Why does my purpose-driven messaging feel preachy to customers?

Purpose messaging becomes preachy when it centers the brand's values over customer benefit. Effective mission-driven branding explains how your purpose serves their needs, not why they should care about your beliefs. The question isn't 'here's what we believe' but 'here's how what we believe makes your life better.' Nike's Kaepernick campaign worked because it aligned athlete identity with brand values.
