Send notifications to your open channel.

## Creating content

<p>When creating messages, you configure its appearance in the Content step. In the Delivery step, you can configure content-related features that do not affect the appearance of the message.</p>

In the *Content* step, click **Custom Message**:
   ![Open channel content](https://www.airship.com/docs/images/content-open_hu_ff454e0795aa9816.webp)

Now you can configure the body of the message:
   ![Open channel content](https://www.airship.com/docs/images/composer-content-open_hu_d7e540bb74030620.webp)

1. <p>Enter the message text. If you are using [Handlebars](https://www.airship.com/docs/reference/glossary/#handlebars), you can test how the content will appear. See <a href="https://www.airship.com/docs/guides/personalization/previewing/">Previewing personalized content</a>.</p>
