It's difficult (for me) to answer this without first getting a good idea of what you mean by "the campaign." If you're talking about an "advertising campaign," It would be like an "advertising strategy" in the sense that this is not "the thing" which you're showing to the customer. "The campaign" is "the sales plan," or perhaps "the
execution or
implementation of the plan." You don't reveal to the customer your plan or strategy for suckering him out of his money.
Re "showing off," if you're truly proud of something you don't mind telling someone that you would like to show it off, especially if it's a physical thing. But in some cases you might choose to beware that "showing off" is sometimes considered bad style, or overly ostentatious. 
But, yes, properly showing off a product to a prospective customer would certainly include doing so in an interesting and appealing way.
