Morning I would like to delete All my emails can you help

I would, but I don't have your device. Are you asking how to do this? Select the mail messages and tap on trash. If you are asking if you can select your entire inbox and delete at once, the answer is no. You can only select the mail individually. If you have web access to your mail account, that is usually the easier way to do it, depending on if it is a POP or IMAP account as well.
