Hi Eric,
1. Unfortunately we do not have a way to disable these emails, but I do think we have a workaround for you (see part 2).
2. My suggestion here would be to create a few test/fake profiles under your own account and use those as attendees. You can give them names like Eric Test 1, Eric Test 2, etc. This would allow you to control the email address for each test profile so that all of the notification emails come to you.
