Triggered E-Mail Notification

I do use Practiscore for all of our internal club events - for Matches and trainings.

I do use events to setup planned trainings with a defined open and close date, so that all club members can book (and pay) for every trainings.

I do miss a notification knob, that I could send out E-Mails to all members when we do open an event and before closing the event. The idea is to inform the members that they can start to book the training (or Match) and also a second notification when the booking window will close.

Thank you for the suggestion.
