Our marketing department is considering sending marketing emails to our existing customers, using a third party vendor. Our current privacy policy says we don't share except for servicing, etc., so I am wondering if by using the 3rd party, we would have to change this and provide the opt out disclosures as we will now be sharing for marketing purposes. If we merely give this firm the customers email address and nothing more, would we have to change the privacy policy as long as we disclosure on the email a link where they can notify us to discontinue emails?
