Email notifications are not working

Hello,

I have just installed the lite version to try the plugin out and I love the design. However when a customers makes a booking (I set them to be pending) they do not receive a notification about the booking. Neither do I. I can’t find where to accept these bookings. I do not receive any emails and neither does the customers. Even though this is a lite version I surely do not expect something as basic as email notifications is a premium feature. And i am the admin. How do I make this possible?

Everything is set up correctly. So it should work.
