Retention through relevant automation
Large Car Wash Chain
InboundAV built targeted email and SMS automations to engage subscribers, reduce churn, and support membership upgrades.



The summary
The client needed a more proactive way to identify at-risk unlimited members, engage them before churn, and create a clearer upgrade path for limited members. The program transformed behavioral signals into timely, personalized communication across email and SMS.

About Large Car Wash Chain
This large exterior car-wash chain is one of the fastest-growing operators in the United States and operates more than 160 locations across Arizona, California, Colorado, Texas, and Utah. Its unlimited-membership model depends on sustained engagement long after the initial signup.
The challenge
When the company approached InboundAV, its unlimited-membership attrition rate averaged 10%. The team identified a clear pattern: members who had not visited a location for two weeks were at high risk of churning. At the same time, thousands of limited members in the database had not yet been given a relevant path to upgrade.
- Industry:
- Car Wash
- Company size:
- Large market (100+ employees)
- Locations:
- AZ, CA, CO, TX, and UT
- Use cases:
- Engagement, churn reduction, SMS
The solution
InboundAV built a retention program around behavioral segmentation. Email and SMS automations welcomed new members, re-engaged inactive subscribers before the two-week threshold, acknowledged visits, and nurtured limited members toward unlimited plans. Each message was designed to be relevant to the member’s actual status and activity.
All technologies used
- Marketing automation
- SMS
- Customer retention
The results
In the first three months, attrition dropped by 1.5 percentage points, representing roughly 1,500 members retained each month compared with the previous quarter. Limited-to-unlimited conversion reached 51%, and the program created a repeatable foundation for ongoing retention work.
