You see a gorgeous girl at a party and you say to her “Hi, I am rich, Marry me!” That is Direct Marketing.
If she walks up to you and says, “Hi, You are very rich, I want to marry you.” That is Brand Recognition.
If you call her the next day and say, “I am very rich, Marry me.” That is Telemarketing.
If she slaps your face when you say “Marry me”. That is Customer Feedback.
