No surprise here - we use Google Workspace, and which throws in a bunch of benefits - as well as charges for each member of our team.
So an organization wide email list like 'marketing' or 'blog' would be nice, so we don't have to keep track of lists of names, etc, on an individual basis - sure, everyone can manage their own distribution list, and that is fine - don't not do that.
So included in the Workspace is the old Google Groups chat room thingy. It is now settled into a fancy email distribution list with some extra features, and it meets the need I see we have.
In the admin panel, there is hiding the Groups for Business settings. This is where you can set up organization wide setting to do with Groups. https://admin.google.com/ac/appsettings/864450622151
But not actually creating groups... There are obscure settings here to do with who can send or join and possibly, these are in flux, as some of the Google Help seems to contradict what is now available in the settings.
Creating a group is done through the Directory, under Groups, (eg https://admin.google.com/ac/groups/01rvwp1q1piem8u/members) and easy enough to create new groups, and in short order, marketing, info, and blog can be created.
But this post is really to record the fact that this is possible, and this is where it is controlled, setup, and managed.
