Re: how do i stop deleted emails fromcoming back.
Welcome to Android Central! Is this on the stock Email app? Are you using the POP3 server or IMAP server? It sounds like you're using the POP3 server--there is often a setting to delete or keep the original email on the server, either in the Email app's settings or on your email provider's webmail page. You should also consider switching to the IMAP server, which is a bit more modern.
