# Body Template

In the body field, you can write the message body with a maximum of 1024 characters. This message body is mandatory because it contains what you want to convey to the customer. Then, if you have entered the message body, a preview of the message body will appear on the left side of the page.

![Message Body](/files/-MUNPf3mjXRc8YTzuwgu)

In the body of this message, you can also add a variable with **{{#}}** which will later be replaced by a string. The number represents the index variable.

For example in the picture above, after the variable {{1}} and {{2}} is created, when you create a notification (go to the [**Notification > Create Notification**](/5.1.x/marketing/notification/create-notification.md) menu) using that template, in the message form you will be asked to fill in the variable index 1 and 2, then the variable {{1}} and {{2}} will be replaced according to the index variable you entered, as shown below.
