Sending and receiving emails require a client on your device such as gmail and a server that will send the email on to the recipient. It sounds like you don't have an email account set up with a server.

Perhaps your outgoing internet connection is very slow and the mails stay only for a little while in the box. If you recently did set up the mail account on hat device check if it is an STMP server the mail has to go to. You should setup the SMTP server too.
