We have started rolling out our new Social Sharing feature to Event Campaigns. If you do not see this yet, you will be seeing it soon!
Have you used Social Share before? The process is very similar, allowing you to schedule multiple posts for your event. The main difference is instead of having 3 set posts, the posts will be spaced out up until your event start date. This means that if your event is a little ways away, you will have more automatically scheduled posts created for you. Don't worry though, you can always delete or add posts as needed.
Please note: This feature is only available once an event has been made live.
