Built around the million-row list
MillionVerifier's clearest number is $449 for a million verifications. If you clean one huge file at a time, that price is the reason to look. The 50,000 pack is $89, and credits never expire, so a big pack can sit until the next import.
The smaller packs sit behind a See all packages button on the homepage, and the /pricing path returns a 404. Our MillionVerifier pricing page sets out every tier we could read. ZapBounce prints its whole ladder on one pricing page, from $5 for 1,000 to $949 for a million.
The 99%+ claim and how to read it
MillionVerifier says 99%+ accuracy on its homepage. Most vendors in this market print a number between 98% and 99.7%. Few of them say what the denominator was, or how many addresses came back unresolved.
That second number is the one to ask for. A tool that leaves a large share of a B2B list unresolved can still be 99% right on the rows it did call. ZapBounce reports coverage on every file, the share of rows with a definite verdict, so you can see both halves. Read what accuracy is actually achievable before you trust any single figure.
Catch-all rows and what they cost
MillionVerifier sells a catch-all pass that charges one credit only when a catch-all address reaches a definite result. Addresses it can't resolve aren't charged at all. That's a fair billing rule, and the size of your invoice follows how many rows come back clean.
ZapBounce takes a different route. One probe to a random address at the same domain shows whether it accepts everything. If it does, the row comes back catch_all, costs one credit, and nothing further is guessed. You then decide how to warm that slice up. Our catch-all glossary entry explains why no verifier can see behind an accept-all server.
The guarantee, the terms and your data
MillionVerifier offers a money-back guarantee, but it's conditional. The terms list the conditions, including a hard-bounce ceiling and a short claim window. Read them before you count on a refund for a whole campaign.
Its terms permit lists from a data provider or broker, as long as they were lawfully acquired. Its privacy policy says customer lists aren't used for its own marketing. ZapBounce never sells uploaded addresses or adds them to a shared database, and each batch can be deleted at once through the API.
Matching the ladder to how you clean
Price follows the shape of your work. A few very large files a year put the million pack in focus. Steady batches of a few thousand put the small tiers and the free allowance in focus instead.
Price both shapes before you pick. ZapBounce gives 100 free credits every month with no card and never bills an unknown or a duplicate. The product side by side is on ZapBounce vs MillionVerifier, MillionVerifier vs ZeroBounce covers another pairing, and the comparisons hub lists the rest.
The scorecard on MillionVerifier
Both columns are required here. A page that only fills one is an advertisement wearing a review's clothes.

- $449 for a million verifications, printed on the homepage.
- Credits never expire: "No contracts. No expiry. No gotchas."
- Unresolved addresses are not charged.

Where MillionVerifier falls short

- The 99%+ claim is printed without a published test set or unresolved share.
- The money-back guarantee applies only on conditions set out in its terms.
- Pay-as-you-go only, and the free allowance is a one-time signup grant.
