Nordstrom has successfully increased store sales by leveraging Twilio's Mass Message (MMS) service, allowing their employees to send personalized messages with product images to customers via text messaging. The use of MMS has shown higher engagement rates compared to SMS and email campaigns, resulting in a drastic increase in retail sales for the company. By providing customers with a more interactive experience, Nordstrom's salespeople can share recommendations and timely reminders, giving customers control over their shopping experience. This approach is expected to be expanded to include additional uses of MMS, such as streamlining internal logistics.
