Define Message Content

You can define message's subject, body, and format.

Message Section	Action	Required/Optional
Subject	Type a subject for the message. (Optional) Click the ellipsis button next to the subject text box to create an advanced expression.	Required
Body	Type a body for the message. (Optional) Click the three dots next to the body text box to create an advanced expression. When you use an expression that contains HTML content (such as form data, HTML forms, HTML controls, rich text editors) in the body section of the Email Activity or Message activity, you need to wrap the expression inside {{= }} to render the expression in HTML format. For example, `{{= {Form1}.Query("Form1")["Editor1"] }}`.	Required
Message Format Drop-Down List	Select a message format. HTML (default) HTML (markup only) Plain Text	Optional
Calculate Per Recipient	Select this check box to calculate the message fields and attachments for each recipient. If you do not select this check box, the message fields and attachments are only calculated one time.	Optional
Localization Mode	Select a localization mode. Default: Use the culture of current thread (i.e., the culture of the system that is creating the message) Inherited: Use the culture of the message's parent, which is generally a workflow. If the message does not have a parent, this is the same as the default option. Recipient: Use the culture of the message's recipient. Note: Culture means language and other localized formatting.
