E-marketing is a process of planning and executing the conception, distribution, promotion, and pricing of products and services in a computerized, networked environment, such as the Internet and the World Wide Web, to facilitate exchanges and satisfy customer demands. It has two distinct advantages over traditional marketing. E-marketing provides customers with more convenience and more competitive prices, and it enables businesses to reduce operational costs.
What's the difference between them? One-off communications versus prolonged, email-based interactions. For example, email marketing tools are excellent for one-off communications. You can use these tools for the one time you'd like to send someone an automated email response when they join a subscriber list, on their birthday, or when you promote a new product. But marketing automation tools are better suited for prolonged, email-based interactions. For example, you can use marketing automation tools whenever you want to guide someone from a subscriber list to a product purchase. Or you can send thank you emails or send new product promotions—all without having to lift a finger after the workflow is designed.

Push marketing is a proactive technique that enables e-marketers to "push" their product/service information to Web visitors or shoppers without their requesting it. Banner advertising, pop-up advertising, e-mail promotion, and spamming belong to push marketing. For instance, e-marketers can rent designated space from Internet service providers such as America Online or MSN for their banner or pop-up ads. Using animated graphics, appealing messages, and links, e-marketers try to lure visitors to their sites to buy their products or services. Many Internet users, however, find such ads annoying and employ software that blocks pop-ups and banner ads. <
