This email is an example of informal digital media. The quote, "for whopping 45% off the regular price" tells us the grammar is incorrect and the word "awesome" tells us that this email sounds very basic, and awesome is not at all the way to describe a deal for a company. A correct example would be:
Hi Chris,
