Spam refers to unsolicited or unwanted messages that are sent to a large number of recipients. While spam is most commonly associated with email, it can also appear through text messages, social media platforms, online forums, and other communication channels.
Many spam messages are simply advertisements, but others may attempt to collect personal information, distribute malware, or trick users into clicking harmful links.
Spam exists because sending large volumes of messages is relatively inexpensive, and even a small response rate can make these campaigns profitable for attackers and marketers.
Modern email providers and security systems work hard to filter spam, but unwanted messages still occasionally reach users’ inboxes.
