Co-Marketing is a strategic collaboration between two companies to create and execute joint marketing campaigns, allowing them to reach a broader audience and share promotional efforts. This partnership often includes co-branded content, shared advertising expenses, and mutual lead generation efforts. CRM systems track co-marketing campaigns by managing shared customer data, analyzing campaign effectiveness, and automating joint outreach. Co-marketing is commonly used in B2B partnerships, e-commerce collaborations, and influencer-brand relationships to expand audience reach, boost credibility, and maximize marketing ROI.
