I've recently installed the Google Checkout module and I've noticed that instead of my site storing the customers original email address, I'm now getting a google checkout assigned email address instead, meaning that when I amend the order via my site the message isn't being sent direct to the customer. Also I no longer have their email for my newsletters.

Is there a way around this?
