This would be a huge boon for us as well. We run crafting classes, and there is a variable amount of time after the class needed to fire the artwork. We want to be able to reach out once their art is ready for pickup, but this doesn't happen on a fixed schedule

There should be a link that connects with Shopify email to send a mass emailing to the entire class. This can be a button on the calendar view window. It would be very helpful for us especially when there is bad weather and we have to cancel or postpone a class due to weather or if we need to contact everyone when their projects are ready for pick up.

Similarly, being able to multi-select bookings and send them a custom email (reminder....) would be helpful
