Lead List QA
Show the damage before you pay to clean the list.
ListSift lets you paste a lead CSV, inspect invalid emails, weak domains, and duplicates, then pay once to unlock a cleaned export. Version 1 is a simple one-off buyer flow: no subscription, no sales call, no account setup.
Payment
Hosted by StripeCard details stay inside Stripe Checkout, not this app.
Output
Instant CSV releaseThe download unlocks only after the paid session is verified.
Interactive Tool
Run the live version-1 preview in the browser.
This uses the live ListSift preview flow and the same server-side hygiene rules that power the paid export.
Input CSV
Paste a lead list or load a UTF-8 CSV file to see what would make a buyer hesitate before delivery.
Version 1 rules
- Sample CSV loads automatically so the tool is usable on first visit.
- The free preview shows counts plus a flagged-row sample before checkout.
- This version is a one-off cleanup flow for the exact CSV you inspect here.
Preview Result
The preview should make the quality gap obvious enough that the paid export feels concrete, not speculative.
