# Campaigns

The **Campaigns** module at RUM Work allows you to send manual or scheduled messages or messages to single or multiple contacts. For this, you can use a simple message or a [pre-approved message template](https://docs.rumwork.io/messaging-channels/whatsapp-integration/whatsapp-message-templates) based on the selected [Channel](https://docs.rumwork.io/messaging-channels/channels-overview). 

To access the Campaigns, head over to the left sidebar and select **Campaigns**.

For WhatsApp Channels like [360dialog](https://docs.rumwork.io/messaging-channels/whatsapp-integration/360dialog), [Emma](https://docs.rumwork.io/messaging-channels/whatsapp-integration/emma), and [Cloud API](https://docs.rumwork.io/messaging-channels/whatsapp-integration/cloud-api), you can send a simple message or List/Button/Options/Product Messages only when it's within the 24-Hour Window of the last message received from the users or customers.

WhatsApp Business Platform has a Customer Service Window (24-hour) in which businesses can send both simple messages and [pre-approved templates](https://docs.rumwork.io/messaging-channels/whatsapp-integration/whatsapp-message-templates). Outside the customer service window, the business would require a message template.

The WhatsApp Business Platform works around two different categories of conversation:

1. **User-initiated** - When the user or customer sends the message to the business. The business can respond to the message with a simple message or message template within 24 hours. Once the window has expired, the business can only respond with a message template which will be counted as a **Business-initiated** conversation.
2. **Business-initiated** - When the business reaches out to the customer outside the 24-hour customer service window, its falls under the Business-initiated conversation. For a business-initiated conversation, a message template is required.

{% hint style="warning" %}
To send a campaign message under the Business-initiated conversation type, your business platform must obtain user consent (opt-in) to receive notifications, order updates, event updates, etc. The opt-in could be a simple message or subscription from your website showing the user's consent to receive business-initiated messages from your platform.
