Why teams switch from MillionVerifier to BounceZero

Equal speed, deeper intelligence, credits that do not expire

5-stage pipeline vs single SMTP scan

MillionVerifier is fast but depth-limited: it performs SMTP handshake and disposable/syntax checks. BounceZero runs a 5-stage pipeline: MX validation, domain reputation, SMTP deep probe, 3-probe catch-all test, and Bayesian + ML scoring. This catches addresses that pass MillionVerifier's probe but will still bounce - particularly on catch-all domains and ISP-hosted inboxes.

Plain-English explanations per result

MillionVerifier returns a verdict: Valid, Invalid, Catch-all, Disposable. BounceZero returns the verdict plus a confidence score (0-100) and a plain-English explanation. For catch-all and risky addresses, you get specific guidance: which DNSBL flagged the domain, what the SMTP probe returned, and whether social signals confirm inbox activity.

A free tier that renews every month

Both services sell never-expiring credits - no advantage either way there. BounceZero adds 100 free credits every month (no card required), so you can spot-check accuracy on your specific list types before purchasing, and keep spot-checking new sources monthly without spending a credit you paid for.
