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.

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.
Why teams pick ZapBounce over Verifalia
What changes when your list runs through ZapBounce instead.
The short version
- Lower than their Standard level at every tier: $5 against $7.90 for 1,000, $25 against $49.90 for 10,000, and $139 against $389 for 100,000.
- One depth, one price. Their High and Extreme levels spend two and four credits an address; a ZapBounce check is one credit whatever the domain turns out to be.
- Unknowns are never billed. Their pages do not state a policy either way.
- Coverage reported next to the verdicts. They publish uptime, which is a different promise entirely.
- A closed vocabulary of four results with a documented reason list, so code that branches on a result stays short.
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 work here is in your code, not your list. Map each status you branch on to one of four ZapBounce results, and read the reasonCode field for the detail behind each one. A switch statement with eight branches becomes four, and a small test list shows how the rewrite behaves.
The hard addresses, and how they come back
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.
What does $7.90 a thousand buy?
A thousand checks at Standard quality, with a free plan of 25 a day beside it. At Extreme the same thousand costs $31.60, which is the level their own guidance points serious cleaners toward. A ZapBounce thousand is $5, one credit an address whatever the domain.
Verifalia publishes 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: 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.
