Bouncer is a modern email verification and deliverability platform that helps B2B marketing and sales teams validate email lists, remove invalid addresses, and protect sender reputation before sending campaigns. Its API-first architecture makes it the preferred choice for developers and RevOps teams that want to integrate real-time email validation directly into their lead capture and enrichment workflows.
Product Overview
Bouncer's verification engine checks emails against multiple validation layers: syntax checking, domain MX record verification, disposable email detection, role-based address flagging (info@, admin@), spam trap identification, and real-time SMTP verification — all without actually sending an email. Its Toxicity Check feature goes beyond standard validation to identify addresses associated with known complaint generators and high-risk domains that would damage sender reputation even if technically valid. Bouncer's API allows real-time verification at the point of form submission — preventing invalid emails from entering the CRM before they cause deliverability damage. For bulk list hygiene, the batch upload interface processes millions of addresses and returns detailed per-address results with disposition codes.
