Understanding e-Marketing
E- Marketing, also referred to as web marketing, online
marketing, or Internet Marketing, is the marketing  of products or
services over the Internet. E-Marketing is essentially part of marketing.
So let’s try to understand where it fits within the subject of marketing
The American Marketing Association (AMA) defines marketing
as follows:
Marketing is an organizational function and a set of processes
for creating, communicating and delivering value to customers and
for managing customer relationships in ways that benefit the
organization and its stakeholders.

managing customer relationships in ways that benefit the
organization and its stakeholders. As such an aspect, E-Marketing 
has its own approaches and tools that contribute to the achievement
of marketing goals and objectives.
