The practical takeaway
WhatsApp is a channel, not a process. Start with a repeated conversation that ends in an observable outcome: an appointment, a document request, or a status update. Keep the human handover visible. Checked October 18, 2026: each customer message opens or resets a 24-hour service window. Outside it, an approved template is required. Record contact permission and honor opt-outs. Meta’s pricing is based on delivered messages and varies by recipient market and category; service messages in the window have no Meta charge. The provider may still charge for its platform. Estimate Meta and provider costs separately using your intended message mix.
Keep these points in mind.
- Check the 24-hour service window and approved-template requirements before sending reminders.
- Connect conversations to your CRM, scheduling, or support system.
- Design the human handover and record of actions from the start.
