The U.S. Postal Service handles 212 billion pieces of mail annually, or about two items for every man, woman and child in the country every day, according to the U.S. Census Bureau.
Statistics, extrapolations and counting by Radicati Group from May 2009 estimate the number of emails sent per day (in 2009) to be around 247 billion.
247 billion messages per day means more than 2.8 million emails are sent every second. Around 80% of these millions of message are but spam and viruses. The genuine emails are sent by around 1.4 billion email users.
A new study from the Radicati Group, Inc., brings together key statistics and forecasts for Email, Instant Messaging, Social Networking and Wireless Email. It includes data on business and consumer email accounts, user demographics, on-premises and hosted email, geographic distribution of user accounts, email accounts by business size and vertical industry, daily email traffic per user, email storage requirements, volume and cost of spam and viruses, social networking use by business and consumer users, instant messaging and wireless email use.
The number of worldwide email accounts is projected to increase from over 2.9 billion in 2010, to over 3.8 billion by 2014. However, Social Networking currently represents the fastest growing communication technology among both consumers and business users, with over 2.1 billion accounts in 2010 which are projected to grow to over 3.6 billion accounts by 2014.
Instant Messaging (IM) is also growing in popularity with both corporate and consumer users, we estimate that there will be nearly 2.4 billion IM accounts worldwide in 2010, growing to just over 3.5 billion by 2014.
