Manage Email Notifications in Google Calendar

Google Calendar generates tons of email notifications. When you are a heavy user, this can be overwhelming. 

Two areas to manage (reduce) the email notifications from Google Calendar are notifications about events and notifications about invitations for events.

• Open Google Calendar.
• In the top right, click Settings    Settings.
• On the left, under "Settings for my calendars," click the calendar you want to change  Calendar settings.

• Under "Event notifications" or "All-day event notifications": 
  • To delete a notification, click Remove notification
  • To edit a notification, choose if you'd like to receive a notification or an email. Select how long in advance you'd like to get the alert. 
• Under "Other notifications": 
  • Change Event Responses to None.
  • Change other settings to None here, too, as desired.
