How can a general user tell if a Contact listed on a sheet is a licensed user?

As a paid licensed user WITHOUT Admin privileges, is there a way to tell if a Contact listed on a sheet is a licensed user (free or paid) vs someone manually entered?

Use case: Automations allow messages to be sent to "Limited" users in the same account or "Unrestricted" any email referenced. However, all contacts visually look the same on a sheet whether they're a free or paid licensed user, or a contact entered manually. How do I know the difference so I can make an informed decision about my automation?
