Bouncer

About

Bouncer is a tool for a small shop's email marketing / email verification work — a job the shop already does. Bouncer is a GDPR-compliant, EU-hosted email verification platform that helps businesses improve data quality, increase email marketing ROI, and protect sender reputation. Its core services include list verification (batch cleaning), a real-time verification API, Bouncer Shield (form-level protection against invalid or fraudulent signups), Toxicity Check (identifies spam traps and breached addresses on a 0–5 scale), Email Engagement Insights (last open, click, and reply dates), and a Deliverability Kit for inbox placement testing and blocklist monitoring. Over 4 billion email addresses verified with less than 2% unknown results.
