ZapBounce vs Xverify
Xverify refuses to cache results. Every request is a fresh lookup, which they state on their own site as the reason for their accuracy, and it is also the reason they cost $400 at a hundred thousand where the price-led tier charges under a hundred. That trade is the whole comparison and it is a legitimate one.
| ZapBounce | Xverify | |
|---|---|---|
| Accuracy figure published | Coverage and accuracy together, once measured | 98%, in their words, across the major domains |
| 1,000 addresses | $5 | $10 |
| 10,000 addresses | $25 | $70 |
| 100,000 addresses | $139 | $400 |
| Free tier | 100 a month, no card | 100 verifications, one-time |
| Credit expiry | Never | Not stated anywhere we could find |
| Billed for unknowns | No | No |

How Xverify prices it
A flat ladder from $5 for five hundred to $2,500 for two and a half million, with $10 at a thousand, $70 at ten thousand and $400 at a hundred thousand. No minimum and no setup fee. The rate reflects a real decision: refusing to cache means every check costs them something, and the price says so.
Where Xverify is the better choice
Stated plainly, because a comparison page that never concedes anything is not worth reading.
- No caching, stated plainly on their own site. A cached verdict is how a cheap verifier keeps its rate low, and refusing to do it is an expensive, defensible choice most of this market will not make.
- A timeout past seven seconds is recorded as unknown and is not a billable transaction, written into their FAQ rather than implied.
- Email, phone and postal address verification from one US company with a published support line, which suits a buyer who wants one number to call.
- They understand the lead-generation buyer, where a fake form submission burns acquisition spend that a list clean can never recover.
Where we differ
What ZapBounce does differently
- At a hundred thousand addresses they list $400 and we list $139.
- We report coverage next to accuracy rather than a single 98% figure.
- Their site still shows a Privacy Shield badge, and that framework was invalidated in 2020.

Moving off Xverify
Price at volume, once the job turns out to be a list rather than a form. At a hundred thousand addresses they are $400, which is what a no-caching policy costs to run and roughly three times the price-led tier of this category.
The bulk half moves in an afternoon. The form half does not: real-time validation at capture is a live dependency, and swapping it means standing a replacement up beside it, watching both, then removing the old one. A gap in that cutover costs you leads you paid for.
What Xverify cannot do either
Questions people ask about Xverify
Is real-time validation different from bulk verification?
In timing and economics, yes. In protocol, no. The same SMTP conversation happens either way, and the same domains refuse to answer. What changes is that a real-time check has a user waiting, so it cannot retry a greylisted server the way a batch job can.
Is a fresh lookup worth three times the price?
It depends on where the list came from. A cached verdict can be months old, and mailboxes close in that window. Xverify runs the lookup live every time. On a bought list that gap is wide, and on your own subscribers re-checked quarterly it is narrow.
We have both problems, a form and a big list. Now what?
Then you need both behaviors and possibly one tool that does them. Ask each vendor about the real-time path and the bulk path separately, because plenty do one well and the other as an afterthought.
Is ZapBounce cheaper than Xverify?
At 100,000 addresses we list $139 and they list $400. 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.
Work out where your bad addresses arrive. A form and a purchased list are different problems and they are not solved by the same purchase.
