To Preview the Message. Feedforward messages may, for example, preview the content (“I’m afraid I have bad news for you”), the importance (“Listen to this before you make a move”), the form or style (“I’ll tell you all the gory details”), and the positive or negative quality of subsequent messages (“You’re not going to like this, but here’s what I heard”). The subject heading on your e-mail illustrates this function of feedforward, as do the phone numbers and names that come up on your caller ID.
