When important events in a control flow occur, it is often necessary
to notify someone in an e-mail message. An e-mail operator sends e-mail.
After placing an e-mail operator in the canvas, you can select it to view and define its properties, such as sender, recipient, subject and message. You must specify the recipient and the text of the message that is sent. Sender and recipient can be set as variables.
You must connect an e-mail operator to another operator in the canvas in order to specify how the e-mail notification is related to other operators in your control flow.
