What Are Compromised Computers?
In the context of
email marketing, compromised computers refer to systems that have been infiltrated by malicious actors. These systems are often used to send out spam or malicious emails without the owner's knowledge. Compromised computers can be part of a larger network of infected devices known as a
botnet.
Once a computer is compromised, it can be controlled remotely by cybercriminals to carry out various illicit activities, including sending out unwanted
marketing emails.

Legal Issues: Sending unsolicited emails can lead to legal repercussions under laws such as the
CAN-SPAM Act.
