Legal, medical, and financial professionals handle privileged information daily. Your email lists contain client names and contact details that should never touch a third-party server.
When you upload client email addresses to a cloud service, you're sharing privileged information with a third party. In regulated industries, this creates real compliance risk.
BounceBuster runs as a desktop application on your computer. Your email lists are read from local files, validated locally, and results are written to local files. No data is uploaded anywhere.
Download, install, use. No sign-up, no credentials, no vendor relationship to manage. Your IT and compliance teams will appreciate the simplicity.
The only network activity is DNS and MX record lookups (e.g., "does example.com have mail servers?"). Individual email addresses are never sent over the network.
After the first validation, domain results are cached. Re-validating lists with the same domains works without any network access at all.
No BAA needed. No DPA. No vendor risk assessment. No security questionnaire. Just install and use.
No per-email fees. No monthly subscriptions. No usage tracking.
Free tier available: 500 emails/month with all features.
Download BounceBuster and validate email lists without any data leaving your machine. No compliance paperwork, no vendor risk.
