Service reminder prompt
A copy-and-paste prompt for ChatGPT, Claude or Gemini that gets a professional service reminder on the first try, plus the cheapest model that does it well.
What most people type
email for our auto repair shop reminding customers their state inspection is due
It works, but the AI has to guess your shop name, due date or window and how to book, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.
The better prompt
Write a short reminder email from our auto repair shop to customers whose state inspection is due. Details to use: - Shop name: [shop name] - Inspection due date or window: [due date or window] - How to book: [phone, online link or walk-in hours] - Offer or incentive, if any (optional): [offer] - Regulations or fees: [state inspection requirements]. Don't invent legal requirements, fees, deadlines or penalties. Include: - 3 subject line options, each with preview text - A friendly, professional body that fits on one screen, with a greeting using [customer first name] and a line on [vehicle, if known] - One clear call to action: booking the inspection - A signature with [shop name, address, phone, hours]
Replace the [brackets] with your details before you send it: shop name, due date or window, phone, online link or walk-in hours, offer, state inspection requirements, customer first name, vehicle, if known, shop name, address, phone, hours.
Why this version works
- Added direct task and customer context. Makes the reminder's purpose and audience explicit.
- Added placeholders for shop, date, booking. A real reminder needs these facts; none were given.
- Requested subject lines, preview text, one CTA. Standard email structure with a single clear action.
- Barred invented legal rules or fees. State requirements vary and can't be verified.
What a professional service reminder prompt covers
- Booking call to action
- Placeholders for name, vehicle and due date
- Short
