One thing about my business, I don't sell templates. I only sell REAL content. I believe that template is only to give you the general overview of direction but not how_to do it. That's why I highly not recommended you choose to download or purchase marketing templates because I have seen them i personally think it won't help you much. Let me share you a recent story about template.
The classical marketing plan would follow the following scheme: Declaring the mission: this is the planning stage when we establish the organizational orientations and intentions, thus providing a sense of direction. In most cases, this is a general presentation of the company's intentions and almost has a philosophic character.
