Write cold emails that don't sound like spam

“I need to reach new customers but my outreach gets ignored.”

AI can research each prospect and write a short, specific opener. Keep it human: you read and send each one, and follow anti-spam rules (honest subject, way to opt out).

Fix it yourself in 3 steps

  1. Pick 10 good-fit prospects and gather a public fact about each.
  2. Ask the AI for a 4-sentence email per prospect that mentions that fact and one clear ask.
  3. Edit and send yourself, in small batches, with an opt-out line.

Copy this prompt

Write a short cold email (under 90 words) to each prospect below. Use the one public fact I give for each, say plainly what I offer [offer], and end with one simple question. No fake familiarity, no false urgency, include an opt-out line. Prospects: [list with fact]. Don't send anything — stop after the drafts.

Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
