Case Study: Car Wash Group doubles customer contacts and boosts unlimited wash enrollment with Adentro

Car Wash Group - Customer Case Study

Car Wash Group, a five-location car wash operator in Tennessee, needed a simple way to grow its customer contact list to promote its unlimited car wash program. Capturing emails during quick express visits (often under five minutes) across mixed express and full-service formats was a challenge, so they selected Adentro’s smart WiFi platform to centralize contact collection and marketing.

Adentro installed Open-Mesh access points for outdoor coverage, provided WiFi decals to prompt guests to connect, and set up automated Smart Emails to engage customers after visits. The program quickly increased contact capture — roughly 1,400 new contacts in 30 days (about 45/week), with express sites averaging high daily signups — and delivered measurable impact, including up to a 41% Walk-Through Rate on top campaigns, higher unlimited-membership signups, increased gift card sales, and valuable customer feedback.
