Final answer:
Email provides an inexpensive, rapid way of communicating with customers in writing worldwide.
Step-by-step explanation:
Email is the tool that provides an inexpensive, rapid means of written communication globally, largely due to advancements in internet technology that enables instantaneous messaging and information exchange. When looking at the alternatives for communication, such as travel or remote messaging, the latter is often much more feasible due to cost considerations. For instance, students from the United States may want to communicate with their peers in Australia and choosing to send a message over flying becomes the logical choice due to the high cost of airline tickets.
Furthermore, the rise of the internet and various social media platforms has significantly accelerated the process of globalization. With the advent of technologies that offer free Internet-based calling and video calling, businesses and individuals alike can communicate instantaneously across the globe without incurring substantial costs. This form of communication is especially beneficial for sharing various forms of information, an integral part of long-distance economic connections dealing with production and sales.
