Hi,
In order to test your status notification email, just edit an order.
After that, you have to change the order status, to "confirmed" or "shipped" for example.
In the popup, you would find the option "notify customer".
This option would show you the order status notification email content.
So, if the content is blank, it means that there is a problem in your email.
The administrator would not be in copy of the order status notification. If you want to do it, you have to modify the email content in order to add a little PHP at the end of the file.
Regards,
