Movement

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Postscript is a specialist tool that does only SMS incredibly well for online stores.” Qwen 3.7 Flash · Mobile & push · comparative prompt · alternative
“Shopify-only brands with real-time Shopify data integration ($49/mo minimum)” Mistral Small · Mobile & push · comparative prompt · alternative
“Klaviyo, Postscript, Omnisend | Built-in compliance, Shopify integration” Kimi K2 · Mobile & push · negative prompt · alternative
“SMS-first strategy | Postscript (Shopify) or Attentive (enterprise)” Kimi K2 · Ecommerce marketing · 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.

“Klaviyo, Postscript, Attentive are e-commerce/D2C-focused — skip.” DeepSeek V4 Flash · Mobile & push · direct prompt · hard negative
“What I'd skip ... Heavily e-commerce/DTC-centric (Shopify)” DeepSeek V4 Flash · Mobile & push · paraphrase prompt · hard negative

What carried it into the answer

The sites and pages cited by the answers that named Postscript. 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 2 of the 39 answers that named Postscript 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 Postscript'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 Postscript, 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 postscript.io 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.
