How scoring works
Simple, transparent rules — the exact weights live in js/qualify.js:
| Signal | Points |
|---|---|
| Corporate (non-free) email domain | +40 |
| Valid email syntax | +20 |
| Has a name | +15 |
| Has a company | +15 |
| Has a phone number | +10 |
| Disposable email domain | score 0 — Disqualified |
Buckets: Hot ≥ 70 · Warm 40–69 · Cold < 40 · Disqualified = disposable email.
