What is the definition of spam in the context of e-mail?

In the context of e-mail, spam is defined as unwanted e-mail messages, often sent in bulk, that typically have a commercial purpose. These messages flood inboxes and are generally not solicited by the recipient, meaning the recipient did not explicitly request or opt-in to receive them. Spam can range from advertisements for products and services to phishing attempts designed to capture personal information.

The emphasis on bulk sending highlights that spam messages are usually distributed to a large number of recipients, rather than being sent individually. This practice often aims to promote a product or service without consideration for the recipients' desires or interests, which is what classifies them as unwanted. Understanding the nature of spam is essential for recognizing the importance of e-mail filters and security measures to protect users from potential scams or unwanted communications.
