Email Risk Scoring for Fraud Prevention

An email address is one of the few data points every customer hands over at onboarding and checkout, and it carries a long digital history. This guide explains how email risk scoring works — domain age, breach exposure, social and commercial footprint, velocity and linkage signals — and how those signals expose synthetic identities, account takeover attempts and first-party fraud. It also shows where in the funnel to apply scoring so good customers pass untouched, based on LexisNexis Risk Solutions Emailage, the email risk scoring product we deploy for banks, lenders and merchants.

Frequently asked questions

How does email risk scoring work?
It assesses signals such as domain age, breach exposure, digital and commercial footprint, velocity and linkage to known fraud, returning a risk score in real time.
Does it add friction for genuine customers?

Account opening, login and checkout are the highest-value points. The guide explains how to sequence it with device and behavioural signals.
