Which marketing strategy involves mailing a discount voucher to potential customers?

The strategy that involves mailing a discount voucher to potential customers falls under sales promotion. Sales promotions are marketing tactics specifically designed to encourage the purchase of a product or service through short-term incentives. By sending a discount voucher, the intention is to stimulate immediate action from potential customers, enticing them to make a purchase they might not have considered otherwise.

This method effectively engages customers by offering them a tangible benefit—cost savings—which can lead to increased sales. It differs from other marketing strategies like public relations, which focuses on managing a brand's public image and building relationships with various stakeholders. Similarly, while selling and direct marketing could involve outreach to potential customers, the specific act of mailing a discount voucher is more aligned with direct incentives tied to promotions rather than direct selling. Brand awareness aims to make consumers familiar with a brand and does not typically include direct monetary incentives like discount vouchers.
