Did you know that you can subscribe to email notifications for the events created in Company Calendar Planner?
Starting the app version 6.0, Jira admin can enable the email notifications via app configuration:
Once the email notifications are enabled by an admin with the right to override, users can configure the notifications according to their needs and preferences: User Settings and User Guided Tour
If needed, you can subscribe to Company Calendar event notifications via calendar export to Google calendar. First, you would have to export the calendar created in the Company Calendar Planner to the Google calendar.
Then, click on the ellipsis next to the exported calendar’s name to open its settings.
In Settings, you can add notifications based on your preferences.
