Side by side
How they compare
What matters when you choose a verifier.
| SimpleCold |  MillionVerifier | |
|---|---|---|
| Result categories | Deliverable, Risky, Undeliverable (Processing while a slow server answers) | ok, catch_all, unknown, invalid, disposable |
| Reason with each result | A statusMessage sentence on every result | A result plus a subresult code; no written reason |
| Catch-all addresses | Flagged Risky within the normal credit. No paid step to resolve them | Flagged catch_all. Extra catch-all testing at no extra cost, which it says resolves about 30 to 40% |
| Addresses the server won't confirm | Processing first, then the final result. If the server never confirms: Risky (status no_response), one credit used | Not charged: credits for catch_all and unknown results are returned |
| Typo suggestions | Yes (suggestion) | Yes (didyoumean) |
| CSV keeps your columns | Yes, with your exact headers. Readable result columns appended; duplicate rows removed and not charged | Yes (XLSX uploads are limited to 20 columns) |
| API | Real-time single checks, batches of up to 50 and bulk CSV upload | Real-time single checks and a bulk file API; no batch JSON endpoint documented |
| Pricing model | One-off purchases from 5,000 credits, $0.005 down to $0.00125 per check. No subscription | One-time credit packs from $39 for 10,000, with optional auto top-up |
| 10,000 checks | $40 | $39 |
| 100,000 checks | $200 | $149 |
| Free to start | 200 credits on sign-up, no card | 100 credits, no card |
| Credit expiry | Credits don't expire | Never expire |
