There is none. If there is, they are an imposter.
Sensei is not somebody's personal penguin. He is a mascot. Thus his E-mail ID will be that of the club penguin team. So to talk to Sensei, to ask some questions about him, or to ask questions about card-jitsu games, contact the club penguin team.
the senseis password is ninjalord101
cardjitsu

There is way WAY more than just one Club Penguin email address. But if you need to contact Club Penguin, go to Community on the Club Penguin home page and there will be options to send them letters asking for help or what ever you need to talk to them about. Hope this helped.
