How To Update Group Default Email Notification Settings

When adding members to a group, it can be helpful to set the default email notification settings so that all new members get the same communication experience, before they decide to  set it for themselves. 

For some groups, you may want it to be set to 'No Email' whereas with other groups it can make sense to have it set to 'All Email'

To update the default settings go to any group you are an admin of, click on Manage > Settings

Then scroll down to the bottom of the Settings page to the Email Subscription settings to select the option that makes sense for that group.
