ZapBounce vs DeBounce
DeBounce posts the lowest headline rate in this category, from $0.00045 a check, and then prices the hard work separately. Catch-all validation bills ten credits an address and enrichment bills twenty. Whether that is cheap depends on a number most people have never counted: how much of their list sits on accept-all domains.

How DeBounce prices it
Lowest headline price in the category, with the difficulty billed separately. Ours is one rate per tier whatever the domain turns out to be, which is worse if your list is all Gmail and better if it is real B2B.
Where DeBounce is the better choice
Stated plainly, because a comparison page that never concedes anything is not worth reading.
- The lowest headline per-check price in the category.
- A verified Klaviyo partnership and wide ESP integration coverage.
- Charging separately for catch-all resolution is at least explicit about it being harder work.
Where we differ
What ZapBounce does differently
- Their headline rate excludes the extra credits catch-all validation costs. Ours is one rate.
- We do not bill unknowns at all.
What you give up leaving DeBounce

Moving off DeBounce
The à-la-carte credits. A headline rate of $0.00045 a check is genuinely low, and then catch-all validation bills ten credits and enrichment twenty, so a B2B list where a quarter of addresses are catch-all costs several times the advertised rate.
Easy technically. The work is recalculating what you actually spend, because their invoice and their pricing page describe different things once catch-all work is in the mix.
What DeBounce cannot do either
Questions people ask about DeBounce
How do we work out what DeBounce actually costs us?
Take your last invoice, divide by the addresses processed, and compare that with the headline rate. The gap is the catch-all and enrichment credits. On a real B2B list that gap is often larger than the base charge.
Is à-la-carte pricing dishonest?
No, and we would rather argue against it on the merits. Harder work costing more is defensible. The problem is that the advertised number describes the easiest possible list, so nobody can price a decision from it.
What does your single rate cost on an easy list?
More than theirs. If your list is nearly all Gmail and Outlook, DeBounce's headline rate is genuinely cheaper and we are not going to argue otherwise. Our flat rate wins on the lists where their extras stack up.
Is ZapBounce cheaper than DeBounce?
At 100,000 addresses we list $139 and they list Tiered. 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.
Divide your last DeBounce invoice by the addresses it covered. Compare that figure with our tiers, not the headline rate.
