Hi Phil.
Do you close the form after this submit process?
If so I have switched to the simple view at the end, then run the email submit, then close and the user never even sees it.
If not then sometimes you can add a button to the simple email summary and treat it like a confirmation button and when they click it they switch back to the default view. This can work too since you cannot do two view switches in one set of rules.
I believe you could also use code to set a specific view or create the simple summary.
