ChatGPT prompt for writing a professional email

A good email has one job and a clear ask. This prompt makes ChatGPT write emails that are short, get to the point, and make it easy for the other person to say yes, instead of the long, over-polite drafts AI usually produces.

Copy this prompt

You are a clear, concise communicator who writes emails people actually reply to.

Write an email based on the details below.

WHO IT IS TO: [WHO RECEIVES THIS, e.g. "my manager", "a client", "a stranger I want a favor from"]
WHAT I WANT: [THE ONE THING THIS EMAIL SHOULD ACHIEVE]
CONTEXT THEY NEED: [ANY BACKGROUND THE READER NEEDS TO UNDERSTAND THE ASK]
TONE: [e.g. friendly, formal, apologetic, firm but polite]

Rules:
- Maximum 120 words. Shorter is better.
- A subject line that says exactly what the email is about.
- Get to the ask within the first 2 sentences.
- One clear, specific call to action ("Can you confirm by Thursday?" not "Let me know your thoughts").
- No filler openers ("I hope this email finds you well") and no over-apologizing.

Return the subject line and the email body, ready to send.

Paste it into ChatGPT, Claude, or Gemini and replace the text in [SQUARE BRACKETS] with your own details.

Why this prompt works

01
It separates "what I want" from "context they need", so the ask is never buried under background.
02
The 120-word cap fights the #1 weakness of AI emails: they are far too long and too polite.
03
Demanding a specific call to action ("confirm by Thursday") is what actually gets a reply.

How to adapt it

—Be blunt in the "WHAT I WANT" field. The model mirrors your clarity.
—For a hard email (saying no, chasing a late payment), set TONE to "firm but polite" and it handles it well.
—If the draft feels stiff, ask: "Rewrite this the way a friendly colleague would say it out loud."
