Why teams pick ZapBounce over EmailVerify.io
What changes when your list runs through ZapBounce instead.
The short version
- At a million addresses, $949 against their $1,015.
- Every ZapBounce credit is permanent. Their subscription credits roll for two months, and only pay-as-you-go credits never expire.
- Coverage beside every result. Their 99%+ headline carries no denominator.
- No charge for unknowns or duplicate rows, a rule stated on our pricing page. EmailVerify.io does not state a policy on unknowns.
- A POST-only API, so addresses never appear in a URL, a browser history or an access log on the way to be checked.
Moving off EmailVerify.io
The denominator question. Their 99%+ headline carries no coverage figure beside it, and buyers who want the unresolved share as a number look for a vendor that reports it on every list.
Straightforward. If an agent workflow calls their MCP endpoint, list the calls it makes. ZapBounce's REST API covers single checks, jobs of up to 50,000 addresses and polling for results, so each call maps to a plain HTTP request.
The hard addresses, and how they come back
Questions people ask about EmailVerify.io
What decides it if the prices are close?
Whether you can see the share of your list that never reached a verdict, and whether you paid for those addresses. ZapBounce reports the first as coverage and never bills the second. At a million addresses it is also $66 cheaper.
What is missing from 99%+?
Its denominator. Ask what share of the test list produced a definitive verdict. The plus sign at the end is doing less work than it appears to, because the figure was computed after the hard addresses were excluded.
How does ZapBounce fit into an automated workflow?
Through a plain REST API: POST /v1/verify for one address, jobs of up to 50,000 addresses through POST /v1/jobs, and polling GET /v1/jobs/{id} until a job completes. Requests authenticate with an X-API-Key header.
Is ZapBounce cheaper than EmailVerify.io?
At 100,000 addresses we list $139 and they list $130, and 1,000,000 for $1,015. 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.
Ask them what share of your list reached a verdict, and decide on that answer. ZapBounce puts that share on every list it returns.
