How the scoring works

①
Pattern generation

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

②
DNS MX validation

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

③
Name quality

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

④
Honest scoring

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