Issue
When using the the GoToWebinar plugin, it will generate a select list based on synced contact history. Webinars that have not started syncing contacts to Campaign Studio will not show up in the list.
Resolution
There are two possible workarounds here:
- Manually upload lists of registrants/attendees into segments and use those conditions
- Register a "fake" contact to the webinar and let it sync to Campaign Studio. That should create a sync record which will then show up in the dropdown list.
