Webcast Webinars (Classic)

Webcast webinars (formerly called "Broadcast Beta") allow organizers to host large, broadcast-style sessions with up to 3,000 attendees (Plus plans) and 500 attendees (Pro plans) in listen-only mode. This allows organizers to reach bigger audiences with even greater engagement, while ensuring as smooth a join as possible thanks to the browser-based Instant Join app.

The features that are available on your account may vary depending on your subscription plan.

Webcast FAQs

How do I manage audio settings?

When you schedule a webcast webinar, it will detect your account's default audio settings and automatically apply them to the session. Unlike with classic webinars, it is not possible to modify a webcast webinar's audio settings once it has been scheduled.

  • Organizers, co-organizers and panelists will be given whichever audio options the organizer has specified in their default audio settings.
  • Attendees will connect to audio via Computer (VoIP) by default.

If you would like to change which audio options are available for staff during a webcast webinar, you must first change your default audio settings and then schedule the webinar.

Note that custom audio information is not available for webcast webinars; only GoToWebinar's built-in audio modes can be used.

Can I schedule a classic webinar with 3,000 attendees?

No. Only webcast webinars can include up to 3,000 attendees (Plus plans only) and 500 attendees (Pro plans). Classic webinars will continue to have a 1,000 attendee limit.

How will my attendees join?

Organizers, co-organizers and panelists will join the webinar using the desktop app, the same as with classic sessions.

However, Windows and Mac attendees will be directed to the no-download, browser-based Instant Join app – regardless of their operating system. This means that they will join the webinar entirely through their web browser, without needing to download the GoToWebinar software!

Mobile attendees can join using the GoToWebinar app on their device.

How do I unmute my attendees?

Webcast puts attendees in listen-only mode; only organizers and panelists will be able to unmute themselves. Attendees cannot be unmuted.

How do I switch my scheduled webinar between classic and webcast?

Once a webinar has been scheduled as classic or webcast, it is not possible to later change it. Instead, you can schedule a new webinar using the desired mode. Please note that if you copy the webinar, it will keep the same mode as the original one (i.e., if you copy a webinar in webcast mode the new webinar will also be in that mode).

How do I promote attendees to co-organizer, panelist or presenter?

It is not possible to promote attendees during a webcast webinar. If you would like an attendee to become a staff member, then you must add them on the Manage Webinar page. Then they will need to exit the session and rejoin using the special co-organizer or panelist Join URL that you provide them.

Can I add a password to my webcast webinars?

No. Webcast webinars cannot be password-protected.
