Seeking Feedback: How Can This Presentation Improve Email Writing Skills?

Hi,

I have enclosed a presentation for my employees to help them improve their email writing skills. This file can be very helpful, especially if you are new to electronic business communication. I would appreciate valuable feedback from experienced professionals.

Crisp and basic information has been covered. Few areas of improvement:
Slide 1: Email Etiquette and not Etiquettes
Slide 2: Info graphics are difficult to read. It would be better to rewrite the content.
Slide 3: Anatomy of (an) Email
Slide 6: Some examples could have been added
Slide 12 & 13: The information could have been segregated into Dos and Don'ts
