Turns out the majority of the spam hitting your inbox is originating in the U.S. Cybersecurity company VIPRE’s Email Threat Trends Report for Q1 2025 found that 57 percent of all spam emails sent in the first quarter of this year came from the U.S. The report looked at 1.45 billion emails, analyzing the geolocation of the origin IP address in the email header.
There’s no single cause as to why the U.S. is apparently a hotbed for spam emails, but one contributing factor is the scale of data center infrastructure. With so many data centers spread across the country, there are numerous entry points from which spam emails can spread. This also makes it difficult to enforce spam regulations.
Of all the spam emails analyzed in the report, 67 percent were found to be malicious, meaning they contained phishing or malware links. PDF attachments were the most popular source of delivering malicious links, followed by SVG attachments. The manufacturing sector is cyber criminals’ current favorite target, followed by a tie between retail and finance.
