Disable Emails

Hi I sent email via the website but I thought I better open a ticket correctly.
I need to either turn off emails being sent to the user or I need to be able to have all items set to no prize.

At the moment When I set all items to no prize the wheel does not appear at all

When I select no tempalate it still sends the prize emails to the user

I want to turn off emails completely as we are using the plugin at a show and handing the prizes to the people directly.
