Quick answer
How do I use AI to write customer emails?
AI is good at layout and tone. It shouldn't decide what you promise, charge, admit to or have to do by law.
The jargon
The words you'll come across, in plain English.
- AI: artificial intelligence: computer tools that can write, answer questions or make pictures from what you type.
- Prompt: what you type to tell an AI tool what you want.
- Placeholder: a stand in like [customer] instead of a real name, while you draft.
- Draft: a first version you check and change before sending.
What to give it
What should I give the AI?
- Who it's for (a customer, not their name)
- What the message is for
- The confirmed job facts
- Dates and amounts that must stay exact
- What you want them to do next
- The tone, and how long
- Anything it mustn't add
Examples
What does a good request look like?
Ask like this
Write a calm 120 word update about a delay. Facts: the part arrives Friday; earliest return Monday; price unchanged. Don't blame the supplier or promise a finish date.
Not like this
Tell the angry customer we'll sort everything.
- Appointment: Turn these confirmed details into a 70 word reminder. Don't change the date or arrival time.
- Delay: Write a calm update from these facts. Don't blame anyone or promise a date I haven't confirmed.
- Complaint: Sort these notes into facts, questions and possible next steps. Don't write the reply or admit fault.
If it fills a gap with something that sounds right but isn't, take it out and fix your request.
How careful to be
How careful do I need to be?
A reminder can be drafted from fixed facts. A delay needs you to OK the new timing. A complaint can affect your liability and reputation, so at most let AI sort your notes, then write the reply yourself, carefully.
- Check every date, amount and who it's going to
- Take out any made up cause or diagnosis
- Don't let it add refunds, guarantees or apologies that admit fault
- Keep private details away from anyone who doesn't need them
- Read it out loud: does it sound like you?
Only let anything send automatically once it's been tested, checked and has an off switch.
Final check
What should I check before sending?
- Every name and date is right
- No made up diagnosis or cause
- No refund, guarantee or admission you didn't agree
- Price and VAT match your records
- Right attachments, right person
- Polite, and sounds like a person
Privacy
What about customers' details?
Swap names, addresses and job numbers for placeholders like [customer] while drafting. Never include passwords, payment details or access codes.

FAQs
Frequently asked questions.
Should I tell customers AI helped?
There's no single rule, but never mislead them about who inspected the work or made a professional judgement.
Can AI reply to complaints for me?
No. Complaints can affect your liability and reputation; reply yourself.
Can it translate messages?
It can help, but get anything about the job, price, safety or terms checked by someone who speaks the language.
Can I save my requests to reuse?
Yes. Keep the gaps obvious, and always check the facts at the end.
Can AI make an email legally watertight?
No. Use your proper terms, and get professional advice for anything legal that matters.
Should I keep the AI draft?
Keep the message you actually sent, in your normal records.
