Why postcards work for plumbers
Plumbing is the textbook direct-mail trade. The decision is made under stress at the moment of failure. That moment is usually a weeknight, usually without a prepared vendor, and usually won by whoever the homeowner can find in under sixty seconds. A postcard pinned to the fridge at the right moment wins that race against Google every time.
Seasonality compounds the effect. Late October through January spikes when first-freeze events destroy water heaters and split outdoor spigots. Late February through early April spikes as homeowners discover the damage. Drop a postcard two to three weeks before each wave and the card is still in the kitchen when the wave hits. Category exclusivity closes the loop — no other plumber is on that fridge competing for the same call.
