How many emails are sent every day?

How many emails are sent every day?
about 360 billion
A person answering every email in a 120-message day at two minutes each would spend four hours on it before doing any other work.

Around 360 billion emails are sent each day, and well over half of them are spam — filters catch most of it, so the figure a user experiences bears no relation to the traffic. Business email is a minority of the volume but nearly all of the value. The average office worker receives roughly 120 emails a day and sends about 40. Despite thirty years of predictions that messaging apps would kill it, email volume grows a few percent a year.

How the figure is arrived at

Extrapolated from mailbox counts rather than counted. Take the number of active email accounts worldwide — around 4.5 billion — multiply by measured send and receive rates from a sample of corporate and consumer providers, and adjust for accounts that are dormant. Spam is measured separately at the network level by security vendors.
