Change the email address orders are sent to

In your Gateway account you can change the Order Email address, and the Contact Address by going to Settings > Business > Locations > Edit .

You'll note here 2 email fields. The first 'Email' is the order email address. This is where orders placed by your customers get sent to. And the other is 'Contact Email', this may be used for some notifications and is shown as a contact in the Customer's Account. If you change these and then choose Update at the bottom of the page, then that should be sorted for you.
