Is MillionVerifier Legit? Pricing, the 4% Guarantee and the Catches (November 2026)

Yes, MillionVerifier is legit. It is an established email verifier with public pricing, an API, published refund and guarantee terms, and a named operating company: its site lists Southern Vector Limited, registered in Christchurch, New Zealand, as of 2 November 2026. Its main draw is price. Packs run from 10,000 checks for $39 to 1,000,000 for $449, and its site says credits never expire. The catches are in the guarantee conditions and in the pricing model: there is no subscription, so every re-check of a list is bought again.

Everything below comes from MillionVerifier's own site and its guarantee page, with read dates. We sell a competing verifier, so we have stuck to what MillionVerifier publishes and made no claims about its accuracy.

What it costs

MillionVerifier sells one-time packs only. The full ladder was read from its pricing slider on 30 October 2026; the 50,000 and 1,000,000 prices were re-read and unchanged on 2 November.

Pack	Price	Per 1,000
10,000	$39	$3.90
25,000	$59	$2.36
50,000	$89	$1.78
100,000	$149	$1.49
500,000	$299	$0.60
1,000,000	$449	$0.45
10,000,000	$2,599	$0.26

The site also offers 100 free credits with no card. Two things follow from the table:

• Big, occasional cleans are cheap. A million addresses for $449, with credits that do not expire, is one of the lowest published per-address rates for a one-off job.
• The minimum is 10,000. If you verify 1,000 leads a week, you still buy a 10,000 pack. Because credits never expire, that is less painful than it sounds, but it is $39 up front.

Who is behind it

"Legit" usually means three things: a real company, real terms and a working product.

Check	What we found (2 Nov 2026)
Operating company	Southern Vector Limited, Christchurch, New Zealand, with its NZ business number on the site
Public pricing	Yes, every pack listed
Terms and guarantee	Published on its help centre
API	Yes, REST API with public documentation
Free trial	100 credits, no card

That is more than many smaller verifiers publish. It does not tell you how a given list will come out, which is why testing on your own data matters (see below).

The guarantee, in full

MillionVerifier's 100% money-back guarantee is the one buyers quote most often. Its help page sets these conditions:

Condition	MillionVerifier's terms
Trigger	Hard bounce rate above 4%
Which results count	Addresses marked "OK" only
Send window	Within 7 days of verification
Sender	A professional third-party sending service
Evidence	A detailed hard and soft bounce report, and access to your sending account
Not covered	Single API checks
Payout	Your last payment refunded

Unlike the ZeroBounce and Emailable guarantees, MillionVerifier's terms do not say the list must be opt-in. That makes it one of the few that a cold-email list can, in principle, qualify for. In practice, two conditions bite:

• Seven days is short for a sequence. If step 4 goes out three weeks after you verified, those sends are outside the window.
• Account access and a full bounce report are more than many sequencers make easy to hand over.

The payout is your last payment, not the cost of a damaged domain. Our bounce guarantee comparison puts these terms next to NeverBounce, ZeroBounce and Emailable.

The homepage also says MillionVerifier gives a "full refund on any email we can't verify with certainty", which reads as credits back for addresses it could not resolve. Several verifiers have a similar policy for unknown results, and it is a fair one. Ask support exactly which result types it covers before you count on it.

Why some people call it a scam

Search for MillionVerifier and you will find threads where a user ran the same address twice and got two answers, or saw an "OK" address bounce, and concluded the tool was fake. These complaints are understandable, but they are usually about how mail servers work, not about the vendor.

• Greylisting and rate limits. A server may defer the first check and answer the second. A verifier that sees a deferral has to say "unknown" or try again later.
• Catch-all settings change. A company can switch from accepting every address to rejecting unknown ones, or back, between two runs.
• Gateways answer for the server behind them. Some security gateways accept every recipient during the check and bounce later. See verifying emails behind security gateways.
• Mailboxes really do disappear. A person who left last week was valid then and bounces now.

Every SMTP verifier, including ours, has these limits. We explain them in detail in why the same email gets a different result and how to tell if your email verifier is lying.

When MillionVerifier is a good fit

• You clean big lists now and then. Low per-address cost and no expiry suit a quarterly or one-off clean.
• You want a simple product. Upload, verify, download. No suite to learn.
• You want a guarantee that does not require opt-in, and you can send within 7 days.

When something else may fit better

• You re-verify the same leads every month. Packs mean each pass is a new purchase. A flat monthly plan can cost less once you re-check regularly.
• You need more than verification. There is no inbox placement testing or blacklist monitoring in the same account.
• You verify very small batches. The 10,000 minimum is fine with no expiry, but a $9 plan may be a better fit for a few thousand a month.

Test before you trust any verifier

1. Take a sample of 200 to 500 addresses from a real list, including some you know bounced.
2. Run it through two or three verifiers, using their free credits.
3. Compare the splits: safe to send, risky, invalid and unknown.
4. Send a small batch of each tool's "safe" group from a warmed inbox and count the hard bounces.

Our bench test guide walks through doing this fairly, and the verifier comparison tool lines up published features side by side.

Where SimpleVerifier fits

SimpleVerifier runs a live mailbox check on each address and returns safe to send, send with care, check again later or do not send, with the reason. Catch-alls stay risky, never guessed valid, and each one gets a likelihood grade.

We sell both models. One-time packs never expire: 10,000 checks for $15, 25,000 for $29, 50,000 for $49, 100,000 for $79 and 250,000 for $169, CSV verification at standard speed. Monthly plans start at Starter, $9 a month for 2,500 emails, and Pro at $39 a month, which runs the first 100,000 checks a month at full speed, then slower, never cut off, with the API and email finder included. We offer no bounce guarantee, and fees are non-refundable once charged, so try the first 100 checks free with a Google sign-in on the verify page. See pricing.
