What the models said for it

Verbatim evidence the judge attached to positive labels.

“PostGrid is best for revenue ops teams needing API-driven direct mail triggered by CRM events (rated 9.3/10 overall)” MiniMax M2.5 · Direct mail · comparative prompt · first choice
“Choose PostGrid or Lob if you want API-first, developer-controlled automation” Perplexity Sonar · Direct mail · comparative prompt · first choice

“For a typical mid-sized B2B company, I'd suggest PostGrid” MiniMax M2.5 · Direct mail · paraphrase prompt · first choice

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.

“Avoid Lob ($260-$550/month) and PostGrid unless you need API-first development capabilities” Kimi K2 · Direct mail · budget prompt · hard negative
“Platforms to Avoid or Be Cautious About ... 1. Postgrid - Poor Customer Support” GLM 4.7 FlashX · Direct mail · negative prompt · hard negative

What carried it into the answer

The sites and pages cited by the answers that named PostGrid. 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 20 of the 110 answers that named PostGrid 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 PostGrid'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 PostGrid, 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 postgrid.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.
