E-mail’s place in the marketing mix

I completly agree with this strategies because email today is the best way to communicate well and sale more in Hotel Industrie.
In maketing Mix we have the product, price,place ,promotion.
So how to spread quick informations without using some others ways who are so much expensive and you are not sure that people hat you tring to convaince have seen it. Every body have email address and no need to wait for postmen or some feedback who takes too much times.
The best way is to uses email and it's can be more effective if it is come with TV campains ; why that?
Because today we received to much emails and the things we delete immediatly without pay attention.
For hotellers that is brilliant strategies, you have quick response and you can easily have an idea about how you can sales effectivly your product for who, how much and where.
