Event Campaigns currently allow us to set emails to send a number of days before and a number of days after the event, but there is no option to send a reminder the day of, or at a particular time. Particularly for webinar events, it would be helpful to send the reminder on the day of the webinar. We would also like to be able to send a thank you immediately following the event, instead of having to wait a full day from the event to thank attendees for their time.
