SPAM consists of unsolicited/unwanted email messages, which are sent to a recipient against his/her will. SPAM most commonly includes bulk commercial email, which is sent to multiple email address for the purpose of advertising a product or service with a common subject and message body. SPAM doesn't always mean bulk email but anything that is objectionable to the recipient.
