What is the term for a marketing strategy conducted through postal mail?

Direct-response marketing refers to a strategy where marketers directly communicate with potential customers through various means, including postal mail, with the aim of eliciting an immediate response. This approach often includes promotional materials or offers designed to encourage the recipient to take action, such as making a purchase or signing up for more information. In the context of using postal mail, direct-response marketing leverages the personal touch of mail to engage recipients and prompt them to respond directly, which is a core aspect of this marketing method.

On the other hand, options like indirect marketing typically involve broader, less targeted advertising that does not seek immediate interaction or response. A referral program focuses on leveraging existing customers to gain new ones, while agency marketing refers to the promotional efforts undertaken by insurance agencies themselves, which may encompass a variety of methods beyond just direct outreach through postal mail. Therefore, the definition of direct-response marketing aligns perfectly with the postal mail strategy described in the question.
