How to Use AI to Write Emails, Letters and Cover Letters

Writing a tricky email, a formal letter or a cover letter can take far longer than it should. This guide is for anyone who wants to use an AI chatbot such as ChatGPT, Claude, Gemini or Copilot to get a strong first draft quickly, then shape it into something that sounds like them. You will learn what to give the AI, ready-made prompts for common messages, and how to check and personalise every draft before you press send.

What AI Is Good At, and Where It Needs You

AI writing tools are excellent at structure and wording. They can turn rough notes into a clear message, suggest a polite way to say something awkward, adjust tone from casual to formal, and tidy grammar and spelling. They are especially helpful when you are staring at a blank page or are writing in a language you are less confident in.

They are much weaker at the things only you know. An AI does not know your real experience, what happened in a meeting, the history with a particular colleague or what you actually want to happen next. If you do not tell it, it will fill the gaps with plausible-sounding but invented or generic details. Your job is to supply the facts and the judgement; the AI's job is to help with the words.

The Basic Method for Any Message

Whatever you are writing, the same process works. The more specific your input, the less editing you will need afterwards.

1. Jot down your key points first Before opening the AI, write three to five bullet points: who it is to, why you are writing, the main facts and what you want the reader to do.
2. Give the AI the full picture Tell it the type of message, the reader, your relationship with them, the tone you want and how long it should be. Paste in your bullet points.
3. Ask for a draft Let it write a first version. Do not expect perfection; treat it as raw material.
4. Refine with short instructions Ask for changes such as make it warmer, cut it to five sentences or make the request clearer in the first paragraph.
5. Edit it yourself Read the draft aloud, correct any facts, remove phrases you would never say and add personal details.
6. Do a final safety check Confirm names, dates, amounts and attachments, and make sure nothing has been invented.

A sample prompt: Write a short, polite email to my child's school asking whether they can be collected early on Friday 14th for a dental appointment at 2pm. I am writing to the class teacher, whom I have met. Keep it friendly and under 100 words. Do not invent any extra details.

Adding do not invent any extra details is a small habit that prevents a lot of editing later. So is asking for two or three short versions, so you can pick the one closest to how you would naturally write, then refine that one further.
