What characterizes spam in the context of email communication?

Spam in the context of email communication is defined as unsolicited messages that are typically sent in bulk. These messages often serve as advertisements and are usually computer-generated, meaning they are dispatched automatically without individual targeting or personal relevance to the recipient. This mass distribution method focuses on reaching a large number of users, often leading to inbox clutter.

Personalized content for specific audiences represents a more tailored approach to communication, which contrasts with the generic nature of spam. Interactive communication implies engagement and back-and-forth interaction with recipients, while spam typically lacks this personal touch. Targeted marketing campaigns rely on user behavior data to customize messages for a specific audience, which is also contrary to the fundamental nature of spam, as it does not consider the preferences or past behaviors of the recipients. Thus, the characteristic that most accurately defines spam is the description of computer-generated unsolicited advertising messages.
