Hello Mark,
The best solution for your requirement is to use our email forwarding feature. You can dedicate one of your DriveHQ email addresses solely for the purpose of forwarding notifications. To set this up, go into your DriveHQ email account -> Email Options -> Email Auto Forward. Add the email addresses where you want the notifications sent (separate each one by comma). Then, in the drop box notification field, put the email address of this account and the notifications will be forwarded. This solution will work very well as long as you're not using the DriveHQ email account. If you are, you can set up a subuser account and utilize their email address.
