Postal services have come a long way since the days you posted a letter and
prayed it reached. The Indian Postal Service is owned and managed by the government.
It is a pretty efficient system and provides a wide range of services. Key among
them include financial services (banking, money transfers, issuing life insurance
policies, distributing mutual funds and securities, electronic clearance services
etc): speed posts and a host of other online services.
