Launching a new product, an email campaign achieved a strong open rate (40%) but a low click-through rate (3%), highlighting subject line effectiveness but content misalignment. Optimizing CTAs and featuring user testimonials boosted CTR to 8%, with corresponding conversion lift. Simultaneously, social media engagement metrics rose, signaling growing audience interest.
