Notification messages are based on a message template that determines the format and contents of an e-mail notification message, including the message subject and body. A template is an HTML-formatted document that you can view or change as required to customize notification messages. The template text may include dynamic content that is generated at run time by retrieving information from the running instance of the workflow process. Notification messages are created, and normally sent, in HTML format. You can optionally configure the activity to format and send notification messages as plain text.
