Zerobounce

ZeroBounce is an email validation and deliverability platform designed to help organizations maintain clean, accurate, and high-performing email lists. The tool analyzes email addresses in bulk or via real-time API to identify invalid, abuse, spam trap, disposable, catch-all, and role-based addresses before they damage sender reputation. It performs syntax checks, domain and MX record validation, and mailbox existence verification to reduce bounces and improve inbox placement.

Beyond validation, ZeroBounce enriches email data by adding missing information such as gender, location, and other metadata when available, supporting better segmentation and personalization. Its email deliverability toolkit includes inbox placement testing, blacklist monitoring, and sender score insights, helping users diagnose and resolve issues that affect campaign performance.
