ZeroBounce is a leading email verification and deliverability platform trusted by more than 350,000 customers worldwide. It validates email lists in bulk, scores individual address quality, and monitors sender reputation — giving revenue teams the clean data they need to reach inboxes, not spam folders.
Product Overview
ZeroBounce goes beyond simple syntax checks. Its AI-driven email scoring assigns a quality score to every address, predicting whether an email is likely to engage. The platform also offers an email finder to locate prospects' email addresses, a blacklist monitor to flag sender reputation issues, and an inbox tester that previews how messages render across 90+ email clients. A real-time validation API lets teams verify addresses at the point of capture — on sign-up forms, landing pages, or inside CRM workflows.
