What is a key characteristic of spam?

A key characteristic of spam is that it refers to unwanted email typically sent in bulk. This unsolicited communication often includes advertisements, promotional content, or fraudulent schemes, and it is commonly disseminated to many recipients at once without their consent. Spam can clutter email inboxes, making it difficult for users to locate important messages.

Unlike malware, which is designed to harm or exploit systems, spam's primary aspect revolves around the volume and nature of the unsolicited content shared. It does not typically install software or restrict access to networks; rather, it promotes unwanted products or services, which may include phishing attempts designed to deceive users. Understanding this aspect of spam helps individuals and organizations implement effective email filtering measures to enhance cybersecurity and improve productivity by reducing irrelevant communications.
