Why people look elsewhere
Most people want a price they can set beside other vendors in one sitting. NeverBounce sells two ways, pay-as-you-go credits and a subscription it calls Sync, so the rate you pay depends on which one your account sits on. ZapBounce prints one ladder for both jobs, from $5 for 1,000 to $949 for a million.
NeverBounce's current figures are on its own pricing page, split between pay-as-you-go credits and the Sync subscription. ZapBounce publishes one ladder: $25 for 10,000, $139 for 100,000 and $949 for a million, the same for a file upload or an API call. A monthly plan costs 15% less than the same credits bought pay-as-you-go, and unused credits roll over while it's active.
What ZapBounce changes for a NeverBounce user
The differences that show up on the first invoice and the first results file.
The short version
- Prices you can check. ZapBounce lists every tier on one page, from $5 for 1,000 to $949 for a million, with no minimum purchase.
- Coverage stated beside every result, so you see what share of the list reached a definite verdict instead of one headline percentage.
- Unknowns and duplicates are never billed, and the rule is printed on our pricing page. NeverBounce does not state a policy on its reachable pages.
- Credits never expire. NeverBounce's expiry terms are not stated on its reachable pages.
- One ladder, no second rate. A file upload and an API call spend the same credits at the same published price, so there is no metered rate to get stuck on.
Before you move off NeverBounce
Run the same sample through two vendors and the interesting number is not how many came back valid.
Map five results onto four
NeverBounce's disposable result becomes ZapBounce's disposable flag, which sits beside a valid or invalid result. Update any segment that filters on it before your first upload.
Price last quarter's volume on our ladder
Pull the verified count from your NeverBounce invoices and price it on ZapBounce's table: $25 for 10,000, $139 for 100,000, with unknowns and duplicates left off.
Get the unknown-billing rule in writing
NeverBounce's readable developer docs state no billing rule for unknown results. ZapBounce never bills an unknown or a duplicate, and says so on its pricing page.
Check how long your credits last
Kickbox and Hunter expire credits after twelve months. ZapBounce credits never expire, so a balance bought for one project waits for the next list.
What switching actually involves
NeverBounce returns five results: valid, invalid, disposable, catchall and unknown (its developer docs, read 24 September 2026). ZapBounce returns four, valid, invalid, catch_all and unknown, and moves disposable to a flag that sits beside the result with role and free_provider. Point any rule that reads their disposable result at our disposable flag, and every other rule carries straight across.
What stays true whichever verifier replaces NeverBounce
Questions about moving off NeverBounce
What does a NeverBounce unknown become on ZapBounce?
It stays unknown. NeverBounce's docs describe unknown as a server that could not be reached, and ZapBounce uses the same result for any server that won't give a final answer. The reason field tells you which case it was, such as timeout or greylisted, and an unknown is never billed.
Can we test ZapBounce on a list NeverBounce already checked?
Yes. A new account gets 100 free credits with no card, and 100 more arrive every month. Run a sample your NeverBounce account already checked, then compare the rows side by side, including the smtpCode ZapBounce returns for each one.
What changes in our code if a script calls NeverBounce today?
One call. ZapBounce verifies a single address with POST /v1/verify and takes a list through POST /v1/jobs, and you poll GET /v1/jobs/{id} to learn when the results are ready. No-code flows call the API from an HTTP request step.
Why do people leave NeverBounce?
Most people want a price they can set beside other vendors in one sitting. NeverBounce sells two ways, pay-as-you-go credits and a subscription it calls Sync, so the rate you pay depends on which one your account sits on. ZapBounce prints one ladder for both jobs, from $5 for 1,000 to $949 for a million.
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.
Run a sample your NeverBounce account already checked through ZapBounce's 100 free credits, then compare the unknown rows one by one.
