I can't get out of my email on my iPhone?

Added (1). I have not found a way to sign out of my email on my iPhone!

Hmm, just close the app

Try restarting your phone. If that doesn't work, you might just need to reset your whole phone.

Settings > Passwords & Accounts, select your account and delete it or disable mail for that account.

You don't sign out (using the stock Mail app) you just delete/disable the account from the same place where you added it.
