Email spam refers to unsolicited or unwanted emails sent in bulk to a large number of recipients. These emails are usually sent for commercial purposes, such as promoting a product or service, or for fraudulent purposes, such as phishing scams or other types of online scams.
Email spam can also be used to spread malware or viruses, and it can be a nuisance to users who receive a large volume of unwanted emails. Many email providers have implemented spam filters to automatically detect and block these types of emails, but some spam messages may still slip through.
