When I checked I see my email is taking up 649MB. But only a few on iPhone. And I have deleted sent and emptied trash. So what am I missing. And why is it taking up so much space.
You may have or had more than one account on your phone. I have 3 on mine. If you had more than one acct try re- activating tun delete unwanted mail. Or try xcleaner apk to delete temp folders.
