3. How Waterfall Logic Saves You Money
Email Finder Waterfall
LeadEngine (Free) tries first.
If nothing found, we try the next finder on your list.
The first finder that returns a valid address wins; later finders do not run, so you pay only once.
Email Validation Waterfall
We validate every new address with our free validator (if selected).
Only addresses marked invalid flow to paid validators or catch-all scorers—again, charged solely when they run.
Research & Cleaner Waterfalls
Similar logic applies: paid scrapers, LinkedIn lookups, or AI clean-ups trigger only if earlier (free) steps can’t deliver.
Each step bills either one plan credit (if internal) or a cash charge from your metered balance (if external).
4. Metered Balance—Real Cash, Real Clarity
What | What How it works |
Auto-top-up | When the balance falls below $10, we’ll refill with the amount you set ($20 minimum). |
Live ledger | Every 3rd-party charge posts instantly—no guessing games. |
Example:
LeadEngine validates 1,000 emails → $0
LeadMagic validates 100 invalid emails → $0.10
ZeroBounce validates 50 invalids → 30 × $0.009 = $0.45
LeadEngine finds 400 emails → $0
LeadMagic finds 200 emails LeadEngine couldn’t → $4
FindyMail finds 100 emails LeadMagic couldn’t → $3
LeadMagic LinkedIn Profile scrape 200 profiles → $4
Firecrawl scraped 1000 web pages → $2
AI First & Last Name clean ran on 1000 leads → $0.50
AI Job Title clean ran on 1000 leads → $0.50
AI Company Name clean ran on 1000 leads → $0.50
Total debit: $15.05 against your metered balance.
