Configuring Email Notifications for Groups in Grid
To configure Grid to receive email notifications for the group on every post:
From your org home screen, select Salesforce Chatter from the drop-down menu on
the top-right of the window.
Click the Groups tab.
Click any group where you are a member. Select Email Daily Digest or Email on
Every Post depending on your preference. If you select Email on Every Post, you
see the email anytime someone @mentions that group.
As the creator of the request in Chatter, you won't receive @mention email
notifications to yourself or the group where you are a member.
