Frequently asked questions

Common questions about uploads, validation quality, and how Bounce Protect handles data.

What file types can I upload?

Bounce Protect supports CSV uploads for validation workflows. CSV is the recommended format for predictable column mapping and clean exports.

How accurate is validation?

Validation combines syntax checks, domain quality signals, disposable provider detection, and role-based pattern checks to provide practical status labels for campaign preparation.

Do you store uploaded data?

Uploaded files and parsed validation data are stored so you can review results and export clean records from your dashboard history.

How long is data retained?

Data is retained to support historical reporting and re-download workflows. Teams can request deletion for account-level cleanup requirements.

Can I upload Excel files?

Direct Excel uploads are not currently supported. Export your workbook as a CSV file and upload that file to run validation.
