Omnichannel marketing strategies put in place a chosen marketing strategy across many platforms. But, unlike the multi-channel promotional strategies, omnichannel marketing is not static.
Omnichannel marketing strategies unify. All the different channels update after the customer interacts with the brand. Multi-channel promotion is generally static, offering a set of preset marketing features.
Omnichannel is usually dynamic and changes often, depending on the client's actions. The result is a seamless end-to-end marketing and sales experience.
