Must be me but how do you list only specific items received like only one from Hospital or only ones from energy firm?
I do that by applying tags to specific email adresses via rules on received mail.
And then I only select specific tags (for example Family, Friends, Bills, Specific clients, Amazon & eBay, etc.).
Another option is to create a Search Folder that only displays messages from a specific sender, or contains certain key words etc.
You can find out more about Search Folders in the Help File (F1) here.
