For customers and business admins, please first check that you have enabled / haven't disabled notifications. You can do this from your Profile > (Settings on the mobile app) > Notifications page.

Please check that your correspondence email is correct. You can check this under Profile > Edit Profile.

Please check that the emails have not gone to your junk folder

For business admins, please note that it is the set host instructor of a session who receives booking and cancellation emails, so please check you have set that field in the session set-up fields. If you are not the host instructor but still want to receive the emails you can ask the host to amend their correspondence email address.
