I always thought the idea of spamming is that you put something in the message.
I just got a blank email from Barclycard today. Yup totally blank nothing in it. I wonder if they got a virus on there system.

Maybe it's one of those mails that remotely loads something and you played with the security/privacy settings in your mail client and it blocks that ?
