VeriMails vs MillionVerifier
MillionVerifier publishes low high-volume credit packs, a no-card free account flow, fast bulk targets, a real-time API, and a clear policy that catch-all and unknown results are risky but not charged. The practical comparison is less about whether MillionVerifier works and more about which workflow, billing model, and volume band fits your team.

MillionVerifier Pricing Reference
MillionVerifier publishes a broad credit-pack calculator, so the price comparison depends on both list size and how many results fall into chargeable categories.
Pricing and Billing Policy
The MillionVerifier pricing screenshot captured May 19, 2026 shows credit packs from 2,000 to 50,000,000 credits. For the common comparison points, listed packs include $39 for 10,000 credits, $149 for 100,000, $299 for 500,000, and $449 for 1,000,000. VeriMails remains cheaper at the 10,000 and 100,000 public packs. MillionVerifier becomes cheaper at 500,000 and 1,000,000 before considering risky-result billing. Confirm the current MillionVerifier calculator before purchase.

| 1,000,000 emails | $499 | $449 | MillionVerifier lower public pack price |
These rows compare listed credit pack purchase prices captured May 19, 2026. MillionVerifier's effective credit consumption may be lower when a list contains catch-all or unknown results, because those risky results are not charged.
MillionVerifier credit tiers
| MillionVerifier credits | Official pack price | Computed price per listed credit |
|---|---|---|
| 2,000 | $4.90 | $0.00245 |
| 10,000 | $39 | $0.0039 |
| 25,000 | $59 | $0.00236 |
| 50,000 | $89 | $0.00178 |

| 500,000 | $299 | $0.000598 |
| 1,000,000 | $449 | $0.000449 |
The May 19, 2026 calculator screenshot and MillionVerifier's bulk-verifier service page both supported the $149 at 100,000 and $449 at 1,000,000 figures. A separate older homepage marketing sentence still mentioned $389 for 1,000,000, so confirm the current calculator before buying.

Catch-all and Unknown Handling
MillionVerifier describes a dedicated catch-all verifier, not just a binary catch-all label. The feature is already active, runs automatically, and keeps the dashboard, API, and overall workflow the same. The catch-all guide says it can reduce catch-all and business unknown results by up to 70-80%, while keeping uncertain emails classified as catch-all for safety.
The tradeoff is timing and decision-making. MillionVerifier says deeper catch-all checks usually take 10-30 seconds and some providers may take up to 60 seconds. VeriMails is the more focused fit when teams want a straightforward verification workflow with catch-all segmentation surfaced clearly before campaign or CRM import decisions. MillionVerifier is compelling when the risky-result billing policy and automated catch-all upgrade matter more than a simpler product surface.
Ok emails are safe to send according to MillionVerifier's result guide.
Invalid and Disposable emails are not safe to send and are billable in MillionVerifier's policy.
Catch-all and Unknown can be usable only with care, and MillionVerifier says these results are not charged.
| Result or policy | MillionVerifier | Buyer impact |
|---|---|---|
| Catch-all | Server accepts mail broadly, even for addresses that may not exist | Risky to send without segmentation or recent opt-in context |
| Unknown | Verifier could not determine whether the mailbox exists at verification time | May be reverified later; avoid treating it like a normal valid result |
| Billing | Only Ok, Invalid, and Disposable are charged; Risky results are not charged | Lists with many catch-all or unknown results can consume fewer credits than the raw row count |
| Catch-all verifier | Automatic, no workflow changes, beta, no additional catch-all fee | Useful for reducing uncertain results, but still requires policy decisions on risky emails |
Bulk and API Workflow
MillionVerifier supports more than manual CSV upload. Its public help center lists six verification paths: file upload, copy-paste lists, single email checks, integrations, API, and automated email list cleaning. For file upload, it accepts TXT, CSV, XLS, and XLSX files. CSV uploads can include up to 1 million rows, the file-size limit is 100MB, and MillionVerifier says it charges only for unique emails in the uploaded file.
The real-time single API is positioned for signup and app workflows, with an account-specific rate limit of 160 requests per second. The API reference exposes result values for ok, catch_all, unknown, error, disposable, and invalid, plus fields such as quality, result code, subresult, free-domain flag, role flag, typo suggestion, remaining credits, and execution time. The bulk API covers upload, file info, file list, download, stop, and delete flows.
| Workflow | MillionVerifier public behavior | What to watch |
|---|---|---|
| Dashboard bulk upload | TXT, CSV, XLS, XLSX; automatic email-column detection; unique emails only charged | CSV row limit is 1 million; XLSX row limit is 150,000 and column limit is 20 |
| Bulk speed | 3,000 emails/minute plus re-verification; 1M about 6 hours | Files mostly from one or two domains may be slowed by 90% |
| Single API | Real-time API, 160 requests/second account-specific limit, risky results not deducted initially | Repeated API checks of the same billable email are charged again |
| Bulk API | Programmatic upload, status, list, download, stop, and delete endpoints | Build around file IDs, async status, and result downloads |
| Stopped jobs | Already verified rows are returned; unverified rows are marked unknown and credits are refunded for those | Downstream systems should handle unknown rows separately |
Who Should Choose Which?
Choose VeriMails if
You want lower purchase prices at 10,000 and 100,000 credits, a focused verification product, bulk list cleaning without a broader automation platform, and catch-all segmentation that is easy to explain to sales, marketing, or CRM operators.
Choose MillionVerifier if
You verify very large lists, expect many catch-all or unknown results, need existing ESP integrations, want EverClean automation, or specifically value the policy that risky catch-all and unknown results are not charged.

Verification Accuracy
Both VeriMails and MillionVerifier can help reduce bad addresses before a campaign. The difference is how clearly the result fits your next send: VeriMails keeps valid, invalid, disposable, role-based, catch-all, and unknown rows separate for decision-making.
Use a recent sample from your own CRM, not a perfect test list. The addresses that matter are the ones you plan to mail this week: old leads, imported contacts, role inboxes, catch-all domains, and records from mixed sources.
Who VeriMails Is Best For
Choose VeriMails when verification is the job and you want the result before the send.
- You already have a list and need to clean it before a campaign.
- You want prepaid verification credits that never expire.
- You need API and CSV verification without paying for a larger sales platform.
