Email marketing is how businesses send promotional messages, newsletters, and offers directly to your inbox. When you sign up for a mailing list or create an account online, companies collect your email address and often other details about you—what you buy, what you click, where you live. Understanding how this system works helps you make choices about which lists to join, what information to share, and how to manage the messages you receive.
The articles here explain what happens to your data when you subscribe to emails, how companies track your behavior through those messages, and what privacy controls actually exist. You'll learn why some emails ask for so much information, what "unsubscribe" really does, and how to decide which trade-offs make sense for you.
