Despite the emergence of instant messaging platforms, email is still the king of digital communication, particularly in the professional and business world. The number of email users globally is expected to reach 4.3 billion by the end of 2023, which accounts for more than half of the world’s population. Also, the total number of emails sent and received every day is forecasted to rise to 347.3 billion by 2023.
Probably because of its vast userbase, email is also a common cyberattack vector. For instance, some 65% of cybercriminal groups use phishing as their primary infection vector, and almost 60% of IT professionals view phishing as a top security threat.
