unsolicited bulk E-mail (UBE)

Unsolicited Bulk Emails (UBE) are unsolicited or unsolicited emails, usually referred to as spam. The word bulk refers to mass mailings.

In the case of unsolicited e-mails, a distinction is made between bulk e-mails and unsolicited commercial e-mails( UCE). The latter have unsolicited advertising content and a commercial purpose.

Both spam concepts are based on e-mail addresses that are captured by search robots or traded by dubious mail brokers.
