Sending emails could get your IP blacklisted. It could also happen to your server, or even your domain. How do you ensure that you won't be labeled as a spammer? CAN-SPAM compliance can't save you from being blacklisted. It just saves you from heavy government fines. If enough people report your emails, then you have no recourse. ISPs don't care about compliance, they care about complaints.
Has anyone ever thought about this? Sure, you could always just get another domain and hosting on a different server. But, that won't do you much good. Just think of the effect of having your company domain blacklisted. That's bad, really bad.
