Case Study: Subway achieves better loyalty, personalisation and revenue growth with Merkle

Subway drives $100M+ incremental revenue with Merkle in 12 days

Subway faced a challenge with its loyalty program, which was supported by multiple technology providers. This setup limited its ability to personalize customer communications and access engagement tools, resulting in inflexibility, long lead times, and high costs for the business.

Acting as consultants, Merkle assessed Subway's maturity across key areas and conducted extensive surveys and interviews. This process led to the creation of a global business case and roadmap. The outcomes included a significantly improved first-party data strategy that drove over $100 million in incremental revenue, higher loyalty program engagement, and improved customer satisfaction metrics through a best-in-class omnichannel journey.
