How to Write a Professional Email With AI (Not Like a Bot)
A four-step workflow for drafting emails with ChatGPT and fixing the tone, with before/after templates for follow-ups, complaints and requests.
AI is good at the part of email writing that most people hate: getting a first sentence down. It is bad at the part that matters: sounding like a specific person writing to another specific person about something real. Left unedited, an AI email opens with “I hope this message finds you well”, thanks the recipient for their “continued support”, and asks them to “kindly advise at their earliest convenience”. Recipients notice, and it costs you a little credibility every time.
The fix is a short workflow. Draft with AI, correct the tone, humanize, then check. Twenty minutes for the first few emails, under five once it is habit.
The workflow
Step 1: Draft with a specific prompt
Vague prompts get generic emails. Give the model the facts and the constraint:
Write a 4-sentence follow-up email to a client, Dana, who has not replied to a proposal I sent on 4 September. Friendly but direct. No “hope this finds you well”. End with a specific question.
The more specifics in the prompt (names, dates, what you actually want them to do), the less you have to fix later.
Step 2: Fix the tone
AI defaults to a tone that is slightly too formal and slightly too apologetic for most working relationships, and slightly too breezy for formal ones. Decide what you want (direct, warm, firm, neutral) and adjust. Doing this by hand means reading each sentence and asking “would I say this?”. Doing it with the tone changer means pasting the draft, picking a target tone, and editing the result.
A tone change is not a full rewrite. It should keep every fact and request intact while changing the register.
Step 3: Humanize
Now remove what still sounds generated: filler openers, “I wanted to reach out”, stacked adjectives, the reflexive “please do not hesitate to contact me”. The humanizer does this mechanically; the list of phrases to avoid is the manual version. Then add one thing only you could have written: a reference to the last conversation, a detail about their situation, the specific thing you need.
Step 4: Check
Read it once aloud. Run the grammar checker. Confirm the names, dates and attachments are right. Send.
Three templates, before and after
Each “before” is typical unedited AI output. Each “after” is what the four steps produce.
1. Follow-up on an unanswered email
Before: Subject: Following Up on Our Previous Correspondence
Dear Dana,
I hope this email finds you well. I wanted to reach out to follow up on the proposal I sent over on September 4th regarding the website redesign project. I understand that you are likely very busy, but I would greatly appreciate it if you could take a moment to review the document at your earliest convenience and let me know your thoughts. Please do not hesitate to reach out should you have any questions or require any further information. I look forward to hearing from you soon.
Best regards, Sam
After: Subject: Website proposal — any questions?
Hi Dana,
Checking in on the redesign proposal I sent on 4 September. I know Q4 planning is eating your week.
Two quick things would help me: is the scope roughly right, and is the October start date still realistic on your side? If not, tell me what has changed and I’ll adjust.
Sam
What changed: the subject says what the email is about, the filler opener is gone, there is one specific acknowledgement of Dana’s situation, and the ask is two concrete questions rather than “your thoughts”.
2. Complaint to a supplier
Before: Subject: Concern Regarding Recent Order
Dear Customer Service Team,
I am writing to express my dissatisfaction with a recent order I placed with your company. Unfortunately, the product I received was not in the condition I expected, which has been quite disappointing. I have always valued your company’s commitment to quality, and I trust that this matter will be resolved promptly. I would appreciate it if you could look into this issue and advise me on the next steps. Thank you for your attention to this matter.
Sincerely, Priya Nair
After: Subject: Order #48213 — damaged on arrival, replacement needed
Hello,
Order #48213 (two ceramic planters, delivered 15 September) arrived with one planter cracked through the base. Photos attached.
I’d like a replacement for the damaged planter sent to the same address. If that isn’t possible, please refund the item and the delivery charge for it.
Can you confirm which you’ll do by Friday?
Priya Nair
What changed: the order number, product, date and damage are stated in the first line. The complaint asks for a specific remedy with a fallback and a deadline. Nothing about being “disappointed”; the facts do that work.
3. Request to a manager
Before: Subject: Request for Time Off
Dear Mr. Okafor,
I hope you are doing well. I am writing to formally request time off from work for a period of five days, from October 13th to October 17th, in order to attend to some personal matters. I have ensured that all of my current projects are on track and I will make every effort to ensure a smooth transition of my responsibilities during my absence. I would be grateful if you could kindly consider my request and let me know if this is acceptable. Thank you very much for your understanding.
Kind regards, Tom
After: Subject: Leave request: 13–17 October
Hi James,
I’d like to take 13–17 October as annual leave (5 days).
The Henley report is due on the 10th so it’ll be finished before I go, and Maria has agreed to cover the Tuesday client call. Nothing else is due that week.
Let me know if that works.
Tom
What changed: it uses the manager’s first name (match whatever your workplace does), states the dates once, and replaces “I will make every effort to ensure a smooth transition” with the actual arrangements. That is the sentence a manager wants to read.
Tone cheat sheet
| Situation | Aim for | Avoid |
|---|---|---|
| Follow-up | Light, specific ask | Apologising for following up |
| Complaint | Factual, remedy stated, deadline | Emotional language, threats, vagueness |
| Request | Direct, prepared, easy to say yes to | Over-justifying, “kindly” |
| Declining something | Short, clear no, one reason at most | Long explanations, false openings (“maybe later”) |
| Bad news to a client | Lead with the news, then the plan | Burying it in paragraph three |
| Cold outreach | One line on why them, one ask | Flattery, “I came across your profile” |
Phrases to cut from any AI email
- I hope this email finds you well
- I wanted to reach out / touch base / circle back
- Please do not hesitate to contact me
- At your earliest convenience
- Thank you for your attention to this matter
- I trust this is acceptable
- Kindly (as in “kindly advise”)
- As per my previous email
- I am writing to inform you that
- Please find attached (say “Attached:” or just “Photos attached”)
Three habits that make this work
Give the model the facts, not the feeling. “Write a polite email” produces filler. “Write an email that asks for X by date Y because Z” produces something usable.
Edit for one reader. Every email goes to a person. Add the one detail that proves you know who they are and what they are dealing with. A model cannot do this; it is the whole value you add.
Shorter is safer. AI drafts run long because length looks like effort. In email, it looks like the writer did not know what they wanted. Cut to the facts and the ask, then decide whether one warm sentence belongs.
FAQ
Is it unprofessional to use AI to write emails?
No, provided the result is accurate, in your voice, and you take responsibility for it. Most people already use spell-checkers and templates. The problem is not the tool; it is sending an obviously generated email that signals you did not care enough to read it. The workflow above fixes that.
How do I change the tone of an AI email quickly?
Use the tone changer: paste the draft, pick the register (formal, friendly, direct, and so on), and edit the result. Then check the facts survived. For a manual pass, replace hedges (“I would greatly appreciate it if you could possibly”) with direct asks (“Could you…”) and delete any sentence that only exists to be polite.
Should I tell recipients I used AI?
For routine business email, no one expects a disclosure any more than for using a spell-checker. For anything where authorship matters (a reference letter, a personal apology, a message representing your organisation’s official position), write it yourself or edit until every sentence is one you would defend as your own.
