ZapBounce vs EmailHippo
EmailHippo is the only vendor on this site that holds ISO 27001 and ISO 9001 and a Queen's Award, and the only one selling fraud intelligence alongside verification. Those two facts make this a lopsided comparison in both directions: they win procurement outright, and we sell the commodity check they use as an entry point.

How EmailHippo prices it
Four ladders rather than one. Bulk verification starts at $9.88 a month, the real-time API at the same floor, the intelligence product at $12.26 and fraud prevention at $14.63. Above those floors everything sits behind a calculator, and volumes past 2.5 million a month go to sales. Pay-as-you-go carries a stated minimum transaction fee and no charge for duplicates.
Where EmailHippo is the better choice
Stated plainly, because a comparison page that never concedes anything is not worth reading.
- ISO 27001 and ISO 9001 together, plus a Queen's Award. That is the strongest certification stack of any vendor on this site and it clears procurement gates that stop most challengers dead.
- Their fraud-prevention and intelligence products answer a question a verifier cannot: not does this mailbox exist, but is this signup dangerous. Dark-web checks, risk scoring, IP and location analysis, Tor detection.
- No charges for duplicate emails, stated on their own pay-as-you-go terms.
- 250 requests a second published, which is an order of magnitude above what several developer-first competitors allow.
Where we differ
What ZapBounce does differently
- Our full price ladder is published. Theirs sits behind a calculator above the entry floor.
- We sell one product. They sell four, and the entry price is for the narrowest one.
- We never bill for unknowns, stated as a rule rather than a duplicate-specific concession.

Moving off EmailHippo
Scope and price shape. A team that wanted a list cleaned finds it has bought the entry tier of a fraud-intelligence platform, and the volume pricing above that tier requires working a calculator rather than reading a table.
Depends entirely which of the four products you use. Replacing the bulk verification is ordinary. Replacing the fraud scoring, dark-web checks or domain intelligence is not, because nothing in this category reproduces them and the replacement is a different vendor in a different market.
What EmailHippo cannot do either
Questions people ask about EmailHippo
We need ISO 27001. Does that end the comparison?
For a security review that requires it, yes, and we will not argue otherwise. EmailHippo holds ISO 27001 and ISO 9001. We hold neither, and most of the challengers in this category do not either.
What does the fraud product do that verification does not?
It asks whether a signup is dangerous rather than whether a mailbox exists. Risk scoring, domain reputation, IP and location analysis, Tor detection, dark-web exposure. A verifier answers a narrower question and nothing here substitutes for the wider one.
Why are their volume prices missing from this page?
Because they sit behind a calculator above the entry floor. We can publish the floors, which are $9.88 a month for bulk and real-time, $12.26 for intelligence and $14.63 for fraud prevention. A price we did not read at your volume does not go on this page.
Is ZapBounce cheaper than EmailHippo?
At 100,000 addresses we list $139 and they list Behind their pricing calculator. Compare the per-address rate rather than the headline, and check what each side does with unknowns.
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.
EmailHippo carries ISO 27001 and ISO 9001 through a security questionnaire. Certifications are the one row on this page we cannot answer at all.
