Google Apps added several new administrative features for email lists:
- administrators can now assign permissions per email list that determine who can send email to that list. The sending of email can be restricted to members of the list, anyone in the domain, anyone in the world, or even a subset of members designated as list owners.
- lists and list membership are easier to manage in bulk in the control panel. Mailing lists can even contain other mailing lists, which allows you to easily reuse frequently-referenced lists. We’ve also updated the Provisioning API for Premier and Education Edition administrators, which replicates all the email list functionality in the control panel, enabling automated mailing list management. We already have individual customers managing upwards of ten thousand lists using this API.
- All exisitng “email lists” are renamed to “groups”. You can access the feature from your control panel under ‘Users and Groups’ > ‘Groups’.
