• Answer:

  ok. What you have to do is go to were you can look at just who sent them. Don't read them. At the bottom of the screen (underneth the your mail) you should see Clear All and Check All. Press Check All and all your mail should have a check mark by them. Then you press delete which is right under your mail. A box will pop up saying are you sure you want to delete and you press delete.
