list broking

List broking is the trade in mailing lists. It is an address trade used in marketing and direct advertising.

Every single e-mail address represents a potential contact and thus a value for the advertising industry and for agencies. That is why these addresses are actively traded by list brokers.

In purely legal terms, the e-mail addresses may only be used for e-mails or other online advertising measures after an opt-in by the consumer, which indicates consent to receive advertising contacts.
