No Registrant Email Received

So I'm testing the registration system Membership Pro 2.2.1, Joomla! 3.4.8 Stable, and I'm running into some caveats:

1. User can register, but an email to the registrant is never received to activate account; only the receipt.
2. I created a User Group for new Members to be assigned called "Members", but none of them are being assigned to it in the Joomla User Group area.
3. Is there no way to activate a new registrant in the backend if I choose a different Configuration setting?

Attached are my settings.





To add: I'm also using this in conjunction with EventBooking.
