FreeBulkEmailVerifier Desktop
A Windows application for people who verify email lists regularly and want it running locally, with history and export built in.
What you get
Local bulk verification
Verify large lists directly on your PC, with adjustable concurrency and timeouts.
CSV / XLSX / JSON export
Export all results, or filter by status first — valid only, disposable only, and more.
History & logs
Every verification is saved locally so you can look back without re-running anything.
Evidence-based results
The same honest VALID / VALID (ESTIMATED) / UNKNOWN / INVALID / ACCEPT-ALL / DISPOSABLE model as the free web tool — no inflated accuracy claims.
Who it's for
Freelancers, small marketing teams, and anyone who cleans email lists often enough that the free web tool's 50-per-batch / 100-per-day limits get in the way, and who wants verification running locally rather than through a browser.
How licensing works
Each license activates on a limited number of devices, verified online with a short offline grace period if the license server is briefly unreachable — so you're never locked out just because your internet dropped. Full activation status, expiration, and device count are shown right in the app.

FAQ
Does this work on Mac or Linux?
Currently Windows only.
Is there a batch size limit?
The desktop app processes larger batches than the free web tool; exact limits depend on your license tier.
What happens if I lose internet access?
The app keeps working during a short offline grace period using your last successful activation. The license server remains the source of truth once you're back online.
Can I move my license to a new PC?
Yes — deactivate the device in the app (or contact support) to free up the slot, then activate on the new machine.
