Gmail is wonderful!  I have used it for more than ten years, personally.   That is a whole lot of email accumulation!

With its Inbox, Archive, Spam, and as many Labels as you want, you can view and organize your email in many ways.

Did you ever wonder though where ALL of the Unread email is?  Whether it is tucked in a Labeled folder, or somewhere else in that mass of space ?

You can locate it easily.
