Permission marketing is a marketing strategy that focuses on obtaining the consent of potential customers before sending them promotional messages or advertisements. This approach involves building a relationship with consumers by providing them with valuable and relevant content, rather than bombarding them with unsolicited and intrusive marketing materials. By gaining permission from individuals to communicate with them, businesses can establish trust and credibility, leading to higher engagement and conversion rates. This type of marketing is often seen as a more ethical and effective way to reach and retain customers in the digital age.
