DeBounce vs ZeroBounce: Price at Volume, Expiry and Free Credits
DeBounce is cheaper than ZeroBounce at every size we compared, on both one-off packs ($25 against $129 for 10,000) and monthly plans ($124.20 against $449 for 100,000). ZeroBounce is the pick if you want its wider deliverability suite; DeBounce if price per address is what matters.
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
| DeBounce | ZeroBounce | |
|---|---|---|
| Free credits | 100 free credits (their page, fetched 9 Nov 2026) | 100 free monthly validations (Freemium plan, refilling every month; their page, fetched 9 Nov 2026) |
| Credit expiry | Credits never expire (their page, 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 (fetched 9 Nov 2026) |
| Catch-all handling | Their page lists a Catch-all Validator at 10 credits per validation; how uncertain results are billed is not stated (fetched 9 Nov 2026) | Not described on the pricing page; it says it never charges for Unknown results and duplicate removals (fetched 9 Nov 2026) |
Where a cell says it was fetched on 9 Nov 2026, we read it from the vendor's own page that day; "not checked today" means the page could not be fetched; 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
DeBounce is better for you if you verify up to about 10,000 addresses a month or clean a small list once. The catch: every option is metered by the credit, so every pass over the list is billed again.
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: DeBounce's smallest option is $13.80 a month for 5,000 on the entry subscription 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, DeBounce was $750 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 DeBounce's $23 (10,000) and ZeroBounce's $99 (10,000). That is where a flat plan pays off.
- DeBounce's $23 monthly plan for 10,000 is below Pro's $39. If 10,000 a month or less is your steady volume, DeBounce is the cheaper choice; Pro wins once you pass roughly 10,000 and want one flat price up to 100,000 at full speed.
