ChatGPT Prompts for Work Emails (Copy-Paste)

The most useful ChatGPT prompts for work emails do one small job each: summarize a long thread, draft a reply, decline politely or make a request clearer. Copy a prompt below, fill in the parts in [brackets], paste in the email, then read and edit the draft before you send it. The prompts work in ChatGPT, Claude, Gemini and Microsoft 365 Copilot.

Which AI tool to use for work emails

Start with the tool your employer has approved. Company rules on AI and confidential data come first, and an approved tool is usually set up to protect work content.

Microsoft 365 Copilot in Outlook can help with messages in your mailbox, where your workplace includes it.
Gemini in Gmail can help with messages in your inbox, where your Google Workspace account includes it.
ChatGPT and Claude are general chat assistants. They can't see your inbox, so you paste in the email you want help with.

The prompts below work in all four. In a connected tool you can often skip the "paste the email here" line.

How to write a good email prompt

A short prompt with clear instructions beats a long, vague one. Include:

The email. Paste the message or thread, or point a connected tool to it.
The job. Summarize, reply, decline, rewrite or follow up.
The limits. Tone (warm, neutral or formal), length (for example, under 80 words) and anything that must be included.

If the first draft isn't right, say what to change: "Shorter", "Less formal" or "Mention the Friday deadline". Small corrections work better than starting over.

7 ChatGPT prompts for work emails

Replace everything in [square brackets] before you use a prompt.

1. Summarize an email thread with AI

For a long thread you've just been added to.

Summarize this email thread in five bullet points. What has been decided, what is still open, and what is expected from [your name or role]?

[paste the thread here]

Use the AI tool your employer has approved. In public tools, remove names, numbers and anything confidential. Read every draft before you send it.

2. Draft a reply

For when you know the answer but not the words.

Draft a short, friendly reply to this email. The reply should [say yes / suggest a new time / ask for more details about X]. Keep it under 80 words. Tone: [warm / neutral / formal].

[paste the email here]

Use the AI tool your employer has approved. In public tools, remove names, numbers and anything confidential. Read every draft before you send it.

3. Polite decline email

For a request you can't take on right now.

Write a polite reply that declines this request. Reason: no capacity until [date or month]. Offer [a colleague who could help / a later date / a smaller version of the task] instead. Keep it warm and under 80 words.

[paste the request here]

Use the AI tool your employer has approved. In public tools, remove names, numbers and anything confidential. Read every draft before you send it.

4. Make the request clear

Before you send anything important.

Rewrite this message so the request and the deadline are clear in the first sentence. Remove anything unnecessary. Keep the tone [friendly / neutral].

[paste your draft here]

Use the AI tool your employer has approved. In public tools, remove names, numbers and anything confidential. Read every draft before you send it.

5. A friendly follow-up

For an email that hasn't had an answer.

Write a short, polite follow-up to [name or role] about [topic], first sent on [date]. Ask for [what is needed] by [date]. Don't sound impatient. Keep it under 60 words.

Use the AI tool your employer has approved. In public tools, remove names, numbers and anything confidential. Read every draft before you send it.

6. One-touch triage

For an inbox you've been putting off.

Here are [number] emails. For each one, suggest one action: Do (under 2 minutes), Delegate (to whom), Defer (add to the task list) or Archive. Explain each choice in one line.

7. Catch the promises

At the end of the day, before you log off.

Read these sent messages from today. List every commitment made to someone: who it was for, what was promised and by when. Put the earliest deadlines first.

Write emails faster without sounding like a robot

AI drafts can sound stiff or overly polite. A few habits keep your emails sounding like you.

Ask for short. "Under 80 words" removes most of the filler.
Name the tone. "Warm but direct" or "neutral and brief" works better than no instruction.
Edit the first line. Changing the greeting or opening sentence to your usual style makes the whole message feel more natural.
Check the facts. Dates, names, numbers and promises must be right. The AI can't know what you agreed in a meeting.

For anything involving money, contracts or your manager, open the original email and read it yourself before you reply.

FAQ

Check your employer's AI policy first, and use the tool they've approved for work content. In public tools, remove names, numbers, customer details and anything confidential before you paste.

Which AI tool is best for work emails?

The one your employer has approved. A tool connected to your mailbox, such as Microsoft 365 Copilot in Outlook or Gemini in Gmail, can read messages directly. General assistants like ChatGPT and Claude work just as well with the prompts on this page if you paste the email in.

Do these prompts work in Claude, Gemini and Copilot too?

Yes. They're written in plain language, so you can use them in any AI chat assistant. In a connected tool, leave out the "paste the email here" line and point the tool to the message instead.
