Siddhartha D. I think some marketing efforts can certainly feel that way when they aren't producing the desired results. Ideally mktg efforts/campaigns are being tracked to assess data to define if the strategy is a winner (keep), needs refinement (make adjustments), or needs to be discontinued (stop). If a mktg effort isn't producing after refinement and it's determined to not be a good ROI, then you may land on deciding to stop that mktg effort to invest resources in mktg campaigns that are producing or new mktg efforts you want to explore. I can't think of a good business reason to continue a mktg effort/campaign if you continue to not get much/anything out of it.
