If you have ever notice while browsing on gmail we always get advertisement and links related to our email content in right side of window. For example if I m seeing email about semantic web then I will be getting other related links about advance web. it shows when we received some message on gmail then automatically it open our message and steal some key words from it and show related links but isn’t against our privacy rights.
Undeniably I ll get upset if somebody enters to my house with out permission and same doesn’t matter to me that whether he/ she came for help. So instead of opening emails from user account directly, more featured can be provided to personalization as this facility already available on for google and gmail.
