Although we marketers sometimes use "omnichannel" and "multichannel" interchangeably, the words refer to different marketing strategies and result in different customer experiences.
• A multichannel marketing approach refers to a brand’s efforts to interact with customers across multiple platforms and channels. It focuses on growing customer engagement across those various channels.
• An omnichannel marketing approach, on the other hand, eclipses multichannel. Omnichannel marketing helps you promote stronger, lasting relationships with customers because they’re able to have a consistent brand experience no matter what device they use, when they use it, or where in their journey they are.
