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
Pay-as-you-go only, with tier prices in a calculator and credits that never expire. Catch-all validation is a separate product at 10 credits an address. ZapBounce bills a catch_all row at the same single credit as any other, so the quote before a run is the bill after it: $25 for 10,000 and $139 for 100,000.
Why teams pick ZapBounce over DeBounce
What changes when your list runs through ZapBounce instead.
The short version
- One rate per tier, whatever the domain. A catch-all result costs the same single credit as any other, with no ten-credit surcharge.
- Unknowns are never billed. DeBounce's pages do not state a policy on unknowns.
- The invoice matches the pricing page: $25 for 10,000 and $139 for 100,000, whatever share of the file sits on accept-all domains.
- Coverage reported on every list, so you see how many rows sat on accept-all domains before you plan a send.
- 100 free credits that renew every month, enough to test a catch-all-heavy sample before a full run.
Moving off DeBounce
The gap between the headline rate and the invoice. DeBounce's checks start at $0.00045 each, and catch-all validation costs 10 credits an address (read 24 September 2026). On a B2B file where many rows sit on accept-all domains, that second line sets the bill.
List the connections first. DeBounce plugs into HubSpot, Mailchimp, Klaviyo, Mailjet, SparkPost, Google Sheets, WordPress, WooCommerce and Zapier. ZapBounce covers those jobs through its API and CSV upload, so rebuild each flow you actually run before the switch.
The hard addresses, and how they come back
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 a single rate buy on a B2B list?
Predictability. A file where a quarter of the addresses sit on accept-all domains costs the same per address as one full of Gmail. The quote before the run is the bill after it. On DeBounce the same file adds ten credits for every catch-all validation.
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: 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.
Divide your last DeBounce invoice by the addresses it covered. Compare that figure with our tiers, not the headline rate.
