The client, an auto repair shop, experienced a 5% loss in sales last year and sought to increase sales. Mspark targeted 15,000 households near the shop based on spending habits and demographics and mailed them an insert with service offers. This resulted in 13 redeemed coupons, a 3.65% return on investment, and a 2.3% increase in gross revenue for the client. The client was satisfied with the return and plans to continue working with Mspark.
