The 24-hour reply window

1 min read

Summary

WhatsApp only lets businesses send normal messages within 24 hours of the customer's last message.

This is WhatsApp's rule, not Slot Reply's. It applies to every business.
For 24 hours after the customer's last message you can send anything. The chat header shows the time left.
After that, only an approved message template is delivered. The reply box turns off and says so.
As soon as the customer writes again, the window opens for another 24 hours.

Send a template from a chat

Reach a customer after the 24-hour window has closed with an approved WhatsApp template.

What message templates are

Messages approved by WhatsApp in advance, needed for anything you send more than 24 hours after a customer's last message.
