MessageDesk provides users with the ability to add custom fields to contacts. You can then create filter groups based on which contacts have the same custom field values.
For example, you could create a custom field called "Customer or Staff". Then you can set this field to "staff" for any contacts who are staff members or "Customers" for any contact who is a customer.
From here you can create a filter group that contains all "Staff" members and another filter group for "Customers".
If you want help setting up custom fields and filter groups feel free to schedule a demo with me below:
