Where Email Risk Radar differs
Transparent, named signals instead of a single proprietary score
Email Risk Radar returns every contributing signal by name, with its severity and point impact, rather than a single reputation number.
Context-aware weighting
Scoring adapts based on a context parameter (signup, B2B lead, marketplace, payment) rather than a single fixed evaluation.
Quota-based plans, not per-result credits
Email Risk Radar uses monthly quota plans plus an optional one-time bulk pass, rather than a purchased-credit-per-result model.
