If you install Dialogue afterward, you can manually trigger the integration check via the Unity toolbar: **Game Creator > Mailbox > Detect and Install Integration** {% endhint %} If you want to use dynamic values inside a letter, such as {Player}, which automatically replaces the placeholder with the actual player’s name, you need to change the Text Area or String inside the letter asset to a Dynamic Text Area or Dynamic String, depending on whether you’re modifying the letter’s body, title, or sender. {% hint style="warning" %} **Warning** Changing the **title, sender, or body** to a different type (**Dynamic String** or **Dynamic Text Area**) will **erase all existing text** in that field. Make sure to back up your content before making changes! {% endhint %}
