaluates the address itself, independent of any message being sent.
No — it means several independent signals were present. It's evidence to weigh via your own decision routing, not a verdict.
Context multiplies specific signal weights before summing. A role-based address weighs far more in a B2B lead context than in a generic signup context.
Yes — every response includes the individual signals, their severity, and their point impact, so the score is always traceable to specific facts.
