Assume you are working for a company that sells music online. The marketing department would like to send e-mails to customers who have purchased music from the Web site. These e-mails would use information about the genres of music customers have purchased in the past and would offer them discounts on new releases in those genres. Write the text of a memo (about 200 words) in which you make a case to the marketing manager for using an opt-in statement for permission to send such emails that would appear when customers make their first purchase.
