On the settings: Send the site admin emails - all are checked.
Checkout: when a member checks out.
Admin Changes: when an admin changes a user's membership level through the dashboard.
Cancellation: when a user cancel's his or her account.

However I am not getting the checkout emails in 188.8.131.52 and 184.108.40.206, but I did just get and admin change email.
