The test for any message
Before designing anything, one question:
Would the customer be annoyed if this did not arrive?
If yes, it is a message worth sending. Order dispatched. Appointment tomorrow. Payment received.
If no, think again. That is the definition of a promotional message, and promotional messages on WhatsApp are where businesses damage the channel they just built.
The messages that work are the ones customers would ask for.
1. Order and delivery updates
What it is. Confirmed, dispatched, out for delivery, delivered. With a tracking link.
Why it works. Customers want this. Open rates are high because the content is genuinely useful.
Where it pays. Every “where is my order” enquiry it prevents is support time saved. For a business shipping regularly, this alone can justify the whole project.
Category: utility. Cheaper and less restricted.
Watch for: sending too many stages. Four updates per order is helpful. Nine is irritating. Pick the moments that actually matter to the customer.
2. Appointment reminders
What it is. A reminder the day before, and optionally on the day.
Why it works. No-shows cost money and reminders reduce them measurably.
Where it pays. Clinics, salons, service visits, consultations — anywhere a missed slot is lost revenue.
Make it useful: include the time, the location, and a way to reschedule. A reminder that only says “you have an appointment” wastes the message.
3. Support conversations
What it is. The customer messages you. An agent replies, with their order history in front of them.
Why it works. No service window problem — they started it. And customers prefer messaging to phoning or emailing.
Where it pays. Faster resolution, and agents handling several conversations at once rather than one call at a time.
What makes it work: the agent must see who this is. Their orders, their invoices, their previous conversations. Without that, they are asking the customer to repeat things.
FIGURE 1: THE THREE THAT PAY FASTEST
Order updates
- High value, genuinely wanted, and it removes “where is my order” enquiries.
Appointment reminders
- Reduces no-shows measurably. Include time, place and a way to reschedule.
Support conversations
- Customer-initiated, so no template needed. Agents handle several at once.
4. Payment reminders and links
What it is. An invoice due, with a payment link.
Why it works. Gets seen, and removes the friction between deciding to pay and paying.
Where it pays. Faster collection. For most small businesses that is worth more than the message costs.
Be careful with tone. A reminder is not a chase. Firm and polite, and escalate to a person rather than to a harsher message.
5. Document delivery
What it is. Invoices, receipts, statements, tickets, confirmations.
Why it works. Email attachments get lost. WhatsApp documents do not.
Where it pays. Fewer “can you resend that” requests.
6. Order collection and returns
What it is. Ready for collection, return received, refund processed.
Why it works. These are exactly the moments customers are wondering about.
What does not work
Four things that damage the channel.
Broadcast promotions. Allowed, expensive, and the fastest route to reports and blocks. If you must do promotional messaging, keep it rare and make it genuinely relevant.
Messaging people who did not opt in. Directly harms your quality rating and it is a legal problem in most jurisdictions.
High frequency. More than a couple of messages a week, unless the customer is in an active transaction, reads as intrusive.
Chatbots that will not hand over. A customer stuck in a loop on WhatsApp is more annoyed than one stuck on a website, because it feels personal.
FIGURE 2: MESSAGES THAT BUILD THE CHANNEL AND ONES THAT BURN IT
Build it
- Order dispatched with tracking
- Appointment tomorrow at 3pm
- Your invoice is ready, pay here
- Reply to a question they asked
Burn it
- Weekly promotional broadcast
- Messages to people who never opted in
- Nine updates for one order
- A bot that will not pass to a person
Designing a good message
Five rules.
One purpose per message. Do not combine an order update with a promotion.
Say who you are. Not everyone saves business numbers.
Include what they need to act. An order number. A time. A link.
Keep it short. This is a messaging app, not email.
Make the next step obvious. Track here. Reply to reschedule. Pay here.
The opt-out you must build
Every messaging programme needs a working way to stop.
Accept it in plain language. “Stop”, “unsubscribe”, “no more messages” — people will not use your exact keyword.
Act immediately. Not at the next sync.
Record it. So a different system does not message them next week.
Make it visible. Hiding the opt-out costs more than the unsubscribes save, because people block instead — and blocks hurt your quality rating.
Measuring it
Read rate. Should be high. If it is not, your content is not wanted.
Reply rate. Are people engaging where you want them to?
Support enquiries avoided. Compare “where is my order” volume before and after.
No-show rate, if you send reminders.
Blocks and reports. Watch this closely. Rising means something is wrong, and it precedes losing the channel.
Quality rating. Check it regularly.
FIGURE 3: A SENSIBLE ORDER TO ROLL OUT
Start with order updates
- Highest value, clearly wanted, clearly utility.
Add support conversations
- Customer-initiated, no template needed.
Add reminders or payment links
- Whichever fits your business better.
Consider promotion last, or never
- Rare, relevant, and only to people who opted in for it.
A realistic first project
Weeks 1–3. Business verification, provider chosen, number set up. Mostly waiting.
Week 4. Write and submit order update templates. Expect at least one rejection.
Week 5. Connect to your order system. Test thoroughly with real orders.
Week 6. Go live with order confirmations only. Watch the quality rating.
Week 8. Add dispatch and delivery updates.
Week 10. Open support conversations.
Then stop and run it for a couple of months before adding anything else.
The short version
Send what customers would miss if it stopped. Order updates, reminders, payment links, support replies.
Do not send what they did not ask for. Broadcast promotion is where the channel gets damaged.
Start with order confirmations, measure the reduction in support enquiries, and watch your quality rating from day one.
Fielding “where is my order” all day?
Get in touch. Order updates on WhatsApp usually pay for the whole project in support time saved.
