- Visible issue counts before any payment step
- Enough proof to decide whether the list needs cleanup
What the buyer pays for
- Full cleaned CSV unlock for that exact batch
- Normalized fields plus issue codes
- Keep, review, or remove guidance for every row
Best Fit
Built for teams that need a cleaner CSV this week, not a bigger software stack.
Best for
Lead gen agencies, recruiters, and SDR teams that already have a CSV and need to spot obvious quality problems before handoff.
Not for
Huge managed data operations, deep enrichment pipelines, or teams expecting a multi-user SaaS platform in version 1.
Agency Pain
Bad rows waste sending volume before outreach even starts.
What goes wrong
Invalid emails waste volume, duplicates create confusion, and weak domains make the finished list feel unreliable before a rep sends a single message.
What this fixes
The buyer gets a visible QA pass, then a cleaned CSV they can review and deliver without doing the first cleanup sweep by hand.
Free preview
Counts, flagged rows, and enough visible damage to justify whether the batch needs a paid cleanup step.
Paid unlock
A full cleaned CSV with normalized fields, issue codes, duplicate status, and keep-or-remove guidance for each row.
Simple Buyer Flow
From messy CSV to cleaner handoff in three steps.
01 Load a sample
Paste a lead CSV or upload one directly into the tool.
02 Preview the damage
Surface invalid emails, risky inboxes, weak domains, and duplicates immediately.
03 Unlock the export
Pay once through Stripe and download the cleaned CSV after verification.
Version 1 Scope
This is intentionally narrow: one CSV in, one cleaned CSV out.
What version 1 does
Preview list quality, show the damage clearly, take a one-off payment, and release a cleaned CSV without manual intervention.
What comes later
Larger batches, reusable accounts, and more automation can come later. Right now ListSift only promises the live flow it already completes.
