Answer:Direct Marketing
Explanation:
What Is Direct Marketing?
Direct marketing involves promoting a product by directly distributing it to potential customers.
It is referred to as direct marketing because customers are approached directly without using the middleman.
It doesn't depend on mass media advertising because sales are directly delivered through mails or emails.
There is usually a response link on the email which will tell the business of how many customers were responsive to the product. A response is a sign of a potential purchase.
