The default e-mail program installed with Mac OS 8 is Claris E-mailer lite.
 

Files can be viewed as icons, buttons, or lists. Folder Windows can be dragged to the bottom of the screen where they appear as tabs that can be pulled out.. The new appearance manager has a built in window blind effect that reduces windows to just a title bar by clicking a button on the right side of the title bar.

Further folder customization lets you change the size of the icons or buttons in each folder and more.

Finally, MacOS 8 uses several "assistants" (or wizards in Microsoft-speak) to guide users through a series of complicated tasks.
