Movement

What the models said for it

Verbatim evidence the judge attached to positive labels.

“If you want flexibility, look into "notification infrastructure" platforms (such as Courier or Knock).” Gemini 3.5 Flash · Mobile & push · negative prompt · first choice

“Choose Courier if you are building product notifications and need developer-friendly cross-channel infrastructure” Perplexity Sonar · Mobile & push · comparative prompt · alternative

“Courier is the clearest fit in the results... one API covers push, email, SMS, in-app inbox, Slack, and Microsoft Teams” Perplexity Sonar · Mobile & push · direct prompt · alternative

“Courier is an API-first product notification engine that coordinates messages across channels” Gemini 3.5 Flash · Mobile & push · 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.

No model argued against it.

A head-to-head page exists where both products are in a category's top three. 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 Courier. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 15 of the 63 answers that named Courier 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 Courier'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 Courier, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at courier.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
