Spam messages accounted for 45.37 percent of e-mail traffic in December 2021. During the most recently measured period, Russia generated the largest share of unsolicited spam e-mails with 24.77 percent of global spam volume. Despite its ubiquity, the global e-mail spam rate has actually been decreasing: the average daily spam volume in September 2021 worldwide was 88.88 billion, down from 282.93 billion in July 2021.
Spam e-mail It is almost impossible to think about e-mail without considering the issue of spam. In 2021, 319.6 billion e-mails were sent and received on a daily basis. This includes billions of promotional e-mails sent by marketers every day. Whilst many e-mail users believe such content belongs in their spam folder, marketing e-mails are generally harmless, if annoying to the user. In 2018, the spam placement rate of commercial e-mails had declined to nine percent, down from 14 percent in 2017.
Malicious spam Not all spam are benign promotional e-mails though. A significant portion of spam messages are of a more malicious nature, aiming to damage or hijack user systems. The most common variants of malicious spam worldwide include trojans, spyware, and ransomware.
