¹ MillionVerifier pricing verified 7 Aug 2026 against millionverifier.com/pricing: $89 per 50,000 credits, $449 per 1,000,000, no subscription, credits never expire. Rows marked "—" were not independently verified and are left unquoted rather than guessed. ² Accuracy figures are vendor claims, not independent benchmarks. BounceZero's figure is scoped to SMTP-verifiable addresses; catch-all and provider-blocked mailboxes are probabilistic. See product facts.
MillionVerifier is a volume play: cheap credits, a simple Valid/Invalid/Unknown-style verdict, no subscription, and credits that never expire. At 50K-plus it is genuinely the cheaper product per check, and for a flat go/no-go list clean that may be all you need.
BounceZero makes the opposite bet: one flat published price, and a deeper result model where each verdict is explained. Instead of a bare status you get 65+ verification and metadata fields, an explicit advanced catch-all classification, domain intelligence, and plain-English reasons for the risky middle of your list.
Neither structure is wrong. Six-figure volume with a core verdict only favours MillionVerifier; bursty work where you need to understand the borderline records favours BounceZero.
BounceZero returns 65+ evaluated and/or returned verification and metadata fields and labels borderline records Risky with the signals behind them. That is not a claim that 65 independent models run for every provider; it is a description of the result model your integration sees.
BounceZero costs a flat $3 per 1,000 whether you verify 2,000 or 2,000,000 addresses, with 100 free credits renewing every month and no card required. MillionVerifier is cheaper per check at volume, so run both at your exact volume before you move.

MillionVerifier figures verified 7 Aug 2026 (millionverifier.com/pricing). BounceZero figures: bouncezero.io/pricing.
No, at volume. MillionVerifier charges $89 per 50,000 credits ($1.78 per 1,000) and $449 per 1,000,000 ($0.45 per 1,000), no subscription, credits never expire (verified 7 Aug 2026). BounceZero is a flat $3 per 1,000. If price per check is the only factor at your volume, MillionVerifier is cheaper.
Both figures are vendor claims from different datasets, not a shared independent benchmark. BounceZero internal testing reports up to 99.8% on SMTP-verifiable addresses; catch-all and provider-blocked mailboxes remain probabilistic. Test both products on the same representative list and keep Risky and Unknown separate.
They overlap on bulk uploads and REST APIs, but differ in the result model: BounceZero evaluates and/or returns 65+ fields and explains each verdict, while MillionVerifier returns a core deliverability verdict with a smaller published field set. Compare the exact API fields your workflow requires rather than treating the products as identical.
Both flag catch-all behaviour. BounceZero returns an explicit advanced catch-all classification with supporting signals so borderline mailboxes are labelled Risky rather than a bare verdict. Verify how each vendor reports catch-all on your own list, because provider behaviour varies and neither approach is perfect.
Yes - if what you need is a flat, published price with no volume tiers, 100 free credits that renew monthly, credits that never expire, and a deeper per-record result model with plain-English explanations. The honest caveat: at 50K-plus volume MillionVerifier is cheaper per check, so if you only need a core verdict and volume is your constraint, compare both at your exact volume.
