Case Study: Delta Sonic Car Wash Systems achieves 50,000+ text subscribers with SimpleTexting

How Delta Sonic Got More Than 50,000 Text Subscribers

Delta Sonic Car Wash Systems, which operates over 29 car wash, gas station, and convenience store locations across New York, Pennsylvania, and Illinois, needed a fast, reliable way to drive traffic during weather- and season-driven slow periods. They partnered with SimpleTexting to build a text marketing club and reach customers instantly via SMS.

Using SimpleTexting’s platform, Delta Sonic offered a free slushie or bottled water to opt-ins, implemented double opt-in, on-site signage, web forms, segmentation, and a steady cadence of 3–4 messages per month. The campaign drove a bump of nearly 20,000 subscribers from the promotion, grew the list to over 50,000 active subscribers who receive weekly messages, and produced measurable sales impact (one rainy-day blast generated 1,000+ interior cleanings), significantly improving retention and conversion.
