Validation for lists you legally can't upload.
Client contacts, patient records, and account holders can't be shipped to a third-party API on a whim. BounceBuster keeps regulated data inside your perimeter: validation happens locally, so the data never enters someone else's chain of custody.
Zero data exposure
Nothing is uploaded, so there is no third-party custody of privileged or protected information to account for.
Fits your compliance posture
No new processor to add to a BAA or DPA, no vendor security review to run. The data simply doesn't move.
Format, DNS & MX, all local
Full deliverability validation on regulated lists, without a single record crossing your network boundary.
$19 once, audit-friendly
A one-time desktop purchase, not a recurring cloud subscription with shifting terms and renewals.
Keep regulated data inside your perimeter.
Download BounceBuster and clean up to 600 emails free. No account, no data leaves your machine.
