The best part is that I can access my emails even if i am in some remote location without having an internet connection. It's really great because sometimes our mobile phone data plan gets interrupted or blocked due to lack of signal. So accessing emails becomes difficult. They are charging me for each message transferred through their app. If it was free then there would be no problem at all. Also they do not have any customer support team. Try them once before making decision otherwise you will regret later. We were facing issues while sending mails with gmail account.
