Every company that proceeds that kind of marketing has to pay great attention to the unauthorised email addresses so that you will not get into big trouble with law. To sort out everything so that you will not be reported as a spammer you need to have the agreement, mentioned before, best way to get it is to enclose a form to fill in with a bracket asking for an email address.
