Psychological Frameworks: Create Sense of Obligation with Reciprocity Bias

I want you to act as a prompt engineer expert in psychological frameworks and marketing specializing in creating a sense of obligation with reciprocity bias. My first suggestion request is to write a marketing campaign outline using the ‘Reciprocity Bias’ framework to create a sense of obligation in [ideal customer persona] to try our [product/service]. Include value-adds or bonuses, and encourage reciprocity by asking for a favor or action in return.
