ZapBounce vs ZeroBounce
ZeroBounce sells a deliverability department. Verification is one tab beside blacklist monitoring, inbox placement testing and DMARC tooling, and the subscription prices all of it together. Most lists only ever need the verifier. For that job, the 99.6% headline and the $39 floor are both worth a harder look, and so is what happens to the addresses nobody can resolve.

How ZeroBounce prices it
Subscription-led, with a 2,000-credit minimum at the entry. The per-address rate improves with tier, but the floor stays high because the suite is priced in. You are paying for breadth whether or not you use it.
Why teams pick ZapBounce over ZeroBounce
What changes when your list runs through ZapBounce instead.
The short version
- No 2,000-credit floor. ZeroBounce starts at $39 for 2,000 credits. ZapBounce starts at $5 for 1,000, with no minimum.
- Verification priced as verification. You pay for the checks you run, not for a suite priced into every tier, so 100,000 addresses cost $139.
- Unknowns are never billed, and the rule is printed on our pricing page. ZeroBounce states no policy on those addresses either way.
- Credits never expire, subscription or not. ZeroBounce credits roll over only while the subscription stays active.
- Coverage comes with every list: the share with a definite verdict, so the unresolved rows are counted in plain sight.
Moving off ZeroBounce
Price at volume, almost always. ZeroBounce sits at the top of this market and the gap is not marginal: their per-address rate is roughly ten to fifteen times the challenger tier. People stay for the surrounding suite and leave when they realize they only ever used the verifier.
Export the list, upload the CSV, and every row comes back as valid, invalid, catch_all or unknown, with role, disposable and free_provider flags beside it. If you also run their placement or blacklist tools, keep those on their own plan and move only the verification spend. Audit which of their tabs you actually open, then price the verifier on its own.
The hard addresses, and how they come back
Questions people ask about ZeroBounce
We use ZeroBounce for blacklist monitoring too. Can we move only the verification?
Yes. Verification is a separate job with a separate bill. Keep whichever of their tools you rely on and send the list cleaning to ZapBounce, at $5 for 1,000 or $139 for 100,000. Price the two parts apart and you will see what the verifier alone has been costing you.
Is the 99.6% figure wrong?
Probably not wrong. It answers a narrower question than it looks like it answers. It describes the verdicts they returned, after the accept-all domains and the servers that refused to answer had already left the pool. Ask what share of a test list reached a definitive verdict, and the number starts meaning something.
Why is their entry price $39 when yours is $5?
Their floor is a 2,000-credit minimum with the suite priced into it. Ours is 1,000 credits at $5 because verification is the only thing we sell. Neither is a trick. They are different products wearing the same category name.
Is ZapBounce cheaper than ZeroBounce?
At 100,000 addresses we list $139 and they list Subscription only. 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.
Run a few thousand addresses through both and compare the unresolved share against the accuracy claim. ZapBounce returns every row with one of four results, the literal SMTP code the server gave, and the unresolved count up front.
