Dumb question about YesAsia but...

Yeah I didn't know where to put this xD Since this was mainly an Asian music/DVD site I'll post my question here.

So, the credit card I used to order HEAVEN couldn't be verified so they told me to send them information with a new card. Do I just use regular MSN email to do this or what? I was wondering since I thought that wasn't safe or something Lol XD Anyone got input? Maybe I'm just too paranoid with sending precious information over the internet through email? xD
