Worst email app ever! Replies don't get saved on the server or in the sent folder! So it looks like you never replied to emails! Once you reply to an email, the original message in the email disappears and it looks like you replied to an empty email! Notifications are extremely unreliable despite having it checked several times. Many emails just appear as "no content" messages. If they were trying to make the worst email app in the history, then they truly succeeded!
