Customer delight is a crucial aspect of the marketing and selling process. Customer delight, contrary to popular belief is not only a post sale activity, but a pre sale one as well. Making the customer happy is the most important thing in the marketing process, because if the customer isn't happy, then business will greatly suffer. If the customer isn't happy, then he or she won't decide to purchase anything from your company, and will be less likely to even visit your website.
The three pillars of customer delight are innovation, communication, and education. Innovation offers a different aspect in the marketing than the normal status quo. Innovation offers the customer a reason that your product is a better product than other on the market. Communication offers the customer a sense of security. The more communication that you have with the customer the better, you can allow for more reassurance that way. Education allows for the customer to grow their knowledge about the product, industry, and your company as a whole, and will allow them to make better informed decisions.
