Updating your marketing plan
It's not only effective but convenient as you can send messages through both channels with one click (Request more information about the Whova’s announcement system).
If you happen to use the Agenda Center for your event website (shown in the Step 2), your speakers can conveniently promote their sessions on social media with one click.
Updating the agenda across platforms (website and mobile) is efficient.
I appreciate being able to make quick updates in one central location.
You and your sponsors / exhibitors share the same goals in terms of attracting more attendees at your event and increasing brand visibility.
You should use this common goal to motivate them to participate in promoting your event.
In general, event listing websites such as Eventful, Hey Event, and 10times, are good places to promote your event, regardless of the age of your attendees.
