Like many of his peers in ministries across New Delhi, IT Minister Kapil Sibal's office recently sent an email inviting journalists to the launch of his new personal website using the free email service.
Others, including senior foreign ministry officials, the information and broadcasting minister and the health ministry secretary, also use Gmail, Hotmail or Yahoo instead of their government accounts.
When asked why he continued to use his Hotmail for official use, Sibal declined to comment, but a senior bureaucrat in his ministry admitted that he personally preferred Gmail because it is "just a lot easier".
"We keep moving, get different designations, go different places and with that, our emails change. You lose contacts and important emails, which you don't need to worry about with a Gmail account," the bureaucrat told AFP.
"To be honest, the quality of our official mail isn't that great yet. It still needs some work," he added on condition of anonymity.
IT security expert Sunil Abraham said the use of Gmail and the like was highly risky since the American services had their servers in the US and the National Security Agency has been known to tap into their database systems.
It is unclear how many state and federal public workers actively use popular email services for office, but some of the estimates are startling.
"As much as 90 percent of government officials use private email (services) for official use... that's because their official email is not as stable or speedy," said Abraham, executive director of the Bangalore-based Centre for Internet and Society.
In September Sibal's ministry announced a new "Email Policy of the Government of India" in the wake of spying allegations about the NSA revealed by former NSA contractor Edward Snowden.
NSA's tentacles not only crept into the Indian embassy in Washington and its UN office in New York, but also accessed email and chat messenger contact lists of hundreds of millions of ordinary citizens worldwide, according to media reports.
During a single day last year, the NSA's Special Source Operations branch collected 444,743 email address books from Yahoo, 105,068 from Hotmail, 82,857 from Facebook, 33,697 from Gmail and 22,881 from unspecified other providers, The Washington Post said, according to an internal NSA presentation.
The $11 million Indian project aims to bring some five million public employees onto the government's email domain powered by the National Informatics Centre (NIC) as early as mid-December.
It is awaiting clearances and suggestions from all ministries before the proposal goes to the cabinet this month.
J. Satyanarayana, secretary of the department of electronics and IT, dismissed claims that the policy was too late and was a response to the Snowden scandal.
"The policy is not a reaction to any global spying revelations, it was already in the works. It is just a mere coincidence that both came around the same time," he said.
Some cyber security experts say bringing millions aboard a centralised server could make a hacker's job easier, with all critical government information available on a single platform.
More than 11,000 Indian websites were hacked or defaced between May and August this year, with a large number of attacks on the ".in" domain whose servers are in India, the Times of India reported last month.
"Making the use of a centralised government server is not the best way to proceed. Having everything on one platform makes it even more vulnerable to cyber attacks and hacking," said Abraham.
"It also brings about new worries of the NIC becoming the local snoop."
Some also predict that the ambitious policy would eventually fizzle out for lack of attention from ministers and bureaucrats, who work in government offices where stacks of yellowing files and papers are still a common sight.
"It's sad but most of these officials don't understand much about technology, so mastering email is something that is miles and miles away," said Vijay Mukhi, a Mumbai-based cyber security expert.
"These guys saw all the snooping news and suddenly they woke up and said 'lets make an email policy'. Enforcing this is not possible on a practical basis."
The IT ministry also plans to conduct workshops to teach employees about email security such as when to change passwords and user names and how to use email.
"Every employee should know how, what and when critical data can be vulnerable... with most work still done on paper, it is important to know the nitty-gritty of using email," Satyanarayana said.
