The NHS approached an agency partner to provide an SMS service to support its Stoptober smoking cessation campaign. Participants who texted a keyword would be added to a database to automatically receive up to 5 supportive messages per day for 28 days. Over 2.5 million messages were sent in 59 days from the So-Mo-Lo platform to participants, using a dedicated short code and high-volume platform to ensure quick, reliable delivery at scale.
