Case Study: Rex Specs achieves 116x ROI and boosts customer education with Postscript Conversational SMS

How Rex Specs uses Postscript and Conversational SMS to drive 100x ROI

Rex Specs, a maker of performance-driven gear for active dogs (best known for their dog goggles), faced a customer-service–heavy product with frequent questions about fit and training, plus internal hesitation about adopting a new channel. They partnered with Postscript to test Conversational SMS and automations as a way to educate customers after purchase, reduce returns, and provide quick two-way support.

Using Postscript’s SMS platform — automations (the TRAIN flow of five texts over 10 days), Responses for two‑way conversations, segmentation, and optimized Welcome Flows — Rex Specs reduced support friction and increased lifetime value while running high-performing campaigns. The program delivered massive ROI and measurable impact: averaging over 100x ROI (116x reported), $8.40–$8.54 EPM, 11–19% conversion rates, and a Bark Week campaign that achieved 64.8% CTR and 11.2% conversion; working with a dedicated Postscript CSM helped scale these results.
