Answer 1

I think you want once anybody have read email ,you will find notification.

I think you need to send a link with a mail to confirm,

otherwise its not possible ,because its not allow from gmail. 

Answer 2

There is no direct way to get the Mail read status from outside of the email box. However, there is a hack for this and refer the below link for more details.
