It is quite common for people to lump in marketing and communications into one thing. However, marketing communication is not the same thing. Instead, there are differences between the two that should be noted. Make sure you understand how the two differ from one another so that you can point yourself in the direction that you want to go.
Communications is the work of telling the story of the brand. Marketing is about doing the advertising of telling that story. That is the main way that they are different from one another. Both are necessary to create a message and to get it out to the broader public. You should make sure you are practicing both of these to help create the best kind of marketing campaign that you could ever imagine. When you can put that all together, you can get what you need out of the campaigns you are putting together.
Think all of this through and make sure you are looking at how both elements come together to create a better ad. There are people who are talented at communications and people who are good at marketing. That said, you should make sure you are getting people together who can do both of these things. Marketing is also something that you also need to think about. This is the best way to get the story you have created out to the world.
