Hey there, Brian! Thanks for getting in touch.
I imagine that auto-generated emails would be possible with a third-party plugin. I don’t have one off the top of my head, but here’s a search to help you get started. The important thing is to find one that support custom post types, since that is what events are.
And, yes, the Facebook Events add-on will automatically import events for Facebook pages that you do not own, as long as they are public. Good question. 🙂
Does this help answer your questions? Please let me know.
Cheers!
Geoff
