But when I try it out I don't receive any confirmation email. It seems like the deliveries are created but not being sent (editing state). Anyone has any idea why it is not working out?
Thanks for the reply. I tried to change the delivery settings first with no luck but then when I tried to change the content it suddenly worked. So you were correct that something was wrong with the template. I was able to proof it though so I am not sure what was wrong.
