Thank you for your question. Unfortunately there is no one folder that has all of your past emails. You can however create a folder on the campaigns page and you can put in there any past emails and even current ones you may be working on in there. Just click on Campaigns tab at the top left and the down the left side you will see "Folders." You can click the plus sign and create a new Folder where you can add emails. I hope this helps. Have a wonderful day!
