What is an example of direct marketing?

Direct marketing involves communicating directly with consumers to promote products or services, typically through methods such as emails, letters, or advertisements that target individuals based on their needs or interests.

The reason that the email sent to an individual promoting a new book which is on sale is an example of direct marketing is that it is a targeted communication specifically aimed at a particular individual with the intent of encouraging a purchase. This method directly seeks to engage the recipient by presenting an offer and enticing them to take action, making it a clear example of direct marketing.

In contrast, the other options do not focus on a direct promotional approach tailored specifically to the recipient's interests in the same manner. For instance, the first option concerns transactional communication regarding an order and does not aim to promote a new product. The letter addressed to "the household" lacks personalization and is more of a general outreach rather than direct marketing. Lastly, the advertisement on a website is a broader marketing strategy that seeks to capture attention but does not establish a direct correspondence with an individual. Thus, it doesn't fit the definition of direct marketing as effectively as the email promoting the new book.
