# Line: Send messages

After you’ve set up LINE, you can send messages to your audience as a part of campaigns or broadcasts.

## Send a LINE message[](#send-a-line-message)

As a part of your campaign or broadcast workflow:

1.  Drag **LINE** into your workflow.

2.  Click the message and click **Add Content**.
3.  If you store your audience’s LINE ID in an attribute other than `line_id`, set the correct attribute in the **To** field.
4.  Add text and image content to your message.
5.  Click **Save Changes**.

## What kinds of messages can I send?[](#what-kinds-of-messages-can-i-send)

While LINE supports a variety of message types, we support [basic text](https://developers.line.biz/en/docs/messaging-api/message-types/#text-messages) and [image messages](https://developers.line.biz/en/docs/messaging-api/message-types/#image-messages).

You can send text and an image in the same message, but your text and image appear to the user as separate messages. We don’t charge you by the message, so this doesn’t affect your usage or bill!

## How do you set the LINE ID?[](#how-do-you-set-the-line-id)

By default, the LINE ID—the way you identify your LINE audience—is the `line_id` attribute. If you store this attribute in differently, you’ll set it in the **To** field using our standard [liquidA syntax that supports variables, letting you personalize messages for your audience. For example, if you want to reference a person’s first name, you might use the variable `{{customer.first_name}}`.](/using-liquid) syntax for attributes—`{{customer.line_id}}`.

## LINE metrics[](#line-metrics)

We track metrics for your LINE messages so you can understand how they performed across your audience. See [LINE metrics and reporting](/journeys/line-metrics/) for the full list of metrics and how they work.
