Just email marketing

I am planning to self-publish a small vocabulary book that contains the most common words used in English , Headwords, GRE words. The book is written in a unique style and a proven teaching method. It is intended for beginners, intermediate and advanced students and learners. No such a book is available in any bookstore in my country. I am planning to lunch a marketing and advertising Campaign at a budget of around 10-12 thousands. I will market through newspapers, emails , faxes, book signing , direct sales to customers through phone, setting a selling points in major malls for promoting and direct selling of the book to customers.Do you think the idea of the book is successful? what do you think of the whole issue ? Any advice , comment? Should i proceed with my plan or just drop the whole matter?

I would lke to find out what is the key distinguising factor between a newsletter and a magazine.
