Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.

The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“PostGrid and Lob are strongest for pure direct mail automation, with PostGrid favored for API-centric workflows and Lob for marketing team usability.” MiniMax M2.5 · Direct mail · comparative prompt · first choice
“PostGrid is the safest "best direct mail automation platform" pick for a mid-market B2B company” Perplexity Sonar · Direct mail · direct prompt · first choice
“with PostGrid and Lob most often cited for API-first print-and-mail automation” Perplexity Sonar · Direct mail · comparative prompt · first choice
“choose Lob/PostGrid for programmatic, high-volume, developer-integrated mail” Muse Glimmer 30B · Direct mail · comparative 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.

“here are the direct mail automation platforms you should avoid or approach with caution... 2. PostGrid ... Faulty tracking” Kimi K2 · Direct mail · negative prompt · hard negative
“Postgrid is frequently cited in reviews for having significant operational flaws, leading to a low Trustpilot rating of 2.9/5.” GLM 4.7 FlashX · Direct mail · negative prompt · hard negative
“Platforms to Approach with Caution or Avoid: PostGrid ... Best Avoid If: You need reliable support, tracking, or non-US mailing.” Grok 4.20 · Direct mail · negative prompt · hard negative
“Avoid pure mail-only (e.g., Lob, PostGrid) if gifting is key.” Grok 4.20 · Direct mail & gifting · direct 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, five of the fourteen in this edition, so these counts come from 168 of the 170 answers that named PostGrid and are not a share of its labels.

Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

How it is countedHide how it is counted

Every page postgrid.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read September 29, 2026.

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 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.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for PostGrid by email, built from the raw record of the edition. It shows:

  • where PostGrid is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name PostGrid, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at postgrid.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
