MillionVerifier draws about 1,200 searches a month in India, and another 450 for “million verifier.” The reason is simple: it is one of the lowest-cost verifiers on the market, and cost matters when you are cleaning lists in lakhs rather than thousands.
But low price per credit is only half the equation. The other half is what an inaccurate “valid” label costs you in bounces, blocked domains, and wasted SDR time. This review examines both sides so you can decide whether MillionVerifier fits your list and your risk tolerance.
What MillionVerifier Does
MillionVerifier is a standalone bulk verification service. You upload a CSV or call its API, and it classifies each address as good, risky, or bad, with flags for disposable and role-based addresses.
It also offers EverClean, an automated service that re-verifies connected lists on a schedule. There is no email finder, no enrichment, and no sending. Like NeverBounce, it grades the list you bring.
Pricing and the Never-Expiring Credit Model
MillionVerifier’s public packs start at about 10,000 credits for $37 to $39, with occasional smaller trial packs for new users. Per-email cost falls steeply with volume; independent 2026 analyses put 50,000 checks at around $89 and 1 million at a few hundred dollars.
At the 10,000 tier, that is roughly ₹0.33 per email, less than half of NeverBounce’s entry rate.
The more important feature is that credits never expire. For Indian teams that verify in bursts, such as an edtech company cleaning leads before an admissions cycle or an agency onboarding a new client, this removes the pressure to spend credits before a deadline.
BounceProof follows the same principle: credits that never expire, one credit per check, whatever the result, and no per-seat charges when your whole team verifies from one pool.
The Risky-Email Refund: How It Works
MillionVerifier refunds credits for addresses it cannot classify with confidence and marks as risky, which includes most catch-all results. You only pay in full for good and bad verdicts.
This sounds like a pure win, and financially it often is. But read it carefully:
- The refund compensates you for an unresolved result. It does not resolve it.
- On an enterprise-heavy B2B list, a large share of addresses can end up in the risky bucket.
- You still have to decide what to do with those contacts, and that decision carries the real deliverability risk.
A refund on uncertainty is a pricing feature, not an accuracy feature.
Accuracy and the Catch-All Problem
MillionVerifier claims 99%+ accuracy. Independent tests in 2026 report real-world accuracy nearer 95 to 96% on mixed lists, with weak resolution of catch-all domains.
One published benchmark across 251 enterprise catch-all domains found a large share of records left unresolved and a double-digit false-positive rate on deliberately fictional addresses. Methodologies vary, so treat any single benchmark cautiously. The pattern, however, is consistent: budget verifiers perform well on consumer and SMB domains and struggle where corporate mail servers accept everything.
Why this matters for Indian B2B lists
Indian IT services firms, BFSI companies, and large enterprises frequently route mail through Microsoft 365 or Google Workspace with gateway filtering. Many of these respond as accept-all. If your ideal customer profile is the Indian enterprise buyer, a large portion of your list will sit exactly where cheap verification is weakest.
Our guide to catch-all email addresses covers how to segment and send to these contacts safely.
Which Indian Teams It Suits
MillionVerifier is a strong fit when:
- Your list is mostly consumer addresses (Gmail, Yahoo, Outlook.com, Rediffmail).
- You are scrubbing a large, old database for obvious hard bounces before re-engagement.
- Budget is the primary constraint,nt and you can tolerate some residual bounce risk.
- You verify irregularly and value non-expiring credits.
For a D2C brand with 5 lakh newsletter subscribers collected over four years, a low-cost first pass that removes dead addresses is sensible and economical.
Where It Falls Short
- Enterprise B2B prospecting, where catch-all resolution determines outcomes.
- Workflows that need collaboration: shared histories, team credit pools, and real-time progress visibility.
- Support. G2 reviews repeatedly praise price and speed but flag slow help when something goes wrong.
- USD billing, which adds forex costs and procurement friction for Indian finance teams.

A simple way to decide
Run a three-way test. Take 1,000 recent contacts from your real list. Verify them with two or three tools. Send only to addresses each tool marked valid, in small separate batches, and compare hard bounce rates after 48 hours. The tool with the lowest bounce rate on your data wins, regardless of its price per credit.
Key Takeaways
- MillionVerifier is among the cheapest verifiers, at roughly $37–39 per 10,000 credits.
- Credits never expire, which suits campaign-driven Indian teams.
- The refund on risky results reduces cost but leaves those contacts unresolved.
- Independent tests show weaker performance on enterprise catch-all domains.
- It suits consumer and SMB lists; enterprise B2B lists need stronger catch-all handling.
- Always judge verifiers on post-send bounce rates from your own data.
Frequently Asked Question
Yes. It is an established verification service with a large G2 review base and ISO 27001 certification. Its trade-offs are about accuracy on difficult domains and support responsiveness, not legitimacy.
No. Purchased credits remain available indefinitely.
Risky usually means the domain is a catch-all or the server did not give a conclusive answer. Enterprise B2B lists contain many such domains, so the risky share rises.
It works for SMB and consumer-heavy lists. For enterprise prospecting, pair it with a stricter catch-all strategy or use a verifier with stronger risk classification. Our cold email list hygiene guide explains the segmentation.
It works through CSV upload and integrations. Tools that run directly inside Google Sheets avoid the export and re-import step.
Conclusion
MillionVerifier earns its reputation as the budget choice, and for large consumer lists it is often the most economical first pass. Where it becomes expensive is not on the invoice but in the inbox: the enterprise contacts it cannot resolve are frequently the ones your pipeline depends on.
Choose it deliberately. If most of your revenue comes from Indian enterprise accounts, cheap verification is a false economy unless you pair it with disciplined catch-all handling. If your list is consumer-heavy and your goal is removing dead weight, it is hard to beat on price.
