Same! We're transitioning away from eventbrite... Eventbrite integrates to mailchimp no problem: easy to send follow up emails triggered by event check in. Would like to be able to do this via squarespace if possible: track customers attending events (via service product purchase).
But really why have events at all - why don't service products have a time and date field??? Essential for tracking the customer journey of our class attendees.
If anyone knows how to send automated emails triggered by event time, please let me know.
