I recently added a batch of new members to my PTA group (thanks for the timely approval!). That is a primary group which has subgroups.
In the body of the notification the new members received only the primary alias was given, which I think is insufficient. For groups with subgroups the subdomain name should be shown as well. For example:
Subject: You have been added to the email@example.com email groupI recommend that the group name be shown there as "members@example" for clarity and for consistency with the usage in the rest of the message.
