Creating your event reminder
In order for your event reminders to show up in the drop down, you need to have them listed as “event” types in your common responses.
Go to Settings -> Lists/Types -> Event Reminders:
https://www.pixifi.com/admin/settings/lists/eventreminders/
There you can create different event reminders to go out at specific times.
To do that, first create the Reminder template that will have all of the reminders inside of it.
Select which response to send and how many days before/after the event.
