Is ZapBounce more accurate than CaptainVerify?

Neither of us can answer that from published figures. CaptainVerify states None published, and vendor accuracy claims in this market are calculated after unknown and catch-all addresses leave the denominator. We publish coverage next to accuracy so the denominator is visible, and our own measured benchmark is not published yet.

When is CaptainVerify the better choice?

Servers in France with ISO 27001 and SOC 2 certification. That combination satisfies a European data-residency clause, and most of this category, ours included, cannot offer it.

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. Three of those four are positions we argue for on every page of this site, which makes the honest version of this comparison quite short: they are more expensive at volume, and that is the argument.

	ZapBounce	CaptainVerify
Accuracy figure published	Coverage and accuracy together, once measured	None published
1,000 addresses	$5	$8 excluding tax
10,000 addresses	$25	$71
100,000 addresses	$139	$236
Free tier	100 a month, no card	100 credits on opening an account
Credit expiry	Never	Not published where we could read it
Billed for unknowns	No	No

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.

Where CaptainVerify is the better choice

Stated plainly, because a comparison page that never concedes anything is not worth reading.

Servers in France with ISO 27001 and SOC 2 certification. That combination satisfies a European data-residency clause, and most of this category, ours included, cannot offer it.
Unknowns are recredited, stated as a named feature on their pricing page rather than buried in terms.
They publish no accuracy percentage, which in this category is the defensible position.
HLR mobile-number verification on a separate ladder, which nobody else on this site offers at all.

Where we differ

What ZapBounce does differently

At a hundred thousand addresses they list $236 and we list $139.
We publish a credit expiry policy. Theirs was not stated where we could read it.
Our free tier is 100 credits every month. Theirs is 100 on opening an account.

Moving off CaptainVerify

Price at volume, usually. At a hundred thousand addresses they are $236 against our $139, and the gap widens against the cheapest end of this market. Data residency is the thing that holds their accounts in place.

Easy technically and a contract question first. French hosting and the certifications are often written into an agreement, and we are an uncertified vendor hosted outside France. That makes it a compliance decision rather than a tooling one.

What CaptainVerify cannot do either

The limits neither we nor CaptainVerify can price away

Recrediting unknowns removes the incentive to guess and it does not make a hard address resolvable. An accept-all domain accepts every recipient by design, and a refunded non-answer is still a non-answer sitting in your file.

Their certifications and their French hosting describe where data lives and how the business is run. Those are real and we hold neither. They do not change what Yahoo and AOL return, which is a success code for every recipient sent deliberately to stop harvesting.

Gmail and Microsoft 365 throttle or refuse probes from cloud ranges for both of us regardless of where the servers sit. Data sovereignty is a legal property, not a protocol one.

Pristine spam traps stay undetectable for both products. They are dearer than us at volume and better certified than us in every respect, and we would rather print both rows than one.

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.

We need EU data residency. Does that end it?

Yes, and we will say so on our own comparison page. Servers in France with ISO 27001 and SOC 2 is a specific answer to a specific requirement, and we do not have one.

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.

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.

CaptainVerify answers a French data-residency clause and we cannot. The one row we hold is $139 against $236 at a hundred thousand.

Run the same sample through us and CaptainVerify

100 free checks a month, no card, and the unknowns come back labeled.
