BounceZero

BounceZero is an enterprise-grade email verification platform that identifies invalid, disposable, role-based, catch-all, and spam-trap addresses before they damage your sender reputation.

Unlike validators that rely on syntax checks alone, BounceZero uses a multi-stage pipeline combining live SMTP probing, DNS analysis, machine learning models, and ISP-level intelligence to return definitive verdicts — not ambiguous "unknown" results.

Key features: • Real-time single & bulk email verification • REST API with ready-made integrations (Zapier, Make, HubSpot, ActiveCampaign, Mailchimp, Klaviyo) • 65+ signals: SMTP, MX, SPF, DMARC, ML scoring, behavioral patterns • Disposable/temporary email detection (50,000+ domains) • Role address detection (info@, support@, noreply@, etc.) • Spam trap and honeypot identification • Catch-all domain handling with probabilistic scoring • Results in under 3 seconds for 98% of addresses • Built for scale — millions of verifications per day • Pay-as-you-go or subscription plans; 500 free credits to start
