Marketing communication involves sharing of meaningful data and concepts by the source and the receiver, about products and services. Marketing communication is carried out by markets through the promotion devices including advertising, publicity, salesmanship and sales promotion. There is also informal communication to speed up the coverage of marketing communication.

The successful communication takes place when a sender (source) sends a message and a receiver react to the message in a way that satisfies the sender. Both (sender and receiver) must have the same meaning of the message. Effective communication is equal to: acceptance of the message plus understanding plus acceptance plus action, which means decision to purchase.
