Integrated marketing communication (IMC) is a cross-functional process for creating and nourishing profitable customer relationships. IMC strategically controls and influences all brand messages sent to stakeholders through any communication channel. The goal is to encourage purposeful dialogue and drive brand value.
There are four main sources of brand messages - planned messages from marketing activities, unplanned external messages, product messages from design/performance/pricing, and service messages from customer interactions. IMC aims to align all these messages to ensure consistent meaning and manage customer relationships.
