ZapBounce vs CaptainVerify
CaptainVerify runs on servers in France with ISO 27001 and SOC 2 behind them, recredits unknowns as a stated policy, and publishes no accuracy percentage. On unknowns ZapBounce goes one step further and never bills them at all. The rest of the comparison is the rate, and ZapBounce's is lower at every tier.

How CaptainVerify prices it
A pay-as-you-go ladder excluding tax: $8 for a thousand, $71 for ten thousand, $236 for a hundred thousand, $767 for a million. One oddity worth knowing, since we checked it twice: their ten-thousand tier works out marginally dearer per check than their five-thousand tier. Subscriptions take about 10% off the same ladder.
Why teams pick ZapBounce over CaptainVerify

The short version
- Lower at every tier: $5 against $8 for 1,000, $25 against $71 for 10,000, and $139 against $236 for 100,000.
- Credits never expire, stated on our pricing page. CaptainVerify's validity window is not stated on their public pages.
- 100 free credits every month, not only on opening an account.
- Unknowns are never billed in the first place, rather than recredited after the fact.
- Coverage reported on every list, so the share with a definite verdict is a number you can hold a vendor to.
Moving off CaptainVerify
Price at volume, usually. At a hundred thousand addresses they are $236 against ZapBounce's $139, and at ten thousand the gap is $71 against $25.
Easy technically: export, upload the same file to ZapBounce, and compare the unresolved share row for row. If you also run their HLR phone lookup, keep it on its own ladder; only the email side moves.
The hard addresses, and how they come back
Questions people ask about CaptainVerify
Is recrediting unknowns the same as never billing them?
Nearly. A recredit is a correction you have to notice and a non-charge is an invoice that never arrives. Both are far better than the market default, which is paying full rate for an address nobody could resolve.
How does deletion work on ZapBounce?
You can delete a batch and every address in it through the API, and erase a single address across the whole account for a GDPR request. Both are part of the published API reference.
Their ten-thousand tier looks dearer per check than the five-thousand one. Is that a typo?
We checked it twice on their own page and read it from the underlying price attributes rather than the render. It is what they publish. Worth asking them about if you sit near that boundary.
Is ZapBounce cheaper than CaptainVerify?
At 100,000 addresses we list $139 and they list $236. Compare the per-address rate rather than the headline, and check what each side does with unknowns: ours are never billed.
Can I test both before deciding?
Yes, and you should. Run the same sample of a few thousand addresses through each and compare how many came back unresolved. That difference matters more than either accuracy claim.
At a hundred thousand addresses it is $139 against $236. Add credits that never expire and unknowns that are never billed, and that is the comparison.
