Can’t remember whether you sent an email? No need to worry; you can check a list of all the emails you have sent by going to your mail home screen (the screen that has the Inbox, Trash, All Mail, etc.,) and click on Sent Mail. It may take a while to load if you haven’t checked this section in a while, but eventually, a list of every email you’ve ever sent will appear in the folder.
Have fun with your iPad!
