What the models said for it

Verbatim evidence the judge attached to positive labels.

“Warmup Inbox ($12/mo per inbox): For warming new domains.” Grok 4.1 Fast · Email deliverability · budget 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.

“Avoid relying on these for core deliverability.” DeepSeek V4 Flash · Email deliverability · negative prompt · hard negative
