About Zero Bounce

You verify a single address or upload a list by CSV, paste or API, and every result comes with a clear reason and a confidence level. Checks include syntax, MX records and SMTP verification, catch-all detection that flags risky domains, spam-trap alerts, toxic domain flags and automatic suggestions for common typos.

Lists are deduplicated, and batch jobs show progress in real time, with signed webhooks, Zapier, Make and n8n for automation, and CSV export. Verification mode is chosen as lenient, balanced or strict, costing 1, 2 or 3 credits per email respectively, with unknown results, duplicates and cached results free. The service also lists retention controls and deletion endpoints for GDPR and shareable branded reports, and offers a free start.
