The **WhatsApp Business 24-hour window rule** means that once a customer stops replying for 24 hours, you can no longer send them a free form message. The window closes, and the only way to reach that person again is an approved template. If they reply to it, the window reopens and normal conversation resumes.

## Why the window exists at all

**Meta** built the rule to stop business accounts from broadcasting into people's private messaging. Conversation has to be invited by the customer, not pushed by the company.

For support and sales teams, that turns one operational question into a daily reality: is this conversation still open, and if not, how do I restart it?

What teams get wrong about the window:

- Assuming a message failed for technical reasons when the window simply closed
- Discovering the closure only after the send fails
- Having no template ready for the process at hand
- Sending a template when a plain message would have worked
- Losing track of which conversations are still active

## Open window versus closed window

| Situation                                          | What you can send           | Cost implication                       |
| -------------------------------------------------- | --------------------------- | -------------------------------------- |
| Customer replied in the last 24 hours              | Any free form message       | No additional Meta charge for replying |
| More than 24 hours since the last customer message | An approved template only   | Template sends are charged by Meta     |
| Customer answers the template                      | Free form messages again    | Window reopens                         |
| Customer ignores the template                      | Template only, still closed | Each attempt is a template send        |

*Charging follows Meta's own pricing table, which applies regardless of the platform you use.*

## How Jestor handles the window in practice

1. **See the status before typing:** the interface indicates when the window is closed for that conversation.
2. **Send a template straight from the message box** without leaving the conversation.
3. **Pick from the templates available for that process**, since templates can be scoped per flow.
4. **Check the delivery indicators** for sent, delivered and read, plus an error warning if something fails.
5. **Set a background color for the chat** so **WhatsApp** conversations are visually distinct from internal ones.
6. **Let the team work in parallel**, with replies from multiple people updating without a page refresh.

## Why this matters for operations teams

- **No silent failures:** you know the window is closed before attempting the send
- **Templates scoped per process:** support sees support templates, sales sees sales templates
- **Read and delivery status visible:** no guessing whether the customer saw it
- **Number displayed on screen:** clear which of your numbers is in the conversation

## Frequently Asked Questions

### Can I send any message after 24 hours of silence?

No. Only an approved template, until the customer replies and reopens the window. See [jestor.com](https://www.jestor.com/?ref=blog.jestor.com).

### Does replying to a customer cost extra?

Receiving and replying manually inside the window has no extra Meta charge. Template sends are billed by Meta.

### Who approves the templates?

Meta reviews and approves each template before it becomes active.
