Message ComposerMessage Composer is the tool that helps you create your notification message text easily.
It supports auto-suggest feature as well as quick tags pasting.
You will find Message Composer in Consider Email, SMTP Email, Slack and Pushover actions.
Other third-party integrations use their own website interface for setting up the notification.
Interface is pretty simple. Just start typing and click on the relevant tags in the lower part of the screen.
Click anywhere outside the Message Composer window to save the contents.
