If you're an "inbox zero" kind of person, it's best to read every email only once and reply to it, file it or trash it immediately. It's best, but it is not always possible.

If you can't deal with a new message in Yahoo Mail immediately, you can star it so you don't forget to return to it later.

While marking to-do messages unread works, a dedicated, more elegant and generally better way to flag emails for follow-up relates to message stars; these flags are particularly useful in Yahoo Mail if you use them with ​Message Views.
