You can choose whether HeySummit automatically emails calendar invites to presenters when their session times are assigned or changed.
In the event dashboard, go to Content & Schedule > Presenters. Open the page's ... menu, choose Presenter Settings, then find Presenter Notifications. Turn on Automatically Send Presenter Calendar Invites? and select Save.
This setting is off by default, so presenters are not notified before you are ready. When enabled, HeySummit queues invites for active presenters linked to future active sessions when a session title or scheduled time changes. It also queues an invite when you add an active presenter to an already scheduled future session.
For a manual send, use the presenter's Actions > Send Session Calendar Invites option, or select future sessions and use Bulk actions > Send Calendar Invites. See Send calendar invites to speakers for those steps and the invitation status display.
A presenter needs an email address to receive an invite. Add the address to the presenter record before sending if it is missing.
