Webcast Webinar Events

Webcast webinars 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 a smooth join thanks to the browser-based Instant Join app.

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

Make sure you are running a supported system.

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. Note that only GoToWebinar's built-in audio modes can be used for Webcast webinars (VoIP and PSTN). Unlike classic webinars, it is not possible to modify a webcast webinar's audio settings once it has been scheduled.

  • Organizers, co-organizers, and panelists can connect to audio via VoIP (Computer audio) or PSTN (Phone audio).
  • Attendees can only connect to audio via VoIP (Computer audio).

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.

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?

Attendees are put in listen-only mode and cannot be unmuted. Only organizers and panelists will be able to unmute themselves.

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.
