How the scoring works

Pattern generation

Up to 30 patterns per lead ranked by global frequency (firstname.lastname, flastname, etc.)

DNS MX validation

If the domain has no MX records, score drops to ≤5. Results cached 60 min.

Name quality

Compound names and surnames generate more specific patterns with higher specificity scores.

Honest scoring

Max score 97. Without SMTP probing we never claim certainty — use as probability, not fact.
