It's legal to send requested information to some zip codes, and illegal to send requested information to others... don't know about unsolicited info, though.....
If you mailed one envelope inside the other, with the 'sensitive' content on the inside of the inner envelope with a damn good warning for minors and others that may not want to view adult material written on the outside of the inner envelope....
Then (maybe) opening the inner envelope would be 'opting in' to view your 'sensitive' content...
