Marketers are required to add an unsubscribe button to their emails to give the consumer the option to opt out but that doesn't have to mean the end of the relationship. Marketers should take advantage of the opt out and ask consumers why they are quitting in an attempt to learn more about the customer. Many consumers want to opt out because they receive too many emails from a company and simply giving customers the chance to control the frequency of the emails will save the relationship.
