How do I verify a whole list?

Cet article est disponible uniquement en anglais.

1. Open Lists in your dashboard and upload a CSV, TXT or Excel (.xlsx) file, up to 60 MB and 1,000,000 rows.
2. We find the email column and remove duplicates for free.
3. Check the cost, then click Verify.
4. When the list is done we email you. Download the results as one file or by group (valid, risky, invalid), or download your original file with the results added as new columns.

Lists and results are deleted automatically 30 days after they finish.
