MillionVerifier vs ZeroBounce
These two sit at opposite ends of this market and neither is pretending otherwise. MillionVerifier sells verification as a commodity and prices it that way, at $449 for a million addresses. ZeroBounce sells a deliverability department where verification is one tab, and charges $39 before you check a single address.
| MillionVerifier | ZeroBounce | |
|---|---|---|
| Entry | 100 free credits, no card | $39 for a 2,000-credit minimum |
| At a million addresses | $449 | Subscription only |
| Credit expiry | Never, stated twice on their page | Roll over while the subscription runs |
| Accuracy claim | 99%+ | 99.6% |
| Unresolvable results | Billed, then fully refunded | No published policy we could read |
| Product scope | Verification, priced as a commodity | Verification plus a deliverability suite |

Where each one is stronger
What each vendor does that the other does not, stated as capability rather than advice.
MillionVerifier strengths
- MillionVerifier prices a bulk clean as the whole job. $449 for a million verifications is near the floor of this market, credits never expire on a true pay-as-you-go model, and 100 free credits get you in without a card. Their risky-email refund is the real differentiator: a full refund on any address they could not verify with certainty, which puts the cost of ambiguity on them rather than you. Worth knowing that the full package ladder sits behind a control on their homepage rather than a pricing page.
ZeroBounce strengths
- ZeroBounce answers several requirements from one subscription. Inbox placement testing, blacklist monitoring and DMARC tooling are separate products that would otherwise need separate vendors, and their activity data suggests recent engagement in a way no protocol check can. Their pricing is public: $39 buys a 2,000-credit minimum, with the suite priced into the floor whether you use it or not.
What separates MillionVerifier from ZeroBounce
The refund mechanic is the most interesting thing either vendor does with unresolvable addresses, and it deserves picking apart. MillionVerifier bills for them and then refunds anything it could not verify with certainty. ZeroBounce publishes no policy at all that we could find. A refund is plainly better than silence, and it still means the vendor decides which rows qualify and when the money comes back. Never charging removes that decision, and a handful of vendors including us take that route.
Credit terms split them three ways rather than two. MillionVerifier's never expire, stated twice on their own page. ZeroBounce keeps credits alive while the subscription is active, which is neither expiry nor permanence: stop paying and the balance stops mattering. For a team that cleans a list twice a year, those two models are worth very different amounts.
The products are not really the same shape, which any price comparison obscures. ZeroBounce sells a suite and charges a floor that reflects it, so $39 buys 2,000 credits and access to blacklist monitoring, inbox placement testing and DMARC tooling. MillionVerifier sells the commodity check and competes on the rate. Deciding between them is mostly deciding whether you want a deliverability department, and that question is answerable before either price is read.
What neither MillionVerifier nor ZeroBounce can do
Vendor accuracy percentages in this category count how often a returned verdict was right, calculated after the catch-alls and the servers that refuse to answer have left the denominator. Hunter tested the field across 40,000 verifications and measured 63% to 70%. Both kinds of figure are real and they are not measuring the same thing.
Questions about MillionVerifier and ZeroBounce
Why do some MillionVerifier tiers not appear here?
Their /pricing path returns a 404 and pricing lives on the homepage instead. Two packages were readable there, $89 for fifty thousand and $449 for a million. The rest sit behind a control that did not open for us, and we do not interpolate competitor prices.
Are never-expiring credits a real advantage over ZeroBounce?
A different one rather than a clear one. ZeroBounce credits roll over while you keep paying, so they do not expire so much as depend on you. MillionVerifier's promise survives a gap in spending, which is what matters to a team that cleans a list twice a year.
How far apart are they on price?
Far enough that it is not really a contest for bulk work. MillionVerifier publishes $449 for a million addresses. ZeroBounce's entry is $39 for a 2,000-credit minimum on a subscription, with the suite priced into the floor. They are selling different things at different scales.
What does the risky-email refund actually cover?
A full refund on any address they could not verify with certainty, in their own words, and they claim to be alone in offering it. Several vendors simply never charge for those addresses instead, which reaches the same number without the round trip.

A third option, and we built it
We sell a verifier too, and this page did not rank us because the question was about MillionVerifier and ZeroBounce. 100 free checks a month, no card, and the addresses nobody can resolve come back labeled rather than guessed.
