Verification Accuracy
NeverBounce uses standard SMTP verification alongside supplementary checks. The problem: Gmail, Outlook, Yahoo, and other major providers have deliberately made SMTP-level verification unreliable — responding positively to probes even when the mailbox doesn't exist.
Zilch Bounce's proprietary deep verification engine takes a fundamentally different approach, confirming mailbox existence directly at the source without delivering any email. This translates to fewer false positives — especially for the high-volume providers where standard tools fall short.
Privacy & Data Control
NeverBounce requires you to upload your full email list to their servers. Your data travels over the internet, sits in their infrastructure during processing, and is subject to their privacy policy and data retention practices.
With Zilch Bounce, your list never leaves your PC. Verification happens locally through your own connection. There is no data upload, no third-party retention, and no dependency on NeverBounce's uptime for your list to be processed.
