Reading time: about 9 minutes
This is the shortest case in the block and the one that prevents most trouble. It is not about starting to use WhatsApp — you already do — but about writing the message once, properly, and reusing it. And about one rule that summarises the rest: a notice says something is waiting, it does not say what.
Step by step
-
The rule that orders everything else
A WhatsApp message ends up on the lock screen of a phone that might be on a table, in somebody else’s bag or in a relative’s hand. So:
The notice says something is ready. It does not say what.
"Your order is available" works exactly as well as "your diabetes treatment has arrived" and reveals nothing. The medicine name, the condition, the dose and even the type of service are health data, and they do not go in a message.
That single rule settles most cases, and it is the one you write into the prompt.

Ask for the six templates in one go
With the rule inside the prompt, and with the blanks marked so they can be filled without rewriting anything.
Write me WhatsApp message templates for a community pharmacy. MAIN RULE, ABOVE EVERYTHING: The message says something is available. It does NOT say what product it is, which medicine, what it is for, or any health information. Somebody else may read that message on a lock screen. OTHER RULES: - Short. Three lines at most. - Identify the pharmacy at the start: it is called Pharmacy .... - Tone: normal, neither salesy nor robotic. - No emoji except perhaps one. - Replyable, so people can ask. - Blanks marked like this: [NAME], [TIME], [DAY]. GIVE ME ONE TEMPLATE FOR EACH CASE: 1. What they ordered is now available. 2. It has not arrived; when it will. 3. Reminder that it has been waiting for days. 4. Reminder of a service appointment (without naming the service). 5. Change of hours or holiday closure. 6. Confirmation that an order has been taken. And a seventh: the reply for when somebody asks you on WhatsApp something that cannot be answered on WhatsApp.

Run the lock-screen test over them
Read all seven imagining the phone is on a kitchen table and anybody walking past reads it. If the message lets you deduce anything about that person’s health, rewrite it.
The typical slips, and they appear on their own: naming the service ("your pill organiser", "your blood pressure check"), saying "your treatment", or being so specific that it is obvious what it is.
And there is a case that is not about health and matters just as much: group messages. If you send a notice to several numbers at once, use a broadcast list, not a group — in a group everybody sees everybody’s phone number, and that is a real problem that happens every day.
-
Save them where they get used, not in a document
WhatsApp Business has "quick replies": you type
/orderand the whole template appears. That is the difference between templates that get used and templates sitting in a document nobody opens.Five minutes to enter them. And if in your pharmacy whoever is free picks up the phone, this also means everybody sends the same thing — which is half the point of this case.

What the AI does not decide: who you may write to
The wording is the model’s job. This is not. Somebody giving you their number so you can tell them an order arrived does not mean you may message them a promotion or add them to an offers broadcast list. They are different things and the person only said yes to one.
And people must be able to stop receiving them: if somebody replies "stop sending me these", you note it and you comply. It costs less than anything else in this case and it is what separates a notice from spam.
If you are thinking of moving from notices to promotions over WhatsApp, that is different territory — consent, a record of who agreed, and being able to prove it — and you check it with whoever handles your data protection. A chat will not warn you about that: it will write you the promotion.
A full example, and what is wrong with it
The seven templates from step 2, with the main rule stated first. Here are four of the seven.
1. Available: "Hi [NAME], it’s [PHARMACY]. Your order is ready. You can collect it until [TIME]. See you soon!"
2. Not arrived: "Hi [NAME], it’s [PHARMACY]. Your order did not come in today; we expect it on [DAY]. I will let you know as soon as it arrives."
4. Service appointment: "Hi [NAME], it’s [PHARMACY]. Reminder of your blood pressure check tomorrow at [TIME]. Let me know if you cannot make it."
7. Cannot be answered here: "Hi [NAME], this is better looked at in person. Could you come by today before [TIME]?"
And now, what is wrong with that reply:
- Number 4 names the service, and that is health data. "Your blood pressure check" on a lock screen says that person monitors their blood pressure. The prompt explicitly asked for "without naming the service", and it slipped through anyway — because a reminder that does not say what for feels incomplete to the model. "Reminder of your appointment tomorrow at [TIME]" works identically and reveals nothing.
- Numbers 1 and 2 are perfect, and it is worth seeing why. "Your order" does not say what it is. Anybody reading that screen knows the person shops at a pharmacy — which is no secret — and nothing else. That is the rule working: the notice says something is ready, not what, and the message does the job identically.
- Number 7 is the best of the seven and the one nobody asks for. It handles the awkward moment — somebody asking on WhatsApp something that cannot be answered on WhatsApp — without saying no and without explaining. Having it written stops you improvising, which is when you answer more than you should. If you keep only one of the seven, keep this.
- And all of them open with "Hi [NAME], it’s [PHARMACY]", which is right. It looks repetitive and it is not: a message from an unknown number with no identification reads as spam or a scam, especially if it asks you to come somewhere. Identifying yourself first is what makes the message get opened.
One in seven with a real problem, and it is the one most often sent of the four that involve appointments. The fix is three words shorter.
Run the lock-screen test over all seven before saving them as quick replies: the time to fix them is now, because once saved they get sent without rereading — which is exactly what they are saved for.
