dscurlock wrote about big spammers never going to jail - of course not ! That's not a criminal code, that's a civil code according to which they are being penalised. In regard of to the thread question - you can ONLY bulk mail people if they gave you permission (the ONLY case of the permission is subscribing to your mailing-list). BW Edit: sorry, just noticed jigordon already answered the question as same as me.
I never go to web sites on spam email. Now a days people know what spam is and don't generally trust them.
