Bouncer

Bouncer is an email verification and deliverability platform designed to help you maintain a clean subscriber list and stay out of the spam folder. You can upload large CSV files for batch cleaning or use the real-time API to verify email addresses directly at the point of entry on your signup forms. The system identifies undeliverable, risky, and disposable email addresses so you only send to real people.

Beyond simple verification, you get a deliverability kit to test your inbox placement and monitor your sender reputation across different providers. It is built for businesses of all sizes, from solo marketers to large enterprises, offering a secure infrastructure that complies with GDPR. You can start with 100 free credits to test the accuracy before committing to a pay-as-you-go or monthly subscription model.
