Receive updates to calendars on iCloud.com

You can receive an email message whenever there is an update to a shared calendar you own or participate in.

Note: You need to be on a tablet or computer to use Calendar on iCloud.com.

Go to icloud.com/calendar, then sign in to your Apple Account (if necessary).
Select at the top of the sidebar, then choose Settings.
In the Events pane, select “Email me shared calendar updates”.
To stop receiving updates, deselect the same option.
Select Save.

If you own the shared calendar, the email is sent to the address you set up to send invitations. See Invite people to a calendar event on iCloud.com. If you have been invited to the shared calendar, the email is sent to the address used to invite you to the calendar.
