E2 - If an email message is sent with promotions or ads from 4 different companies, the company who is the primary sender is the only one which needs to comply with the act as it is they who are communicating with the consumer. The additional "ride along" ads should be exempt from opt-out concerns. F - A do not email registry is a non-workable solution that leaves open the opportunity of theives/scam artists/spammers to do just the opposite and email the names on that do not email registry. The core problem with email is that it is without cost and until such time as ISPs charge for delivery of bulk email, no amount of registries will solve the problem. Adding a do not email registry will only cause costs and challenges for legitimate firms sending email to their own customers and create the opportunities for more spam email as I've noted above.
