What the models said for it

Verbatim evidence the judge attached to positive labels.

“1-5 users, on-prem, minimal spend: MailStore Server Starter Kit at $259 one-time ... is the cheapest proven option.” Muse Glimmer 30B · Comms archiving · budget prompt · first choice

“For the tightest budget, start with MailStore Server (if you can handle on-premises) or Google Vault” MiniMax M2.5 · Comms archiving · budget prompt · first choice

“Start with Barracuda or MailStore if your needs are primarily email compliance and eDiscovery.” Kimi K2 · Comms archiving · direct prompt · first choice

“For most budget-conscious businesses, MailStore Server offers the best value.” Kimi K2 · Comms archiving · 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.

No model argued against it.

How it is countedHide how it is counted

Every page mailstore.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.

Names read as MailStore Server

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

where MailStore Server 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 MailStore Server, 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.
