BounceZero's answer
BounceZero runs a true 5-stage verification pipeline โ syntax, DNS/MX, live SMTP handshake, catch-all detection, and ML scoring โ on every address. Most competitors stop at SMTP. We go further with a 3-probe catch-all test, XGBoost risk scoring for providers that block SMTP probes, and per-provider intelligence built from 200+ email provider profiles including every major ISP in Europe, the US, and Latin America.
BounceZero's answer
Python (FastAPI) for the verification engine and API, PostgreSQL for data storage, XGBoost and Bayesian models for ML scoring, SMTP probing across dedicated IP pools for deliverability testing, and a PHP frontend. Hosted on OVH infrastructure with BYOIP egress for clean sending reputation.
BounceZero's answer
Three reasons: accuracy, transparency, and price. BounceZero returns a confidence score and plain-English explanation with every result โ not just a pass/fail verdict. It costs $3 per 1,000 verifications with no subscription required and 100 free credits every month. And the API returns results in under 3 seconds with no rate limits on paid plans.
BounceZero's answer
Email marketers, growth teams, and developers who send campaigns or build signup flows and need to keep bounce rates below 2%. Also agencies cleaning client lists before migrations and SaaS companies validating email at the point of collection via API.
BounceZero's answer
BounceZero was built after seeing too many email campaigns destroyed by high bounce rates that could have been prevented. Existing tools were either expensive subscription products or black-box APIs that gave a verdict with no explanation. We built BounceZero to be affordable, transparent, and accurate โ starting with 100 free credits so anyone can test it without a credit card.
