Honoring customer privacy. Confirmation email does not have to list billing and shipping address, amount, telephones, etc. I just need quick update: "your XYZ title was shipped, for more info see your orders".
I my case I would turn the confirmation off completely. Why we have secure accounts, just to send plain text afterwards? What has shipping address to do with electronic downloads anyway. This 'convenience' can bring more hassle than value.
