Hey Al,
Great question! I’m afraid that the calendar does not currently support automatic email notifications before an event. However, Event Tickets does allow you to collect the names and email addresses of people planning to attend your event, which can be exported and used to email them. You may also want to consider the use of a notification scheduling plugin, like Mail Poet to help schedule those communications.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
