What the models said for it

Verbatim evidence the judge attached to positive labels.

“Sendoso, Postal, Reachdesk - Combine direct mail with broader sending and gifting motions” GLM 4.7 FlashX · Direct mail · comparative prompt · alternative
“It remains a highly user-friendly, marketplace-centric platform that is quick to set up” Gemini 3.5 Flash · Direct mail · direct prompt · alternative
“These blend direct mail into broader sending and gifting motions for sales and ABM.” MiniMax M2.5 · Direct mail · comparative prompt · alternative
“Postal (4.5/5) – gifting + direct mail with good ROI reporting” DeepSeek V4 Flash · Direct mail · negative 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.

“Systems log out every few hours... Can be pricey for frequent, high-volume sending” Kimi K2 · Direct mail · negative prompt · hard negative

What carried it into the answer

The sites and pages cited by the answers that named Postal. 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 4 of the 37 answers that named Postal 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 Postal'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 Postal, 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 postalytics.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.
