Why people look elsewhere
Small batches, mostly. The smallest pack MillionVerifier publishes is 50,000 addresses for $89 (read 24 September 2026), so a team cleaning a few thousand signups a month buys far ahead of its need. ZapBounce sells 1,000 checks for $5 and 10,000 for $25, with credits that never expire.
Pay-as-you-go only, with credits that never expire. MillionVerifier publishes two packs on its homepage: $89 for 50,000 and $449 for a million. ZapBounce's ladder runs from $5 for 1,000 through $89 for 50,000, and a monthly plan costs 15% less than the same credits pay-as-you-go.
What ZapBounce changes for a MillionVerifier user
The differences that show up on the first invoice and the first results file.
The short version
- Unknowns and duplicates are never billed, and both rules are printed on our pricing page.
- Coverage reported beside the verdicts on every list, rather than a single 99%+ headline.
- Every tier on one pricing page, from 1,000 addresses to a million.
- A $5 entry for 1,000 checks, with no minimum, for the small batches that arrive between big cleans.
- A monthly free allowance of 100 credits, so small top-up checks between big files cost nothing.
Before you move off MillionVerifier
Run the same sample through two vendors and the interesting number is not how many came back valid.
Size your usual batch
If most files are under 50,000 addresses, price them at ZapBounce's $5 for 1,000 or $25 for 10,000 instead of buying a 50,000 pack ahead of need.
Map resolved catch-alls to catch_all
Rows their catch-all service resolved come back from ZapBounce as catch_all. Decide how each segment mails those before the first upload.
Set a retention window you can name
Pick how long your lists should live, delete finished jobs with DELETE /v1/jobs/{id}, and write the rule into your data processing record.
Test on 100 free credits
ZapBounce gives 100 free credits on signup and 100 more every month, no card. Run a sample MillionVerifier already checked and compare the unknown rows.
What switching actually involves
Standard CSV in and CSV out. MillionVerifier's catch-all service bills a credit only when it resolves an address, and says it converts up to 40% of catch-alls. ZapBounce runs one probe per catch-all domain and returns catch_all, billed once, so any rule that reads their resolved rows moves to our catch_all result.
What stays true whichever verifier replaces MillionVerifier
Questions about moving off MillionVerifier
Does MillionVerifier charge for unknown results?
No. Its catch-all page says unresolved addresses aren't charged, and unknowns cost nothing (read 24 September 2026). ZapBounce applies the same rule to unknowns and to duplicates, and prints it on its pricing page.
What does ZapBounce charge below 50,000 addresses?
$5 for 1,000 and $25 for 10,000. MillionVerifier's smallest published pack is 50,000 for $89, which is the same price ZapBounce charges at that volume.
How long does each vendor keep our list?
MillionVerifier's privacy policy keeps data for as long as necessary, with no per-list number. ZapBounce lets you delete a job at once with DELETE /v1/jobs/{id}.
Why do people leave MillionVerifier?
Small batches, mostly. The smallest pack MillionVerifier publishes is 50,000 addresses for $89 (read 24 September 2026), so a team cleaning a few thousand signups a month buys far ahead of its need. ZapBounce sells 1,000 checks for $5 and 10,000 for $25, with credits that never expire.
How hard is it to switch verifiers?
For bulk cleaning, no harder than uploading the file somewhere else. For real-time checks on a signup form it is an API swap, which is an afternoon.
If your batches run under 50,000 addresses, ZapBounce's $5 and $25 tiers fit them without buying ahead.
