MillionVerifier vs ZeroBounce: One-Off Packs Against a Subscription

MillionVerifier is much cheaper than ZeroBounce on every published size we compared ($149 against $649 for 100,000), and its credits never expire. ZeroBounce is the choice if you want its wider deliverability suite or a monthly subscription; MillionVerifier if the job is cleaning lists as cheaply as possible.

Neither is the best answer for everyone, and for steady monthly volume a flat plan from a third vendor can cost less than both. Prices below are what each vendor published on the dates shown.

Where a size was not a listed pack, the next pack up covers it. "No subscription listed" means we found no monthly plan on the page when we read it.

Credits, expiry and free allowances

	MillionVerifier	ZeroBounce
Free credits	100 free credits, no card needed (their site, fetched 9 Nov 2026)	100 free monthly validations on sign-up with a business domain (their page, fetched 9 Nov 2026)
Credit expiry	Credits never expire (their site, fetched 9 Nov 2026)	Credits never expire while you have an active ZeroBounce ONE subscription; without one, the page says expiration rules may apply depending on when the account was created or credits bought (fetched 9 Nov 2026)
Catch-all handling	Their site says "advanced catch-all verification at no extra cost" without explaining how it works (fetched 9 Nov 2026)	Not described on the pricing page

Where a cell says it was fetched on 9 Nov 2026, we read it from the vendor's own page that day; the rest comes from the dated pricing data above. We make no claim about accuracy for either vendor, and nobody can honestly rank verifiers on accuracy from a pricing page.

Who each is better for

MillionVerifier is better for you if you clean very large lists occasionally: 1,000,000 checks for $449 with credits that never expire is the lowest published one-off rate in this group. The catch: every pass is a fresh purchase, so a list you re-check monthly is bought again each time.

ZeroBounce is better for you if you need their wider deliverability suite (inbox placement testing, blacklist monitoring and email server testing alongside verification) or a free monthly allowance. The catch: credits are the unit, so the bill scales with list size and a re-check costs full price again.

A third option: SimpleVerifier

SimpleVerifier Pro is a flat $39 a month. The first 100,000 checks a month run at full speed; after that it slows down but never cuts you off. Results are split into valid, risky and invalid, and risky means risky: a catch-all or otherwise uncertain address is labelled as such rather than counted as good.

Honest limits:

• At very small volumes one-off packs cost less than $39: MillionVerifier's smallest option is $39 for 10,000 credits and ZeroBounce's is $39 for 2,000 pay-as-you-go. If that is all you need, buy that.
• If you clean one very large list once, a one-off pack can beat a month of Pro. At 1,000,000 checks one-off, MillionVerifier was $449 and ZeroBounce was $3,199, all at full speed; on Pro only the first 100,000 a month run at full speed.
• If you verify 10,000 or more every month, compare Pro's $39 with MillionVerifier's $39 one-off for 10,000 and ZeroBounce's $99 (10,000). That is where a flat plan pays off.
