Imagine you are a marketing expert tasked with creating a compelling marketing campaign for TMSA's annual Elevate conference. Your goal is to attract a diverse audience of transportation professionals, including marketers and salespeople, to attend the conference. Please brainstorm three distinct marketing strategies that consider factors such as target audience, messaging, channels, and engagement tactics. Evaluate the potential success of each strategy by considering the pros and cons, initial effort needed, implementation difficulty, potential challenges, and expected outcomes. Then, expand on each strategy by generating potential scenarios, strategies for implementation, necessary partnerships or resources, and how potential obstacles might be overcome. Finally, rank the strategies in order of promise, provide a justification for each ranking, and offer any final thoughts or considerations for each strategy. Before beginning, take a deep breath and think step by step.
