Government agencies should send printed notices by postal mail to senior citizens

At present a large number of senior citizens are living alone or do not have children. They also do not have a computer at home for accessing email. Since income tax returns are being filed only once a year, their relative living in a different city may help them file the return.
However,if there is any problem and the government department sends a notice, the senior citizen may not be able to access the email. The relative will have to take a printout and send it usually by post, and there are delays.
So the government agencies should be aware that most senior citizens in india do not have internet access and send any notice or letter to them directly by postal mail
