BounceZero runs every email through a 5-stage pipeline: syntax, MX/DNS, real-time SMTP probing, provider-specific checks (Gmail, Outlook, Yahoo, ProtonMail + 20 more), and an AI scoring engine that returns a confidence score from 0–100. Results: verified / likely_valid / risky / catch-all / invalid — in under 2 seconds. What's different: • AI scoring catches what rule-based tools miss • 100 free credits every month, no card required • Credits never expire — no subscription pressure

Hey hunters! 👋
I built BounceZero after watching our email campaigns tank because of
bounces — even after "cleaning" lists with the usual tools.
The problem: most verifiers just check if an MX record exists. BounceZero
actually probes the mailbox in real time, runs provider-specific logic for
20+ email hosts, and layers an ML model on top to score edge cases like
catch-alls and hosted domains.
100 free credits every month, no card needed. Would love your feedback on
what's missing or what you'd want to see next.
