Clearout vs ZeroBounce: Price at Volume, Annual Billing and Credit Rollover

Clearout is cheaper than ZeroBounce at every size we compared, on both one-off packs ($65 against $129 for 10,000) and monthly plans ($360 against $449 for 100,000). ZeroBounce is the pick if you want its wider deliverability tools; Clearout if you want the lower price, rolling credits and a prospecting database alongside.

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.

Credits, expiry and free allowances

	Clearout	ZeroBounce
Free credits	100 free credits (their page, 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 and carry forward; unused subscription credits roll over (their FAQ, 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 page mentions resolving more catch-all and SEG-protected emails into Valid or Invalid with Deep Verify, without detail (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

Clearout is better for you if you want their prospecting database and integrations bundled with verification, or the lowest published monthly price at 1,000,000 a month in this group ($1,260 against $2,499 at ZeroBounce). The catch: the monthly-billed price is far above the annual one, so the low headline needs a year's commitment.

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: Clearout's smallest option is monthly from $23 for 3,000 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, Clearout was $1,400 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 Clearout's $58 (10,000) and ZeroBounce's $99 (10,000). That is where a flat plan pays off.
