Where clubs have opted to allow Online Booking of matches by players, email notifications are sent after certain actions.
When booking a Roll-up / County / National match, both the club and the player will receive a confirmation email that looks like the below.
Within the confirmation email there is a link to view your bookings which will redirect you to your account.
If the club allows it, you have the ability to cancel these bookings if needed. See Cancelling an online booking
When a player books a Club Competition, the player and the club will get an email for the initial reservation. The player, the club and the opponent will get an email if the reservation is confirmed by the player.
Only the player gets an email when the reservation expires and the reserved bookings are automatically removed.
