What the models said for it

Verbatim evidence the judge attached to positive labels.

“MailReach is the best budget option for warmup and placement testing bundled into one affordable plan” Claude Haiku 4.5 · Email deliverability · budget prompt · first choice
“or MailReach (warm‑up + testing at a lower price)” GLM 4.7 FlashX · Email deliverability · direct prompt · first choice
“MailReach is the best overall choice in 2026” DeepSeek V4 Flash · Email deliverability · direct prompt · first choice
“Primary Recommendation: MailReach” MiniMax M2.5 · Email deliverability · 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.

“The tool may not accurately reflect deliverability for all B2B scenarios, so approach with caution if your audience is large or uses corporate email systems.” Mistral Small · Email deliverability · negative prompt · soft negative
“Tools like GlockApps, MailReach, and Mailtrap vary in real-time validation depth — only some verify addresses at scale before sending.” Muse Glimmer 30B · Email deliverability · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named MailReach. 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 62 of the 62 answers that named MailReach and are not a share of its labels.

How it is countedHide how it is counted

Every page mailreach.co 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. Read October 5, 2026.

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 MailReach'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 MailReach, 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 MailReach by email, built from the raw record of the edition. It shows:

  • where MailReach 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 MailReach, 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 mailreach.co 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.
