Use WhatsApp Business and set up quick replies or away messages for limited automation
Use a third-party scheduling app that supports WhatsApp message scheduling
On Android, use automation tools like Tasker or SKEDit to schedule messages
On iPhone, use the Shortcuts app to create a time-based automation and send a WhatsApp message
Open the scheduling tool, select the contact or group, and type your message
Choose the date and time you want the message sent
Grant the required permissions for contacts, notifications, and accessibility if needed
Confirm and save the scheduled message
Check the app later to make sure the message is still queued
Manually send the message if your chosen tool only reminds you instead of sending automatically
