When it comes to setting up a marketing campaign strategy, the #1 objective is to be efficient. It's not just important to have the campaign implemented at the right time, but rather to do the right thing that will lead to positive results.
Since I have been in Marketing, several new channels have become available and when they do, they are the new, shiny object that everyone is attracted to. Some people go as far to say you need no other marketing channels but the new one. I strongly disagree and believe you need all the channels to make a good, efficient marketing campaign that leads to a foundational strategy.
