My Understanding of e-Marketing 1

Upon taking the e-marketing course, I need to make sense of the term "e-marketing"- so the following few posts are about "my understanding of e-marketing"



#1: how many ways to write to mean the same ?

On the back of my mind, it has been always telling me (someday) to track down how many ways to write e-marketing. Just altering the term "e" already makes a set of variety:

e-marketing
eMarketing
Emarketing
Internet marketing
i-marketing
Online marketing
Web marketing
web-marketing
and...Integrated e-marketing/e-Marketing/eMarketing etc.

Note: digital marketing does not precisely mean "internet" marketing. It not only uses internet but also includes devices that does not have internet such as mobile phones, SMS
