"The CAN-SPAM Act is commonly referred to by anti-spam activists as the YOU-CAN-SPAM Act because the bill does not require e-mailers to get permission before they send marketing messages.[3] It also prevents states from enacting stronger anti-spam protections, and prohibits individuals who receive spam from suing spammers."

However, no one but a fool would send to a non-double opted in list. That, however is a different discussion.

Of course dating sites have massive problems with email deliverabilty. They send out many emails to non-existant email addresses because people register with [email protected] etc. This large hardbounce number means ISPs blacklisting the IP they use and them getting shit canned. Also many send out too many emails generally that folk would THINK are spam and so hit the report spam button. Also, they send out content that I wouldn't send in terms of the language used. ie fuck this chick tonight.
