To write professional emails with AI that do not sound robotic, give the tool the full context (who the person is, your relationship, what happened and what you want), ask for a short draft in plain language, and then edit it: cut the stock openers, add one personal detail, and make the request and deadline crystal clear. Keep most emails under 150 words, use a subject line that says what the email is about, and never send an AI draft without reading it as if you were the recipient.
- AI drafts fast. You still decide the tone and the facts.
- One email, one purpose, one clear ask.
- Delete “I hope this email finds you well” and other filler.
- Use templates for routine emails and personalise the first line.
- Smooth stiff wording with the free AI Text Humanizer.
The follow-up that never got a reply
A freelance developer finishes a project for a client abroad. The invoice is two weeks overdue. He asks an AI tool to “write a polite payment reminder” and sends what it gives him: four paragraphs about valuing the partnership, hoping the client is doing well, and kindly requesting that they “look into the matter at their earliest convenience”.
No reply. A week later he writes it himself in three lines: the invoice number, the amount, the original due date, a link to pay, and “Could you confirm when this will be paid?” He gets an answer the same day.
Busy people respond to emails they can understand in ten seconds. AI can help you get there, but only if you steer it.
What to tell the AI before it writes
| Context | Example |
|---|---|
| Who is the recipient? | A client I have worked with for 6 months, friendly but busy |
| What is the situation? | Invoice INV-204 for $450 was due on 10 October |
| What do you want? | Payment, or a date when it will be paid |
| Tone | Friendly, direct, not apologetic |
| Length and format | Under 80 words, subject line included |

Saying no politely
Subject: Re: Logo redesign request
Hi Nadia,
Thank you for thinking of me. I am fully booked until December, so I cannot take this on properly right now. If the timeline is flexible, I would be glad to start in the first week of December.
Best,
Tanvir
Lines to delete from AI drafts
- “I hope this email finds you well.”
- “I am writing to inform you that…”
- “Please do not hesitate to reach out.”
- “At your earliest convenience.” (give a date instead)
- “Thank you for your time and consideration” on every single email.
Not every polite phrase is bad. But when every email contains all of them, readers stop reading. More examples in our list of AI phrases to avoid.
A quick editing checklist
- Subject lineDoes it say exactly what the email is about?
- First lineDoes it get to the point or add a genuine personal touch?
- One askIs the request clear, with a date if needed?
- LengthCan you cut a third without losing meaning?
- FactsAre names, amounts, dates and links correct?
- ToneRead it as the recipient. Would you be happy to receive it?
Writing emails in English as a second language
AI is very helpful when English is not your first language. Write what you want to say in simple English (or even Bangla), ask AI to turn it into a clear professional email, then compare the two versions to learn new phrases. If you want to practise speaking for client calls too, try the free Lumi AI English Robot.

What should I avoid in professional emails?
