Compose effective subject lines for the following persuasive email messages:

a. A recommendation was sent by email to your branch manager to install wireless networking throughout the facility. Your primary reason is that management has encouraged more teamwork, but teams often congregate in meeting rooms, the cafeteria, and other places that lack network access—without which they can’t do much of the work they are expected to do.

b. A message to area residents soliciting customers for your new business, “Meals à la Car,” a carryout dining service that delivers from most of the local restaurants.

c. An email message to the company president, asking that employees be allowed to carry over their unused vacation days to the following year. Apparently, many employees canceled their fourth-quarter vacation plans to work on the installation of a new company computer system. Under their current contract, vacation days not used by December 31 can’t be carried over to the following year.

d. Your boss has asked you to post a message on the company’s internal blog urging everyone in your department to donate money to the company’s favorite charity, an organization that operates a summer camp for children with physical challenges. You wind up writing a lengthy posting, packed with facts and heartwarming anecdotes about the camp and the children’s experiences. When you must work that hard to persuade your audience to take an action such as donating money to a charity, aren’t you being manipulative and unethical?

Explain.
