Movement

This is the first edition on this tier, so no move can be computed for GlockApps yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated GlockApps across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“For most mid-sized B2B companies, GlockApps offers the best balance of comprehensive diagnostics, B2B-appropriate seed lists, and reasonable pricing.” Claude Haiku 4.5 · Email deliverability · paraphrase prompt · first choice

“the best choice is usually GlockApps if you want the strongest balance of inbox placement testing, DMARC monitoring, and mid-market pricing” Perplexity Sonar · Email deliverability · direct prompt · first choice

“For most mid-sized B2B companies, GlockApps is the best choice due to its depth of inbox placement testing and deliverability diagnostics.” Mistral Small · Email deliverability · paraphrase prompt · first choice

“Check where your emails land (Inbox vs. Spam) | GlockApps | Sends to 100+ real seed mailboxes to give exact placement stats.” Gemini 3.5 Flash · Email deliverability · comparative 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.

“GlockApps became popular for one specific capability... Test credits do not roll over... stops at telling you what is wrong.” Muse Glimmer 30B · Email deliverability · negative prompt · soft negative

“a fraction of what enterprise tools like GlockApps ($85+/month) or ZeroBounce ($99/month) would cost” DeepSeek V4 Flash · Email deliverability · budget prompt · soft negative

“Good for deeper testing, but pricier; consider only if you have repeated deliverability issues” GLM 4.7 FlashX · Email deliverability · budget prompt · soft negative

“recommended over paid tools like GlockApps ($59+/mo)” Grok 4.1 Fast · Email deliverability · budget prompt · soft negative

A head-to-head page exists where both products are among a category's top eight. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named GlockApps. 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 148 of the 153 answers that named GlockApps and are not a share of its labels.

How it is countedHide how it is counted

Every page glockapps.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. 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. Read October 5, 2026.

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

where GlockApps 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 GlockApps, 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.

Badges

Wins only: a badge exists where GlockApps is ranked in a category's top three this edition. Three sizes, one file each, light and dark; the code is under each.
