Movement

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

“Set up Google Postmaster Tools (free) and Microsoft SNDS (free). These are the only tools that provide direct, unvarnished reputation data” Gemini 3.5 Flash · Email deliverability · negative prompt · first choice

“Best free option: Stack Google Postmaster Tools, Microsoft SNDS, Yahoo Sender Hub, MXToolbox, Mail Tester, AboutMyEmail, and Sender Hub.” GLM 4.7 FlashX · Email deliverability · budget prompt · first choice

“free monitoring stack with Google Postmaster Tools, Microsoft SNDS, MXToolbox, and Yahoo Sender Hub” Perplexity Sonar · Email deliverability · budget prompt · first choice

“Pair it with a free tool like Google Postmaster Tools and Microsoft SNDS” DeepSeek V4 Flash · Email deliverability · paraphrase 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.

No model argued against it.

The products named in the same answers as Microsoft SNDS, over the 41 answers that named it. Took the first choice instead counts the answers where the other product was the first choice and Microsoft SNDS was named but was not.

What carried it into the answer

The sites and pages cited by the answers that named Microsoft SNDS. 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 41 of the 41 answers that named Microsoft SNDS and are not a share of its labels.

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

where Microsoft SNDS 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 Microsoft SNDS, 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.
