# LINE

The **LINE element** allows you to send LINE messages to users as part of your Customer Journey. You can choose between using a message preset for advanced formatting or entering simple free-form content.

To configure the LINE element, enter a step name and choose how you want to define the message content:

* **Preset**  
   Select from the LINE message presets you’ve created under **Content > LINE Presets**.

* **Custom content**  
   Enter plain-text content directly into the **Custom content** field.

> **Note:** When using custom content, no additional settings are available. Users will only receive the plain text you enter. To access advanced configuration options, use a preset.
## Use vouchers 

You can personalize LINE messages by including a unique voucher code from a predefined pool. This is ideal for delivering promotions, discounts, or loyalty incentives through one-on-one communication.

To use vouchers in your LINE message:

1. Ensure your LINE message template includes the placeholder ``{{voucher}}``.
2. In the LINE message step, toggle **Vouchers** to ON.
3. Select the appropriate **Voucher Pool** that contains your voucher codes. Make sure the pool is created in advance.
4. (Optional) Use the **Assign Tag** field to apply a tag to users who receive a voucher. This helps with segmentation and reporting.

## Delivery-based flow control (optional)

Use the **Split flow depending on whether this message is delivered or not** toggle to define how the journey should proceed based on delivery status:

* **Enabled**: The journey splits into two paths—one for successful delivery and one for delivery failure.

* **Disabled**: The journey continues along a single path, regardless of delivery outcome.
