Why people look elsewhere
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.
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.
What ZapBounce changes for a DeBounce user
The differences that show up on the first invoice and the first results file.
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.
Before you move off DeBounce
Run the same sample through two vendors and the interesting number is not how many came back valid.
Reconcile the invoice against the headline
Divide your last DeBounce invoice by the addresses it covered. The difference from $0.00045 is the catch-all credits, and it's the number to set beside ZapBounce's ladder.
List the connections you rely on
Note which of DeBounce's integrations actually trigger checks. Plan each one as an API call, a file step or a Zap before the switch.
Count your accept-all share
Per-credit catch-all pricing rewards a consumer list and costs more on a B2B one. That one share tells you which side of the trade you've been on.
Pick a retention window
DeBounce deletes after 7 days. ZapBounce lets you delete a job at any time with DELETE /v1/jobs/{id}.
What switching actually involves
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.

Questions about moving off DeBounce
Why is my DeBounce bill higher than the headline rate?
Catch-all validation. It costs 10 credits an address on top of the base check (DeBounce's pricing page, read 24 September 2026). A B2B list with many accept-all domains can cost far more than the advertised rate.
Does ZapBounce charge extra for catch-all addresses?
No. A catch_all result costs one credit, the same as valid or invalid, and an unknown costs nothing. The price of a file is its size at the tier rate, less unknowns and duplicates.
How long does DeBounce keep an upload?
DeBounce deletes files 7 days after upload or validation. ZapBounce lets you delete a job as soon as you have downloaded it, with DELETE /v1/jobs/{id}.
Why do people leave 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.
How hard is it to switch verifiers?
For bulk cleaning, no harder than uploading the file somewhere else. For real-time checks on a signup form it is an API swap, which is an afternoon.
