How to Write the Best Reminder Messages for Business (WhatsApp and Email)

Reminder messages cut no-shows, bring people back to abandoned carts, and keep appointments and deadlines on track. When you send them on WhatsApp (and optionally email), you reach customers where they already are—so open rates stay high and support load drops. The WhatsApp Business API lets you send approved templates for reminders (appointments, orders, payments) so every message is both effective and compliant.
This guide gives you reminder message examples and best practices for WhatsApp and email: what to say, when to send, and how to stay within opt-in and template rules. You will find links to Spoki features, customer support, and use-cases.
Why Reminder Messages Work (WhatsApp vs Email)
WhatsApp typically has much higher open and read rates than email. For reminders—appointments, delivery slots, payment due—sending on WhatsApp (or WhatsApp + email) means:
- Visibility: The reminder appears in the same app many people use daily.
- Quick action: Customers can confirm, reschedule, or ask a question in the same thread.
- Fewer no-shows: Timely reminders (e.g. 24 hours before an appointment) significantly reduce no-shows.
- Less “Where is my order?”: Order and delivery reminders cut repeat support questions.
Email still works for longer, detailed reminders (e.g. full itinerary, policy summary) or when the contact prefers email. For first touch on WhatsApp, you must use an approved template; after the customer replies, you have a 24-hour session for free-form follow-up. A reminder that is too early (e.g. a week before an appointment) is often forgotten; one that is too late (e.g. the same morning for an early slot) gives little time to reschedule. Timing is therefore as important as the copy. For setup and templates, see landing-registration and contact.
Reminder Message Examples (WhatsApp Templates)
Below are example structures you can turn into approved templates. Use variables (e.g. {{1}} for name, {{2}} for date/time) so each message feels personal.
Appointment reminder (e.g. clinic, salon, consultant)
Idea: Confirm the appointment and offer a simple way to reschedule or cancel.
Example: “Hi {{1}}, this is a reminder of your appointment on {{2}} at {{3}}. Reply CONFIRM to confirm, or RESCHEDULE to change. Need to cancel? Reply CANCEL.”
When to send: 24–48 hours before the appointment. For booking and automation flows, check Spoki features and book.
Order or delivery reminder
Idea: Tell the customer when to expect delivery or that action is needed (e.g. payment, address confirmation).
Example: “Hi {{1}}, your order #{{2}} is scheduled for delivery on {{3}}. Track here: [link]. Reply if you need to change the date or address.”
When to send: 1 day before the delivery window, or when the order is dispatched. For ecommerce and solutions, see the link.
Payment or deadline reminder
Idea: Polite nudge for an overdue or upcoming payment or deadline.
Example: “Hi {{1}}, a friendly reminder: your payment of {{2}} is due on {{3}}. Pay here: [link]. Questions? Reply to this message.”
When to send: A few days before the due date, or (for overdue) with a clear but respectful tone. For pricing and roi-calculator, use the links.
Abandoned cart or follow-up (with opt-in)
Idea: Bring the customer back to an incomplete action—only if they have opted in to marketing or transactional messages.
Example: “Hi {{1}}, you left items in your cart. Complete your order here: [link]. Reply STOP to opt out of these reminders.”
When to send: Within a few hours of abandonment; avoid sending too many. Always respect opt-out. For customer-support and FAQ, see the pages.
Checklist for any reminder:
- State clearly what is being reminded (appointment, order, payment).
- Give one simple action (confirm, reschedule, pay, track).
- Include a way to opt out or change (reply CANCEL, link to preferences).
- Use an approved template for the first WhatsApp message outside the session.
Best Practices: Timing, Tone, and Compliance
- Timing: Send appointment reminders 24–48 hours before. Order/delivery reminders 1 day before or when shipped. Payment reminders a few days before due (and optionally one polite follow-up if overdue).
- Tone: Keep it short, clear, and respectful. Avoid sounding aggressive or guilty; a simple “friendly reminder” works well.
- One main action: One link or one instruction (confirm, reschedule, pay). Too many options dilute the message.
- Compliance: Only send to contacts who have opted in. For WhatsApp, use approved templates for the first message in each 24-hour window. Offer opt-out (e.g. “Reply STOP”) and process it promptly. Avoid sending the same reminder twice in a short window (e.g. two appointment reminders in one day); one well-timed message is better than several. For artificial-intelligence and chatbot options that can handle “reschedule” or “cancel” in the same thread, see the Spoki page.
Combining WhatsApp and Email Reminders
Many businesses use WhatsApp for the primary reminder (short, high open rate) and email for a backup or for more detail (e.g. full booking details, policy link). Example flow: WhatsApp template 24 hours before: “Reminder: your appointment tomorrow at 10 a.m. Reply CONFIRM or RESCHEDULE.” Email same day or earlier: same message plus link to booking page and customer-support link. That way you cover both channels without duplicating the same long text in WhatsApp. For use-cases and solutions, use the links.
Conclusion
Reminder messages on WhatsApp (and email) reduce no-shows, keep orders and payments on track, and cut support load. Write them short and clear, send them at the right time, and use approved templates and opt-in so every reminder is compliant. With the WhatsApp Business API and a platform like Spoki you can automate appointment, order, and payment reminders and still keep a human touch when the customer replies. Start with one reminder type (e.g. appointments), measure open and response rates, then add order or payment reminders and tune timing and copy based on results. You can also A/B test send times or subject lines (for email) to see what works best for your audience.
