I have a single user G Suite account. The admin UI has a panel where you can pull up some delivery information about messages using various search criteria, and you can delete messages by message id. I haven’t seen anything in the UI which would pull up the actual text of the message. However there’s additional features around data retention that may allow messages to be retrieved (e.g. for responding to subpoenas). This isn’t new or exclusive to G Suite, Exchange and Lotus Notes had similar features, even PROFS on mainframes had them.
