Let AI draft the appointment reminder. You check every fact, then you send it. A plain guide for trade owners.
A no-show takes a slot you cannot sell twice. The customer waited, the drive is gone, and the next job starts late. For a trade owner, an appointment reminder is the short message that keeps the slot honest: when you will arrive, where you will be, and what the customer should do before you get there.
AI is useful at wording and careless with your book. It will smooth a sentence and invent a price, a diagnosis, or a gate code in the same breath. The method is a split. Let AI draft the appointment reminder. You check it against the work order. You send it.
Ethical AI teaches that split to owners who still run the day from a truck and a phone. The model writes a draft. The send stays with a person.
What you are actually sending
The reminder confirms a visit already on the book. It is not a new offer and not a second quote.
Put four things in the message, in this order:
1. Who is writing: your name and the shop name the customer already knows. 2. The visit: weekday, calendar date, and arrival window. 3. The place, written as it sits on the work order, plus one prep step. A clear path to the unit. A car moved. Someone home if you may shut water or power off. 4. One reply path if that window no longer works.
Then stop. A discount or a review request changes the question, and you still need the time confirmed before the truck rolls. How to ask for reviews is a later note, sent after the work. Point it at your Google Business Profile only when that listing shows the phone and hours you keep.
Write the fact note before you open a model
Eight lines, copied from this job, are enough. Do not write them from habit.
- First name, spelled as the customer gave it - The job in their words, not your internal code - Weekday, date, and window, with morning or afternoon written out - Service address, and any unit or gate note you are willing to text - Who from the crew is going, if you promised a name - The one prep step - The number they should use if plans change - The business phone and hours as they stand on your Google Business Profile and on your other small business listings
If a line is empty, it stays empty. Leave a visible blank such as `[window]` or `[prep step]`, and fill it from the work order yourself. Do not ask the model to complete a blank.
Do not let the draft invent a price, a diagnosis you have not already told the customer, or a gate code that is not on the work order. If you would not say it at the door, it does not go in the text.
Run the draft in one order
Paste the fact note. Ask for one text and one short email, same facts, no slogan, and a list of anything the model had to assume. Each stop below has one job. You still compare every number to the note.
**Claude** writes the first draft. You want calm, plain language and that assumption list. If the list is not empty, fix the note and start over. A smooth sentence is not a reason to keep a guessed fact.
**GPT** shortens what Claude wrote. Hand it the fact note again. Tell it to remove hype, extra services, and any sentence that is not this visit. If a time, a date, or an address changes by one character, the draft fails. Check the characters yourself.
**Grok** makes the short version sound like a person about to drive, not a brochure. Short sentences. Readable on a phone in a driveway. The facts stay identical. If the voice gets cute, send that line back.
**Gemini** reads for confusion. Ask it to mark a double time, a bare "tomorrow" with no date, a street with no city, or two addresses that do not match. You repair what it marks. You do not accept a new paragraph you did not ask for.
**Perplexity** is only for a public detail you choose to check, such as the hours or the address on your Google Business Profile. If that summary and your listing disagree, believe the listing you control, then fix the other small business listings that still show an old phone or old hours. The reminder and the listings have to name the same shop.
Don't have Claude? No problem. Start with the model you can open. Keep the fact note and the human check. A missing login does not cancel the reminder.
Don't have GPT? No problem. Ask the next model to shorten the draft. Cutting extra claims matters more than which name does the cutting.
Don't have Grok, Gemini, or Perplexity? No problem. Skip the one you cannot open. Do not skip the read against the work order. You are the person who sends the message.
A drill, not a customer
Nothing below is from a real job. The blanks are the point. Fill them from a work order when you do this for a real visit.
Fact note for the drill:
- Name: [First name] - Job in their words: no hot water, check the water heater - When: Thursday, [month and day], between 10:00 and 12:00 - Where: [service address]; side gate; the code stays on the work order and out of the text - Crew: you - Prep: clear a path to the heater, and be home if the water has to be shut off - Reply: text this same number - Listing phone: the main shop number already on your Google Business Profile
A draft to throw away:
> Hi [First name]! Great news — we can replace the water heater Thursday around 10, and if you leave a review the same day we will take money off the bill. See you soon!
That draft fails the note. "Check" became "replace." The window lost its end time. A discount appeared that nobody wrote down. A review ask got mixed into a confirmation. How to ask for reviews waits until the visit is done.
A draft you can send after you fill every blank and read it once:
> [First name], this is [your name] at [shop name]. We are scheduled Thursday, [month and day], between 10:00 and 12:00, at [service address], to check the water heater. Please leave a clear path to the unit and plan to be home in case we shut the water off. The side gate is fine. Text this number if that window no longer works.
Read it out loud. If the address in the text and the address on your small business listings differ, fix one before you send. Use your real shop name. Keep the shape: who, when, where, one prep step, one way to change the window.
What to check, and what to leave out
Hold the draft beside the fact note.
- The first name matches the work order. - The weekday, the date, and the window are all present, and they agree. - The address matches this job, and the callback number matches your Google Business Profile and your other small business listings. - The prep step belongs to this job, not to the previous text you copied. - There is no price, no discount, and no diagnosis you have not already said. - There is no second customer, no second address, and no sentence from a different job. - There is no review link. The word "tomorrow" is either gone or paired with a calendar date. - The whole message fits on one phone screen.
Leave out crew nicknames, unpaid balances, and gate codes. If you do text a code, type it from the work order yourself. Leave out a promise to arrive on the minute. A window is the promise you can keep.
Send the text yourself, from the number the customer already has. If you also send the email, send the same facts. After it goes out, leave it alone.
The note that goes out after the work
When the job is finished, send a second message if you would ask this person for a review in person. Name the work, thank them, and point to your Google Business Profile only if that phone matches the one you text from. Do not tie the review to the invoice, and do not send it while a complaint is still open.
The next one on the book
Take the first visit already written for tomorrow. Fill the eight-line note from that work order. Run it through the models you actually have. Read the checklist with the draft in your hand. Send one reminder yourself.
