Permission marketing is a term popularized by Seth Godin (but found earlier) used in marketing in general and e-marketing specifically. The undesirable opposite of permission marketing is interruption marketing. Marketers obtain permission before advancing to the next step in the purchasing process. For example, they ask permission to send email newsletters to prospective customers.
