Think of a major online retailer like Amazon.com that sells tens of thousands of different products but has no physical stores. Customers receive notices about sales through their email instead of their post office box. Shoppers can get more information about a product than a whole army of sales staff could offer. Amazon provides all of these services at a fraction of the operating cost most retailers face. The entire business model is based on cloud marketing; using the tools of the internet to connect with customers.Communication between marketers has improved. Online tools make it easy for colleagues to access, share and distribute information amongst each other. Using new applications, marketing duties can be outsourced for huge cost savings. For example, rather than hiring an in-house graphic designer, marketers can find a low cost freelancer online. The internet is both a place to do marketing and a tool for doing marketing.
