Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.

The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Choose MillionVerifier if you have a very large list (e.g., 10k+) to clean at once and want the lowest bulk price.” Qwen 3.7 Flash · Email verification · budget prompt · first choice
“MillionVerifier – Best Overall Value ... If you need the absolute lowest cost: Go with MillionVerifier” DeepSeek V4 Flash · Email verification · budget prompt · first choice
“Start with MillionVerifier – 100 free credits to test, then pay-as-you-go with no expiration” Kimi K2 · Email verification · budget prompt · first choice
“For most budget-conscious companies, I'd start with MillionVerifier for bulk list cleaning.” GPT-6 Luna · Email verification · budget prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“MillionVerifier is the one most often singled out with documented false positives and billing complaints — proceed with caution there.” DeepSeek V4 Flash · Email verification · negative prompt · hard negative
“MillionVerifier and EmailListVerify offer the lowest cost per 10k emails but lack advanced deliverability features” Muse Glimmer 30B · Email verification · budget prompt · soft negative
“Budget/low-cost options like EmailListVerify, MillionVerifier, and DeBounce - Approach with caution” Grok 4.20 · Email verification · negative prompt · soft negative
“Best on a tight budget, with a price of ~$6/10K, but with lower catch-all accuracy.” Llama 4 Maverick · Email verification · paraphrase prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named MillionVerifier. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 52 of the 53 answers that named MillionVerifier and are not a share of its labels.

Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

How it is countedHide how it is counted

Every page millionverifier.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. Read September 29, 2026.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when MillionVerifier's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as MillionVerifier, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for MillionVerifier by email, built from the raw record of the edition. It shows:

  • where MillionVerifier is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name MillionVerifier, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at millionverifier.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
