Unsolicited bulk e-mail are referred to as e-mail spam or just spam. These e-mail are sent to a large number of recipients and often contain advertising. Recipients are selected at random without any existing business relationship or giving consent to the sender.
You can receive spam e-mail that are not addressed to you, but to another recipient. The actual recipients of e-mail are not necessarily visible in the recipient line. This is the case if your address was entered in the Blind Carbon Copy (BCC) field. If that is the case, your e-mail address is not displayed. Bulk e-mail senders, generally senders of unsolicited advertising e-mail, often use this feature by entering only a pseudo-address in the e-mail. The e-mail is actually sent to hundreds of recipients.
There is a special form of spam called phishing. A phishing e-mail is a fake e-mail from a company or authority asking you to click a link and log in with your account data. The link takes you to a website, which is also fake, and any data you enter there is recorded by the attacker. If you receive a phishing e-mail and want to inform us, use the mail.com contact form for reporting phishing pages.
