How to Get AI to Write Emails That Sound Like You

You ask an AI assistant to draft a quick email to your child’s teacher. What comes back starts with “I hope this message finds you well” and ends with “Please do not hesitate to reach out.” It’s polite and the grammar is fine, but nobody who knows you would believe you wrote it.

The fix is simple. The AI writes in a generic voice because you haven’t shown it your voice. Once you give it a few examples and some clear tone instructions, the drafts start to sound much more like you. Then you spend a minute editing, and the email really is yours.

Why AI emails sound like robots

AI assistants learn to write from a huge amount of text, and later training pushes them to be polite and inoffensive. When you don’t tell them otherwise, they fall back on the safest, most average version of an email. That’s why the same phrases keep showing up: “I wanted to reach out,” “I hope you’re doing well,” “Thank you for your understanding.”

You probably write differently. Maybe you skip the greeting with close colleagues. Maybe you use short sentences, or a dash of humor, or sign off with just your first initial. The AI can’t know any of this unless you show it.

Step 1: Collect a few samples of your writing

Find three to five emails you’ve already sent that sound like you on a good day. Pick a mix if you can:

• A quick, casual one (a note to a coworker about lunch plans)
• A more careful one (asking your landlord to fix the heating)
• One where you said no or delivered news someone didn’t want

Before you paste anything, remove names, addresses, phone numbers, account numbers and anything private. Swap them for placeholders like [NAME] or [COMPANY]. What makes these samples useful is how you write, so the personal details can go.

Step 2: Ask the AI to describe your style

Rather than just saying “write like me,” have the AI study your samples first. This works in ChatGPT, Claude, Gemini, Copilot, or any similar assistant.

Below are a few emails I've written. Please study them and describe my writing style in a short list: sentence length, how formal I am, how I open and close emails, words or phrases I use often, and anything I never do.

Email 1:
[paste email]

Email 2:
[paste email]

Email 3:
[paste email]

Read the list it gives back. Does it match how you see yourself? If it says “uses exclamation points often” and you hate exclamation points, correct it. Keep the final version, because this is your style guide.

Step 3: Write the email using your style guide

Now give the AI the style guide and tell it what you need. The more specific you are about the situation, the better the draft. Use placeholders for names and private details here too, and fill them in yourself afterward.

Here is a description of my writing style:
[paste your style guide]

Write an email in this style.
To: [who it's for and how well you know them]
Purpose: [what you need to say or ask]
Key points: [the facts or details to include]
Tone: [for example: friendly but firm, brief, apologetic, upbeat]
Length: [for example: under 100 words]

Here’s an example. A small bakery owner might fill it in like this: “To: a regular customer I know well. Purpose: let her know we can’t do her custom cake this Saturday, and offer next Saturday instead. Tone: warm and a bit apologetic. Length: short.”

Step 4: Adjust the tone

If the first draft is close but not quite right, don’t start over. Just say what to change. Short follow-ups usually do the job:

Make it shorter and more casual.

Remove "I hope you're well" and any other filler. Start with the main point.

This sounds too stiff. Rewrite it the way I'd say it out loud to a friend.

Keep the same message but make it firmer. I'm asking for the third time.

It also helps to give the AI a list of phrases to avoid. It’s worth keeping a list like this handy:

Never use these phrases: "I hope this email finds you well," "I wanted to reach out," "Please don't hesitate," "Thank you for your understanding," "circle back." Avoid exclamation points unless I use one in my notes.

Step 5: Save your setup so you don’t repeat it

Pasting your style guide every time gets old fast. Most assistants let you save standing instructions or set up a reusable project or custom assistant, though what that’s called and where you find it varies by product and changes over time. Anything you save there is stored by the provider, so keep personal details out of your style guide. If your assistant doesn’t have anything like that, keep your style guide in a note on your computer or phone and paste it at the top of new chats.

Step 6: Always edit before you send

Treat this step as part of the job, not an extra. The AI gives you a first draft. Before you hit send, read it as if you were the person getting it.

Watch out for

Some things AI often gets wrong in emails:

• Made-up details. It may add a date, a price, a promise or a “as we discussed” that never happened. Check every fact against what you actually know.
• Things you didn’t mean to say. An extra “happy to help anytime” can commit you to work you don’t want.
• Leftover robot phrases. Even with good instructions, stock phrases sneak back in. Delete them.
• The wrong level of warmth. A draft can be too friendly for a complaint or too formal for a close coworker.
• Length creep. AI tends to say in five sentences what you’d say in two.

A quick test is to read the email out loud. If any sentence sounds like something you’d never say, rewrite it in your own words. It’s usually quick.

Keep private things private

Emails often contain personal, medical, financial or work information. Before you paste anything into an AI assistant:

• Replace names, addresses, account numbers and health details with placeholders, then fill them back in yourself after.
• Check your employer’s rules before using AI with work emails. Many workplaces have policies about which tools are allowed and what can be shared.
• Check your assistant’s settings to see whether your conversations might be used to improve the product. If there’s an option to turn that off, you can. What’s available depends on the product, your plan and where you live. Turning it off may not stop the company from keeping your chats for a while.

For anything sensitive, like a dispute with a landlord, a note to a doctor’s office or a message about money, you can describe the situation in general terms and ask for a structure or a few phrasing ideas. Then write the real email yourself.

A quick recap

1. Gather three to five emails that sound like you, with private details removed.
2. Ask the AI to describe your style, and fix anything it gets wrong.
3. Give it your style guide plus the purpose, key points, tone and length, using placeholders for private details.
4. Tweak the draft with short follow-up requests.
5. Save your setup so you can reuse it, without personal details in it.
6. Edit every draft before it goes out.

The AI can do the heavy lifting on a first draft. Making it sound like you is your job, and it’s quick once you get used to it.
