Hi there, Adrian!
Good question. Sending email reminders prior to and event isn’t currently supported right out of the box.
However, you will have the email addresses of those who have purchased tickets, so it would certainly be possible to export that list and import it into an email marketing system like Campaign Monitor or MailChimp, where you can set reminders up for your ticketed events.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
