Suppose you are working for a company which sells music online. Marketing department would like to send e-mails to customers who have bought music from Web site. These e-mails would utilize information about genres of music customers have bought in past and would offer those discounts on new releases in those genres. describe your thoughts/feelings about marketing managers using the opt-in statement for permission to send such emails which would appear when customers make their first purchase. Must all businesses/organizations have opt-in statement? Or must they only have the opt-out statement in which you are automatically enrolled unless you accept/check out-out statement?
