StopBouncing Reviews & Product Details

StopBouncing is a pay-as-you-go email verification service that helps businesses reduce bounce rates and protect sender reputation. It runs every address through a multi-step verification pipeline — syntax checks, MX record lookup, SMTP handshake, catch-all detection, disposable email detection, and role-based address filtering — and returns a 0–100 confidence score with a clear valid/invalid/unverifiable result. Key features: bulk CSV upload with downloadable results, real-time REST API for in-app verification, and a free single-address checker. Credits never expire and no subscription is required. Pricing starts at €18 per 10,000 verifications with 100 free credits to get started. Hosted in the EU and fully GDPR-compliant, making it the right choice for European businesses and any company with EU data residency requirements. Supports crypto payments (BTC, ETH, USDT, and more) in addition to credit cards.
