Its a functional app, BUT it keeps running in the background!!!!! After I forced closed it, cleared its cache and data, BUT IT KEEPS AUTOSTARTING WITH A RESTART AND RUNS IN THE BACKGROUND!!!!! ALSO WHY DO YOU NEED SO MANY APP PERMISSIONS!!!!! Stop straining/slowing down my hardware, even if its just a little. Its not good to unnecessarily slow down hardware, because their are many other email apps!!!!
