Direct mail advertising for plumbers in the Knoxville metro.
Plumbers are the archetypal direct-mail small business: a $250 average ticket, urgent customer need, and homeowners who keep a trusted plumber's card on the fridge for years. The math on a Banjo Tech Standard slot ($300, ~3,000 homes) is the simplest in the catalog — one drain clear, one slab leak, one water heater replacement pays for the entire card run.
Why this works for plumbing companies
Plumbing is close to a platonic direct-mail category. Homeowners don't shop for a plumber — they look one up the moment something starts leaking, and they trust a physical artifact on the fridge more than a Google ad they've never seen before. A shared postcard that arrived four weeks ago and has been sitting on the kitchen counter beats a midnight Yelp search nine times out of ten.
The typical economics we see: a Knoxville-area plumbing company buys a Standard slot for $300. The card reaches ~3,000 verified homes. Over the card's ~6-week shelf life (that's how long a sturdy glossy tends to linger on a counter or fridge), the advertiser sees 15–40 scans of the QR code, 4–12 phone calls, and 2–6 billable jobs. Average plumbing ticket is ~$250 for a service call and $600+ for installs. Break-even is usually 1–2 calls.
What works on a plumbing postcard: a clean offer (e.g., "$25 off any drain", "flat-rate $89 diagnostic"), a 24-hour emergency phone number, a photo of your truck or your plumber, and QR code pointing to a direct booking or call page. Don't waste the slot on a pretty logo — make the phone number and the offer the biggest things on the card.
Category exclusivity matters a lot here. Knoxville has ~180 licensed plumbing companies; on a Banjo Tech card you're the only plumber. That's worth more than the $300 by itself.
