Movement

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

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

“If you're a developer or need transactional + marketing email: SendGrid.” GLM 4.7 FlashX · Email marketing · budget prompt · alternative

“High-volume enterprise → Everest/Validity or SendGrid” DeepSeek V4 Flash · Email deliverability · comparative prompt · alternative

“SendGrid | High-volume/enterprise-scale sending” MiniMax M2.5 · Email deliverability · scale 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.

“Do not use these for TCM.” Qwen 3.7 Flash · Channel marketing · negative prompt · hard negative

“These are developer-focused. Choose this only if you have a strong engineering team ... Avoid if you want a user-friendly marketing tool.” Qwen 3.7 Flash · Email marketing · scale prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named SendGrid. 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 40 of the 47 answers that named SendGrid and are not a share of its labels.

How it is countedHide how it is counted

Every page sendgrid.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. Read October 5, 2026.

Names read as SendGrid

What the judge wrote, as written, with how often. The vendor table decides that these count as SendGrid; a claim can dispute any of them.

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

where SendGrid 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 SendGrid, 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.
