Punchpass has the ability to send class reservation confirmations to the customer who made the reservation, the appropriate class instructor, and to the administrator!
Here's a little cheat sheet about how Punchpass communicates class reservations that have been made.
Punchpass also lets you know when a reservation is canceled
If a customer cancels a reservation we send you (the administrator) an email, and if the instructor is set up to receive emails we'll send one to them too. If you don't want to receive these emails you can turn off this feature in Manage Settings > Online Reservations
