The **WhatsApp 24-hour window** is the period after a customer's message during which you can reply freely. Outside it, outbound contact requires an approved template.

## Why this shapes your process

It is a constraint on timing, not on content.

- A reply written the next morning may need a template
- Follow-up sequences cannot be composed freely
- Delays have a cost beyond customer patience
- Proactive contact always requires preparation

## How to design around it

| Situation                   | Approach                                         |
| --------------------------- | ------------------------------------------------ |
| **Reply within the window** | Free-form; speed keeps the window open           |
| **Reply after it closes**   | An approved template reopens contact             |
| **Proactive notification**  | Always a template                                |
| **Long-running cases**      | Template-based status updates keep contact alive |

## How to manage it in Jestor

1. Prepare and manage approved templates inside **Jestor** before you need them.
2. Use **SLA** tracking so slow replies are visible while the window is still open.
3. Use the reply indicator to see which conversations are waiting on your side.
4. Configure template-based status updates for cases that will run past a day.
5. Let an **AI** agent handle routine messages promptly, which keeps windows open.

## Why choose Jestor for compliant messaging?

**Jestor** manages approved templates inside the platform, so sending one outside the window is a normal step rather than a separate process in another tool.

Because response time is measured per phase, the operational cost of a slow reply — needing a template rather than a free message — becomes visible rather than abstract.
