If your account has an external event calendar, you can add your webinars by associating them to custom event fields.

Select or fill out the custom fields so they match the tags of the event calendar you want the webinar linked to.

Click Save.

2 Display webinar on event calendar. Click Marketing from the left-hand navigation. In the Webinar promotion section, to the right of "Display on event calendar," click Edit.

Select Yes. Click Upload and choose a cover image from your computer or network. Click Save.

Your webinar will display in your external event calendar with matching tags.
