40+ Gmail Statistics to Know in 2021

Back on April 1st, 2004, Gmail first went live. Due to the launch’s odd timing and the fact that it offered considerably more storage than its rivals, the tech world thought it was an elaborate April Fool’s joke.

Let’s take a look at some of the most pertinent Gmail statistics that you need to know.
