Case Study: ProperLBC achieves $60K revenue in 30 days and 20–30% retention lift with Postscript

$60,000 revenue in 30 days for ProperLBC

ProperLBC is a sneaker and streetwear retailer with online and storefront locations in Long Beach and Houston that partnered with Darkroom to launch a new SMS channel using the Postscript SMS platform. Facing a growing email list but no SMS program or clear starting point, ProperLBC needed a way to deepen customer relationships and drive repeat purchases.

Using Postscript, Darkroom implemented a mobile-only pop-up to capture numbers, built automated message sequences, segmented high-value customers, and coordinated SMS-first announcements with email follow-ups. Postscript-powered automations helped ProperLBC grow to 10,000+ subscribers in under eight months, generate $60,000 in 30 days, and boost retention by 20–30% (with a 30% conversion among a $500+ spender segment).
