How to Get AI Email Replies That Actually Sound Like You

You've probably seen it: an AI-written email that is technically fine and obviously not written by a person. Too many adjectives, an oddly formal opening, "I hope this email finds you well", and a closing paragraph nobody needed.

When customers, colleagues or clients know you, a reply that doesn't sound like you can feel off, even if it says the right things. Here's what makes your style yours, and how to get AI drafts that match it.

What makes up your email style

Your style is more than "formal" or "casual". It's a set of small, consistent habits:

• Greeting: "Hi Anna," vs "Hello Anna," vs "Dear Ms Weber,".
• Opening line: straight to the point, or a short friendly line first?
• Length: three lines or three paragraphs?
• Sentence rhythm: short and punchy, or longer and explanatory?
• Vocabulary: "Sure!" vs "Of course." vs "Happy to."
• Formatting: bullet points, or never?
• Sign-off: "Best," "Cheers," "Kind regards," and with or without your first name.
• Language and form of address: in German, for example, du or Sie.

People recognise these patterns instantly, even if they couldn't list them.

Why generic AI replies miss the mark

General AI tools are trained to be helpful to everyone, so their default voice is polite, complete and a little bland. Without examples of how you write, they guess. And they guess "average".

There's a second problem: many people have more than one style. Your support inbox, your freelance address and your personal email probably all sound different. One generic voice can't cover them all.

Three ways to get closer to your voice

1. Describe your style in a prompt. Write a short style guide, such as "short sentences, no exclamation marks, sign off with 'Best, Tom'", and paste it into your AI tool every time. It works somewhat, but it's tedious, and descriptions miss a lot.

2. Give examples. Paste two or three of your real emails as examples. Better, but you have to repeat it, and you have to pick good examples each time.

3. Use a tool that learns from your sent mail. The most reliable approach is a tool that looks at emails you've actually sent and keeps a style profile for each account, so you don't have to explain yourself every time.

How LittleDraft learns your style

LittleDraft works alongside Apple Mail and uses approach 3:

• You choose which sent emails it learns from. Your best, most typical replies, not every email you ever wrote.
• A separate style per account. Your support inbox can be warm and structured, and your personal account short and casual.
• Tone and length controls let you nudge a single reply without changing your style.
• You give the direction, it writes the reply. A few words like "decline politely, suggest next month" become a complete email that sounds like you.
• You stay in control. Every reply is a draft you review and send yourself from Apple Mail.

If privacy matters to you, LittleDraft Pro can write replies with Apple's on-device model on compatible Macs, so your conversation, instructions and style stay on your Mac for AI processing. Private drafting gives your instructions priority, keeps the conversation's language, and checks drafts before they're inserted. In English and German, it catches problems like wrong-language output or missing order numbers.

A quick test for any AI draft

Before you send, read the draft and ask:

1. Would I actually write that first sentence?
2. Is it the length I'd normally write?
3. Did it keep the details: names, numbers, dates?
4. Is the sign-off mine?

If the answer is yes four times, you just saved yourself the typing.
