Email

What it entails

Email checks profile longevity and activity via first_seen and last_seen, flag never-seen or disposable addresses, validate format and MX records, classify provider type and free vs. paid accounts, and analyze user-portion randomness. They build a holistic maturity and legitimacy score for each address.

Why it works

Fraudsters spin up newly created, disposable, or invalid emails to evade linkage and detection. Randomized or stale addresses with poor deliverability are strong indicators of one-time scam setups.
