10 Heuristic Guidelines we followed :-
We did a Heuristic Evaluation of an existing mail client, rediffmail. The aim was to get some insight into what is wrong with the present mail clients and how can we improve user experience in our future model of a email solution.
We got a good idea of some guidelines and frameworks which needs to be adhered when coming up with any solution. Hope we will tackle these problems, genuine problems, well.
