What the models said for it

Verbatim evidence the judge attached to positive labels.

“Built for marketers who want lookalike audiences, retargeting, and ROAS measurement on physical mail.” MiniMax M2.5 · Direct mail · comparative prompt · alternative
“Postie — performance/attribution-focused for retail/DTC; custom, strong incrementality testing.” DeepSeek V4 Flash · Direct mail · scale prompt · alternative
“Choose Postie if you care most about digital-style performance targeting and attribution” Perplexity Sonar · Direct mail · comparative prompt · alternative
“You treat mail as a performance channel with ROAS: → Postie” Qwen 3.7 Flash · Direct mail · 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.

“G2: 3.9/5 – the lowest-rated platform in this category” DeepSeek V4 Flash · Direct mail · negative prompt · hard negative
“High Costs: Costs add up depending on volume” GLM 4.7 FlashX · Direct mail · negative prompt · hard negative
“Users encountered problems with returned pieces that should have been scrubbed out before sending... reporting can lag and deposits are non-refundable” Claude Haiku 4.5 · Direct mail · negative prompt · soft negative
“Postie relies heavily on their team to manage the workflow ... Weak Attribution” Qwen 3.7 Flash · Direct mail · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Postie. 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 7 of the 26 answers that named Postie and are not a share of its labels.

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 Postie'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 Postie, 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 postie.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.
