I respect that some of this is ass-covering because of overreaching regulation (or in many cases probably overly-conservative readings of the vague regulations) especially with respect to HIPAA and Euro-style "Privacy" legislation, but personally I'd prefer to opt-out of all types of nanny-ism trying to 'protect my privacy' by sending me content-free email with links, that then require that I 'click to view' and then, 90% of the time now, return to my fucking email to retrieve a stupid code.
