Question: How Many Emails Are Sent Every Day?

Answer: Statistics, extrapolations and counting by Radicati Group from April 2010 estimate the number of emails sent per day (in 2010) to be around 294 billion.

294 billion messages per day means more than 2.8 million emails are sent every second and some 90 trillion emails are sent per year. Around 90% of these millions and trillions of message are but spam and viruses.

The genuine emails are sent by around 1.9 billion email users.

In the United States, text messaging is also popular; as reported by CTIA in December 2009, the 286 million US subscribers sent 152.7 billion text messages per month, for an average of 534 messages per subscriber per month.[33] The Pew Research Center found in May 2010 that 72% of U.S. adult cellphone users send and receive text messages.[34]

In the U.S., SMS is often charged both at the sender and at the destination, but, unlike phone calls, it cannot be rejected or dismissed. The reasons for lower uptake than other countries are varied—many users have unlimited "mobile-to-mobile" minutes, high monthly minute allotments, or unlimited service. Moreover, push to talk services offer the instant connectivity of SMS and are typically unlimited. Furthermore, the integration between competing providers and technologies necessary for cross-network text messaging has only been available recently. Some providers originally charged extra to enable use of text, further reducing its usefulness and appeal. In the third quarter of 2006, at least 12 billion text messages crossed AT&T's network, up almost 15 percent from the preceding quarter.

In the United States, while texting is widely popular among the ages of 13–22 years old, it is increasing among adults and business users as well. The age that a child receives his/her first cell phone has also decreased, making text messaging a very popular way of communication for all ages. The number of texts being sent in the United States has gone up over the years as the price has gone down to an average of $0.10 per text sent and received.

In order to convince more customers to include text messaging plans, some major cellphone providers have recently increased the price to send and receive text messages from $.15 to $.20 per message.[35][36] This is over $1,300 per megabyte.[37] Many providers offer unlimited plans, which can result in a lower rate per text given sufficient volume.



So, tell me how the NSA manages to listen, read all this information?
