What are the most common cold email mistakes that make people delete on sight?

A starting point

The killers are predictable: a wall of text, making it about you instead of them, a vague ask (let's hop on a call sometime), and a first line that screams mail merge. Attachments, multiple links, and a pitch before any relevance also trigger instant delete. Almost every bad cold email fails the same test: the reader can't tell in two seconds why this matters to them. As a starting point, cut your draft in half, delete the second paragraph about your company, and make the ask a single easy yes.

10 Cold Email Mistakes Founders Still Make (And How to Fix Them)

From Polymail Blog by Pulin Thakkar ~8 min read

Writing like a brochure instead of a human, and over-formatting with logos and buttons, both read as automated and get deleted.
About 80 percent of replies come after the second touch, so sending one email and stopping is the quiet mistake most founders make.
Weak or confusing calls to action create friction, keep the ask small and clear enough to answer in one line.

Why we picked it Josh Braun spends his days tearing down cold emails, and here he flips the frame: he takes apart one real email that survived his delete finger and explains, line by line, why it worked and where it still fell short. Reading why a single email earned a reply makes the lessons stick harder than any list of do-nots.

A Cold Email I Didn't Delete

From joshbraun.com by Josh Braun ~6 min read

Acknowledgement, relevant context tied to something recent, a quantified benefit, and matched social proof are what stop the delete.
Bury your strongest number (like a 32 percent result) too late and you lose the reader before they reach it.
Asking for too little (a vague 5 minutes) with no calendar link and no follow-up quietly kills otherwise good emails.
