Overview

BounceBan is an email verification platform designed to improve deliverability by validating complex email addresses, including catch-all and those protected by Secure Email Gateways (SEG). The tool utilizes proprietary algorithms to determine the deliverability of emails that standard verification tools often struggle with, achieving over 97% accuracy for catch-all emails without sending messages. It serves sales and marketing professionals by providing free unlimited single email verification, credit-based bulk list processing, API access for automated workflows, and a Sync subscription for daily CRM verification. The service is GDPR and CCPA compliant with unused credits rolling over indefinitely.
