The simple email formula
Almost every email — work, customer, personal — fits the same shape. Tell AI to use this shape and your drafts go from awkward to professional in one prompt.
- One-line warm opener — say hi, refer to context, set tone.
- The point — what you're writing about, in one or two sentences.
- What you need (or what's next) — a clear ask or update.
- A friendly close — short, human, no corporate jargon.
The 3 prompts you'll actually use
Save these three in your notes app. They cover 95% of emails most people send.
- Draft a fresh email — "Write a short, friendly email to [recipient] about [topic]. Use a warm but professional tone."
- Reply to a tricky one — "Help me reply to this email kindly but clearly: [paste]. Keep it under 100 words."
- Polish what I wrote — "Rewrite this in clear, friendly English. Don't change the meaning: [paste]."
An example that shows the whole flow
Here's a real situation most freelancers and small business owners face — replying to a client who's late paying without sounding accusatory.
Prompt: "Help me write a polite follow-up email to a client whose invoice is 14 days overdue. I want to keep the relationship warm but be clear that I need payment. Under 80 words, no exclamation marks." Draft: "Hi [Name], hope you're doing well. Just a gentle nudge — invoice #102 from May 1st is still outstanding. I'd really appreciate it if you could process it this week. Let me know if there's anything I can do to make it easier. Thanks so much, [your name]."
How to keep your voice on top
AI drafts can sound a little generic if you ship them as-is. Two small habits keep every email feeling like you.
- Replace AI's opening line with the way you actually start emails (e.g., "Hey [Name]," or "Hi [Name] — quick one").
- Replace the closer ("Best regards" → whatever you actually use, like "Cheers," "Thanks," "Talk soon").
- Add one tiny detail only you would write — a reference to your last chat, a small joke, an inside note.
What to never let AI write for you
There are a few email types where AI's help can quietly cost you. Write these yourself, even if they're rougher.
- Apologies — these need your real voice and ownership.
- Difficult feedback — AI tends to over-soften and the message gets lost.
- Emotional updates to friends or family.
- Anything where your specific story is the point.
Build a personal template library
Every time AI writes an email you love, save it as a template. Within a few weeks you'll have a personal library — invoice follow-ups, intro emails, decline-politely emails, customer apology emails — that turn future emails into a 30-second copy-edit job.
FAQ
What's the fastest AI email prompt?
"Write a friendly, professional email to [person] about [topic] in under 80 words." That single line covers most situations.
Should I tell people I used AI to write the email?
Generally no — the same way you wouldn't say "I used spellcheck." The thinking is still yours.
How do I stop emails from sounding robotic?
Replace the opening and closing line with the words you actually use. That alone changes 70% of the tone.
Can AI write emails in a different language?
Yes. Tell it the language and the level of formality. Claude tends to handle non-English emails more naturally than ChatGPT.
Will AI store my emails forever?
Most consumer AI tools keep chat history but let you delete or turn it off. Check your settings if you're handling sensitive content.
