ZapBounce vs Verifalia
Verifalia does something unusual and worth crediting: it charges more for the addresses that are hard. Standard costs one credit, High two, Extreme four, and their own guidance says the higher levels are what you pick when you need a definitive answer on every row. Most of this category hides that cost in an average and prints a single rate.
| ZapBounce | Verifalia | |
|---|---|---|
| Accuracy figure published | Coverage and accuracy together, once measured | None published; they publish an uptime SLA instead |
| 1,000 addresses | $5 | $7.90 at Standard quality |
| 10,000 addresses | $25 | $49.90 at Standard quality |
| 100,000 addresses | $139 | $389 at Standard quality |
| Free tier | 100 a month, no card | 25 a day, recurring, resetting at midnight GMT |
| Credit expiry | Never | Purchased credits never expire; daily free credits expire each day |
| Billed for unknowns | No | Not stated |

How Verifalia prices it
A credit ladder from $7.90 a thousand to $4,890 at ten million, with a multiplier on top: Standard spends one credit an address, High two, Extreme four. The published price is a Standard price, so a deep clean of ten thousand addresses is four times the $49.90 headline. Purchased credits never expire; the daily free allowance does.
Where Verifalia is the better choice
Stated plainly, because a comparison page that never concedes anything is not worth reading.
- Their quality levels are the most honest pricing design in this category. Standard costs one credit, High two, Extreme four, and their own guidance says the higher levels are for when you need a definitive result on every address. That names the hard-address problem and prices it, instead of hiding it inside an average.
- The cheapest entry we found anywhere: $7.90 for a thousand at Standard, plus a free plan of 25 checks a day that renews forever.
- A governance surface deeper than most of this market ships: X.509 client-certificate auth, TOTP multi-factor, configurable data retention, a configurable firewall with trusted origins, granular team permissions and a published uptime SLA above 99.9%.
- They publicly disclosed that Yahoo verification broke for two days in April 2026 after a change at Yahoo's end. Posting your own outage is rare and it is evidence of how they operate.
Where we differ
What ZapBounce does differently
- We charge one rate per tier whatever the domain turns out to be, rather than asking you to choose a depth in advance.
- We never bill for unknowns. Their pages do not state a policy either way.
- We report coverage next to accuracy once measured. They publish uptime, which is a different promise entirely.

Moving off Verifalia
The quality-level arithmetic, once someone works it out. A list run at Extreme costs four credits an address, so $49.90 for ten thousand becomes closer to $200, and a team that set the default to Extreme and forgot is often surprised by the invoice rather than the verdicts.
The risk here is in your code, not your list. Anything switching on a detailed status has to be rewritten against a coarser vocabulary, and a switch statement with eight branches does not survive a move to four verdicts untouched.
What Verifalia cannot do either
Questions people ask about Verifalia
Which quality level should we compare on?
The one you actually run. Standard is one credit an address and the published price. High is two and Extreme is four, so a like-for-like against a vendor that pushes hard on catch-alls by default is arguably the Extreme price, not the headline.
Is $7.90 a thousand really the cheapest entry here?
At Standard quality, it is the cheapest we found, and their free plan of 25 a day renews indefinitely on top of it. At Extreme it is $31.60 for the same thousand addresses, which is a different conversation and the one their own guidance points serious cleaners toward.
They publish 99.9% uptime. Is that an accuracy figure?
No, and the two get confused constantly. Uptime is how often the service answers. Accuracy is whether the answer was right. Verifalia publishes the first and no figure for the second, which is the defensible choice in this category.
Is ZapBounce cheaper than Verifalia?
At 100,000 addresses we list $139 and they list $389 at Standard quality. 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.
