Currently it's impossible to set an automation for reminders. You have to use email campaign for each reminder you want to set. If you have dozen of events each week it's a nightmare.

It should be possible to send an email automatically X days or/and X hours before an event, a live lesson, a meeting etc through automations.

Ideally, it would be nice if the trigger could be set with a keyword in the title of the lesson, the event, the meeting etc....
