Not all webinars have a single host. Two or more can work together to enhance a presentation! Inviting someone to co-host allows them early access to your webinar for setup and preparation. 

You can have up to three co-hosts. A total of four people (including you, the host) can present with a camera and mic. 

To co-host a webinar, a WebinarNinja account is required. If your co-host doesn't already have one, they will be prompted to sign up for a free account upon accepting your invitation to co-host. 

Important: Be sure to invite your co-host ahead of time as co-hosts cannot be added during a webinar.

Adding a co-host

You can add a co-host in the process of creating a webinar by clicking +Add Co-Host.

To add a co-host to an already existing webinar:

Step 1: Click the My Webinars icon on the sidebar. 

Find the webinar in which you want to add co-hosts. Click Options to the right of it then click Edit Webinar from the drop-down.

Step 3: Click +Add Co-Host.

Step 4: Enter your co-­host's name and email address in the window that pops up.

Step 5: You can edit the auto generated email to your preferences. The email will have two links which are both required: 

The first link is to register the recipient as a co-host to your webinar. It will prompt them to log in to their own WebinarNinja account or sign up for free if they haven't already (there will be no credit card required).

The second link is for them to access the webinar studio.

Email tags are shown on the right side. Click or copy and paste them to auto populate the email with appropriate information about the webinar.

Step 6: Click Save.

Your co-host's name will now be listed.

You can add up to 3 co-hosts. Click +Add Co-Host again to add more.

Step 7: When you are done, click Update Webinar

Your co-host/s should immediately get the email invitation afterwards if the webinar was already published. Otherwise, the invitation is automatically sent after publishing the webinar.

Checking in on the invitation

Your co-host needs to click on the first link in the email invitation to accept it and be registered. If they do not already have a WebinarNinja account, they will be prompted to sign up for free.

To check if your co-host has received and accepted the invite:

Step 1: Click Options to the right of the webinar and click Manage Co-Hosts.

Step 2: See what it says under Status. Before your co-host accepts the invitation it will say Invite Sent

Clicking the envelope icon under Actions resends the co-host invitation.

Once your co-host accepts the invitation, it will say Confirmed.

They will be featured on the registration page next to you as shown below.

Clicking the trash bin icon under Actions cancels the invitation and removes the co-host from the webinar.

Here’s a guide for your co-host to accept the invitation and join the webinar.

Note: Co-hosts will not receive any of the email notifications sent to attendees-including the replay email. Have co-hosts register for the webinar as an attendee with a different email address to be able to access the replay.
