No notification of new email received on SGN4 lock screen

Can anyone please advise on how to activate a function that will allow me to view lock screen notifications when an email is received just as I can with missed calls and sms messages etc. The only way I become aware an email has been received is by noticing the addition of a status bar icon once the phone has been unlocked. If it helps I am currently using the stock email client and run with kitkat 4.4.4. To date I have tried all I can to find this facility but to no avail. Many thanks in advance.
