10 fill-in AI prompts for writing customer emails (and how to adapt them)

Posted on Oct 20 • Originally published at ashishexcelnotes.hashnode.dev

Most customer emails are the same dozen situations again and again: late payments, delays, complaints, refunds. AI chat tools can draft them quickly, but only if you give them the facts. A good habit is a fill-in-the-blank prompt: a fixed sentence with [brackets] for the details that change. Here are ten, plus how to adapt them.

Write a polite reminder to [client name] that invoice [number] for [amount] [currency] was due on [date]. Include payment details: [details]. Keep it under 100 words.

Write a firm but professional reminder for invoice [number], now [days] days overdue. Mention [late fee policy, if any] and ask the client to confirm a payment date.

Write an apology to [customer name] whose order [number] is delayed by [days] because [reason]. Give the new date [date] and offer [solution].

Reply to this complaint: [paste it]. Acknowledge the problem, apologise for [specific issue], and explain what we'll do: [action] by [date]. Don't argue.

Write an email confirming a refund of [amount] [currency] for order [number], processed on [date], arriving in [time] via [method].

Write a short follow-up to [client] about the quote for [service] sent on [date]. Ask if they have questions and mention [availability or deadline].

Write an email telling [client] that [request] is outside the agreed scope. It would cost [amount] [currency] or take [time]. Offer two options.

Tell [customer] that [product] is out of stock until [date]. Offer three choices: wait, switch to [alternative], or get a refund.

Write a polite email declining [request] from [customer] because [reason]. Suggest [alternative].

Ask [customer] for feedback on [product/service] with three short questions: [q1], [q2], [q3]. Under 80 words.

Put the facts in the brackets, not in your head. The AI tool only knows what you type. Amounts, dates and policies have to go in the prompt. Otherwise it will invent plausible-sounding ones, and you'll be the one sending them.

Add a tone line. Add something like "Tone: warm, short, no exclamation marks" or "Tone: formal, British English". You can also paste two emails you've written before and add "match this voice".

Set a length. "Under 100 words" gives you an email people actually read. Without a limit, drafts tend to run long.

Ask for options, then choose. End the prompt with "Give me 3 versions: very short, standard, very polite." It's faster to pick one than to ask for rewrites.

Keep the facts the same in every follow-up. If a reminder goes out three times, the amount, invoice number and due date should never change. Keep them in one place, like your invoice sheet, and paste them in each time.

Read it before you send it. Check every number and date against your records. Remove any promise you can't keep, like a refund window or a delivery date. You're responsible for what goes out, not the tool.

Every one of these prompts has the same shape:

[Action] + [who it's for] + [the facts in brackets] + [what to include] + [limit or tone]

Whenever you write the same kind of email for the third time, turn it into a prompt like this. Over a month you'll build a small library that covers most of your inbox.

I drafted this article with AI tools and edited it before publishing. The prompts are a fill-in-the-blank format, so results depend on the details you add and the tool you use.
