Product
Verification that protects your provider budget
FirstPass sits between raw lists and paid verification calls. It screens what it can, normalizes provider responses, and gives your team clean results for action.
How it works
Four steps from raw list to verified export.
- 1
Bring in the list
Paste addresses, upload CSV or Excel, or connect Google Sheets. FirstPass keeps the workflow direct and repeatable.
- 2
Screen before spending
Syntax, MX records, disposable domains, cache, and catch-all signals reduce waste before your Reoon credits are used.
- 3
Verify with Reoon
Connect your Reoon API key. FirstPass runs power-mode verification and normalizes results into clean categories.
- 4
Deliver clean outputs
Export CSV, Excel, or JSON, or write status and score back to Google Sheets for immediate follow-up.
A disciplined verification pipeline
Syntax validation, MX lookup, disposable detection, catch-all signals, cache, format intelligence, and provider verification work together to reduce waste before paid checks run.
Controlled runs for large jobs
Queue large batches with daily caps and active hours. Pause, resume, and review completed work from the dashboard when verification needs to run over time.
