Not receiving any notifications for appointments booked or not sending confirmation emails?


At the moment I have been testing the plugin, I have gotten a few different people to test it for me and I am not receiving any notification of appointments being booked unless I click "pending appointments". Is this normal?

The appointments are being registered, when I click confirm and send confirmation email, the clients so far haven't received anything.

I think i have the right things clicked in the settings section.
