Be sure to print out the email with the serial too... you have no idea how many times I've had to dip into my "serial number emails" file folder in my filing cabinet due to glitches, hard drive mishaps, and OS reinstallations. Outlook email folders are pretty much non-recoverable once the OS is borked. Even when you don't think you'll need it, print it. I've had stuff that was three years old that I've had to try and track down on various manufacturer's websites because I needed it for one reason or another. Heck, I'm thinking of printing all my serials on one sheet of paper and laminating it. :P
