This Venn diagram sample depicts the relationship marketing.
"Relationship marketing was first defined as a form of marketing developed from direct response marketing campaigns which emphasizes customer retention and satisfaction, rather than a dominant focus on sales transactions. As a practice, relationship marketing differs from other forms of marketing in that it recognizes the long term value of customer relationships and extends communication beyond intrusive advertising and sales promotional messages. With the growth of the internet and mobile platforms, relationship marketing has continued to evolve and move forward as technology opens more collaborative and social communication channels. This includes tools for managing relationships with customers that goes beyond simple demographic and customer service data. Relationship marketing extends to include inbound marketing efforts, (a combination of search optimization and strategic content), PR, social media and application development."
