ColdLint
AI email detector for cold outreach
Highlight the lines that read like a model wrote them, then take the suggested edit. The detector is a fixed rule list, so the same email always gets the same score.
The verdict shows up here.
Scores run from rules on the server, so the same paste always lands in the same place. Nothing is sent to a model unless you later press Rewrite, and that button stays hidden until a key is configured.

What reads as generated
Cold email written by a model tends to open with a stock greeting, praise the company without naming anything, and close by asking for 15 minutes. The vocabulary repeats: delve, leverage, synergy, landscape, game-changer, seamless, robust, best-in-class. A stack of em dashes is its own tell.
One mild phrase does not fail the email. “I wanted to reach out” is a small hit. A paragraph that combines a fake compliment, a superlative, and a vague ask crosses into “do not send.” Each flagged line comes with a replacement: delete the opener, or swap the buzzword for a concrete noun.

Merge tags such as {{firstName}} are left alone. Broken ones, including single braces and [First Name], are flagged because they ship as literal text. That is a different failure from sounding generic, and it blocks a “ready to send” verdict on its own.
Scores do not call a model. Rewrite is a separate Pro action, and it only appears when the server has an API key. The prompt tells the model to keep your merge tags and not invent numbers or customer names.
For the rest of the pre-send check, including spam risk and the sending domain, use the main ColdLint checker.
