Along with System Email templates, there is also the ability to create custom email templates for your application process.
Step 1: Click on the Application Name from the Home screen.
Step 2: Click on the Notification Center from the Manage Applications tab.
Step 3: Click on Create Template button.
Note: If creating a custom template that applies to multiple applications, you will need to select each separate application and create the template separately in each. While adding the merge fields to the templates, make sure there are no extra spaces added on the merge fields.
