Movement

This is the first edition on this tier, so no move can be computed for Mailgun 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

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.

“Mailgun offers a RESTful Email API and SMTP integrations, with dedicated IP addresses and inbox placement testing via Mailgun Optimize.” Claude Haiku 4.5 · Email deliverability · comparative prompt · alternative

“Services that consistently rank top-tier... ZeroBounce, Debounce.io, Mailgun, NeverBounce, and Kickback.ai” Qwen 3.7 Flash · Email verification · negative prompt · alternative

“Alternative: Mailgun ... often more expensive than a dedicated testing tool like GlockApps” GLM 4.7 FlashX · Email deliverability · paraphrase prompt · alternative

“E-commerce/Transactional → Mailgun or SendGrid with built-in deliverability tools” Kimi K2 · Email deliverability · comparative prompt · alternative

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.

“The user interface is widely described as dated and unchanged for years.” DeepSeek V4 Flash · Email deliverability · negative prompt · soft negative

What carried it into the answer

How it is countedHide how it is counted

Every page mailgun.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.

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

where Mailgun 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 Mailgun, 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.
