Not to mention that most email has roughly the same security level as a postcard. There are a lot of personal details that I wouldn't want written on a postcard. Not to mention the fact that lots of 'personal information' is not in fact private, e.g. date of birth (one of my financial accounts uses date of birth), mothers maiden name, social security number, etc.
