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.

“The best email verification service for a mid-market B2B company is ZeroBounce, as it offers the best balance for mid-market list cleaning.” Llama 4 Maverick · Email verification · direct prompt · first choice
“ZeroBounce (The Premium, Feature-Rich Suite) ... Best For: Enterprise teams needing a complete email deliverability and analytics toolkit.” Gemini 3.5 Flash · Email verification · comparative prompt · first choice
“NeverBounce and ZeroBounce are the most recommended for their accuracy, ease of use, and feature sets.” Mistral Small · Email verification · direct prompt · first choice
“ZeroBounce is likely your best starting point due to its accuracy, integrations, and balanced feature set.” Claude Haiku 4.5 · Email verification · paraphrase 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.

“ZeroBounce only handles the list side of deliverability, not the content or infrastructure side.” Claude Haiku 4.5 · Email deliverability · negative prompt · hard negative
“NeverBounce and ZeroBounce - While popular, tests show they can produce different results for the same emails” Kimi K2 · Email deliverability · negative prompt · soft negative
“Avoid tools that are just list cleaners (ZeroBounce, Clearout) unless you only need one-off hygiene.” Kimi K2 · Email deliverability · scale prompt · soft negative
“enterprise tools like GlockApps ($85+/month) or ZeroBounce ($99/month) would cost” DeepSeek V4 Flash · Email deliverability · budget prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named ZeroBounce. 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 203 of the 223 answers that named ZeroBounce and are not a share of its labels.

Most recent

How it is countedHide how it is counted

Every page zerobounce.net 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. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person.

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 ZeroBounce'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 ZeroBounce, 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 ZeroBounce by email, built from the raw record of the edition. It shows:

  • where ZeroBounce 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 ZeroBounce, 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 zerobounce.net 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.
