You can access your “Distribution Lists” through the dashboard.
1) Click on the plus icon at the top-right corner.
2) Enter the distribution list Name, Email, and Lookup*.
*Lookup means the manager for this list who should be one of the users listed.
3) Click on “Save Changes”.
-When you create a distribution list, it will not be an accessible mailbox; that is, you cannot open it as it’s just used for sending emails for a bulk of members.
