Is there a way I can send all subscribers an email?
There's no way independent of events to send all subscribers an email.
Once upon a time, the deletion of a calendar event provided an opportunity to email subscribers. Now that only happens when you delete repeating events -- when you delete a single event, you have no ability to send an email. That seems like a bug to me; the cancellation of a single event is at least as important to notify people about as a repeating event.
A possible (admittedly awkward) workaround would be to create a repeating event that is just like the original event (at least has the same title and is on the same calendar), but only repeat it for one occurrence; but don't send an email to subscribers. Then delete that event and make sure you check the box to notify subscribers. Note that you can't use the right-click "Delete Only This Event" option to do this; you have to click on the event, and then click the "Delete Event" button. That should send an email to all subscribers informing them of the deletion of the event, which as far as they can tell will appear to be telling them about the cancellation of the original event.
