Reply on WhatsApp: the 24-hour window

ZZiReach· Checked 6 Nov 2026

When you can type a free-text reply to a WhatsApp customer, and what happens once the window closes.

The reply window

WhatsApp lets a business send a free-text reply for 24 hours after the customer's last message. In the Inbox, an open conversation shows how much of the window is left. A new message from the customer opens it again.

When the window has closed

The reply box says the window is closed, and a free-text reply cannot be sent. Approved follow-up templates still go out as part of Lead follow-up, and the conversation shows a note when one is scheduled.

Sending template messages by hand from the Inbox is not available yet.

If a message could not be delivered

When WhatsApp cannot deliver the last message to a number, sending to that number pauses. It resumes when the customer messages you, or after 30 days.
