Why people look elsewhere
The rate at volume, almost always. Bouncer's ladder is easy to read, and it runs from $8 for 1,000 to $2,000 for a million. You'd pay $5 and $949 for the same work at ZapBounce, under the same no-charge rule for duplicates and unknowns.
Bouncer sells credits pay-as-you-go: $8 for 1,000, $60 for 10,000, $400 for 100,000 and $2,000 for a million (its pricing page, read 24 September 2026). ZapBounce's ladder has the same shape at $5, $25, $139 and $949. It also offers a monthly plan that costs 15% less than the same credits bought pay-as-you-go.
What ZapBounce changes for a Bouncer user
The differences that show up on the first invoice and the first results file.
The short version
- Lower at every published tier: $5 against $8 for 1,000, $25 against $60 for 10,000, and $139 against $400 for 100,000.
- At a million addresses, $949 against Bouncer's $2,000, with the same no-expiry credits.
- 100 free credits every month, recurring, with no card, so a small weekly batch may never need a purchase.
- Coverage reported on every list: the share with a definite verdict is a number you read, not one you work out.
- Our own SMTP check on port 25, closed before DATA, so no message is ever sent to the addresses you verify.
Before you move off Bouncer
Run the same sample through two vendors and the interesting number is not how many came back valid.
Price your usual file on both ladders
Take the size of the list you clean most often. At 10,000 addresses Bouncer lists $60 and ZapBounce lists $25. At 100,000 it's $400 against $139.
Rewrite rules built on the toxicity score
ZapBounce returns valid, invalid, catch_all or unknown on every row, plus role, disposable and free_provider flags and the literal SMTP code. Map each field your workflow reads before the first upload.
Read both retention clauses
Bouncer's GDPR page says 60 days and its privacy policy says up to 365. Ask which one covers your account, then plan to delete finished ZapBounce jobs with DELETE /v1/jobs/{id}.
Keep the billing rules you're used to
No charge for duplicates or unknowns, and credits that never expire. ZapBounce prints all three rules on its pricing page, so nothing moves backwards.
What switching actually involves
Your budget rules don't change. Both vendors leave duplicates and unknowns off the bill and neither expires credits. A rule built on Bouncer's toxicity score gets rewritten against ZapBounce's four results and its role, disposable and free_provider flags. Upload the same CSV to both and compare the unknown rows before you move a larger file.

Questions about moving off Bouncer
Is ZapBounce cheaper than Bouncer?
Yes, at every tier Bouncer publishes. For 100,000 addresses Bouncer lists $400 and ZapBounce lists $139, and at a million it's $2,000 against $949 (Bouncer's pricing page, read 24 September 2026). The rules on duplicates, unknowns and expiry stay the same.
How long does Bouncer keep an uploaded list?
Bouncer's GDPR page says 60 days, and its privacy policy says up to 365 days (both read 24 September 2026). You can delete a ZapBounce job at once with DELETE /v1/jobs/{id}.
Can we test ZapBounce before we move?
Yes. A new account gets 100 free credits with no card, and 100 more arrive every month. That's enough to run a sample Bouncer already checked and compare the results row by row.
Why do people leave Bouncer?
The rate at volume, almost always. Bouncer's ladder is easy to read, and it runs from $8 for 1,000 to $2,000 for a million. You'd pay $5 and $949 for the same work at ZapBounce, under the same no-charge rule for duplicates and unknowns.
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.
