There are more similarities between free, consumer Gmail and Google Workspace than there are differences. In fact, Google Workspace can be viewed as a multi-user version of consumer Gmail.
When a single user platform becomes multi-user, an administrative level is needed for tasks such as adding and deleting users, creating groups, assigning apps and managing security.
Fortunately, adding users to Google Workspace is a straightforward process for an admin. The creator of a Google Workspace account is a super administrator by default. One or more admin roles can optionally be assigned to any user. One of the admin roles is called User Management Admin. This role allows a user to create, delete and update individual users (other than admin users).
Only a super administrator, however, can bulk upload new users.
