Google Groups
Google Groups provides a convenient way for your users to send messages to groups of people they frequently contact. A group contains the email addresses of its members, so users can send a message to all the group's member's using the single address for the group. Users can user groups to more easily:
- Communicate and collaborate with groups of people
- Manage access to your documents, sites, videos, and calendars
Google Apps Google Groups are hosted in your domain (group@my-domain.com) and are limited to the users in your domain.
To access these groups, navigate to Directory > Groups
