We provide a welcome letter to our indirect loan customers that provides customers with information on online/mobile banking to access their loan account, as well as information on payment options. The email also contains a tidbit about other products. It simply states to contact a bank customer service representative for information about our other products that may fit the customer's needs. Specific details about these other services are not provided. Does this trigger CAN-SPAM requirements? The primary purpose of the email is transactional/relationship, but does the tidbit about other products make it commercial? Again, wondering if the CAN-SPAM requirements apply. Thanks!
