What is Unwanted or junk email?

Unwanted or junk email, commonly referred to as spam, is unsolicited and often irrelevant messages sent to a large number of recipients, typically for advertising purposes. These emails can clutter inboxes, pose security risks, and sometimes contain malicious content or phishing attempts. Spam can be filtered by email providers, but it remains a persistent issue for users. Effective spam filters help manage and reduce the amount of junk email received.
