Email and SMS campaigns for a auto repair shop
The list sitting in your shop management system is the cheapest source of work you will ever have, and most shops never touch it. Every car that came through has a mileage interval, a set of declined repairs, and an inspection date. Campaigns built on those three book bays at a cost per repair order no ad channel can match. Email runs a fraction of a cent per send. Texts run a few cents.
The sequences worth building are specific, not seasonal blasts. Mileage reminders from the last service. Declined work from the last digital inspection, with the photo attached. State inspection dates where your state requires them. AC in the first warm week, batteries in the first cold one.
The mistake is texting a list that never opted in. Get written consent at the counter, honor stops immediately, and keep the record. The rules here are not optional and the penalties are real.
