# MillionVerifier

MillionVerifier is a pay-as-you-go email verification service that checks addresses in bulk lists, through a real-time API, or via automated cleaning inside connected email platforms. Website: millionverifier.com. Category: [Email Infrastructure & Verification](https://gtmranked.com/best/email-deliverability/). Not enough independent evidence to rank (3 rated comments).

**Verdict:** Independent discussion is very thin: 20 of the 25 Reddit mentions are promotional, most of them a 2026 cluster of near-identical comments that name MillionVerifier only to steer readers to the same cheaper verifier, so this rests on three first-hand opinions. Those users agree it is cheap per verification, but one found bulk jobs very slow and another still had bounces hurting sender reputation after cleaning.

**What users like:**
- Low cost per verification: one user priced 50,000 credits at $77 against $245 for a pricier verifier, and another cites cost-effectiveness on large lists [1](https://www.reddit.com/r/Emailmarketing/comments/1bsft16/_/lwaledd/) [2](https://www.reddit.com/r/emailmarketingnow/comments/1hd76u1/_/m2b3uo1/)

**What users complain about:**
- Slow on bulk jobs: one tester waited about an hour for 2,000 emails that another verifier processed in two minutes [1](https://www.reddit.com/r/Emailmarketing/comments/1bsft16/_/lwaledd/)
- A user who cleaned a list with it still had bounces damaging their sender reputation [1](https://www.reddit.com/r/Emailmarketing/comments/17yeynu/_/k9u89mo/)

**Best for:** High-volume list cleaning where cost per check matters most.
**Skip it if:** Time-sensitive bulk verification jobs.
**Pricing (vendor-stated, checked 2026-10-14):** Pay-as-you-go credits with no contracts, from $39 (smallest pack size not stated on the page); 50,000 verifications for $89 and 1 million for $449. Credits never expire; 100 free credits with no card required; refunds for emails it can't verify with certainty.
