Dear Colleagues,

The three pillars of any sustainable development are environmental, social and economic (Chabowski et al. 2011). In sales and marketing, it is important to attract and retain the most valuable customers (Han et al., 2020). Successful organizations flourish for several reasons. However, the biggest reason for their success is the customer. For this reason, customer relations must become a major part of any organization's long-term plans (Lee et al., 2020). Over the last decade, the Internet has revolutionized how organizations engage with customers. At the same time, global development is now more threatened by unsustainable consumption and production than ever (United Nations Environment Programme, 2015).

Recently, researchers are increasingly taking the multidimensionality of the sustainability construct into account (Calderon-Monge et al., 2020; Catlin et al., 2017; Choi and Ng, 2011; Paço et al., 2020). However, the current literature does not examine the notion that it is essential for businesses to consider that different sustainability dimensions should coexist for a sustainable long-term business plan.

Most people and businesses want to live and make decisions to satisfy their present economic and social needs. Maintaining sustainable customer retention should be balanced with not compromising the environment. Most organizations recognize customer experience as a major competitive differentiator, and customer service plays a key role in defining that experience. Any perceptive business executive understands that, to retain customers, it pays to nurture customer relationships. A well-designed system can maintain positive relationships with customers, meeting their economical needs and, at the same time, the suitability of consumption as their social responsibility. This Special Issue addresses the issues related to customer relations, related to the three pillars of sustainability (environmental, social and economic).
