Their Story
Representing best-known auto brands
DCH Motors is one of the largest automotive service groups in Hong Kong. DCH’s services include sales, rentals, leasing, maintenance, repairs and accessories for some of the world’s best-known automotive brands.
Their Goal
Centralized marketing and customer service
The company’s leadership observed that customers often browsed car sales after normal business hours, at times when sales personnel were unavailable to respond to questions immediately. When new customers were acquired through promotional activities and transferred to the sales team, their information was often lost in the process, making it difficult for the sales team to help them find the right vehicle or service, and for the marketing team to effectively monitor the results of its efforts. DCH Motors was seeking a centralized, customer-focused solution to these challenges.

“The effectiveness of sending messages in WhatsApp is impressive, as we saw open rates of up to 80% and click-through rates of up to 10%. We were really impressed with WhatsApp Business Platform’s interactive capabilities, which allowed us to capture customer preferences and provide tailored recommendations that helped streamline our sales efforts. ”
