New-Mover Postcards for Plumbers
There's a short window right after someone moves into a house when they're more open to trying a new plumber than they will ever be again. They don't have a go-to yet, they're already fixing up small things around the house, and they genuinely don't know how old that water heater in the garage is. Miss that window and they'll pick whoever shows up first the next time something leaks — probably found through a rushed search rather than a recommendation.
The window nobody else is mailing to
Most plumbing marketing is reactive: a pipe bursts, someone searches, and price and availability decide who gets the call. New-mover marketing is the opposite — it reaches people before anything is broken, while they're still forming an opinion of who they'd call if something did break. That's a fundamentally different, and easier, sale than competing for an emergency call against five other companies.
Where the list comes from
New-mover lists are typically built from public records tied to recent home purchases, refreshed regularly so you're mailing people in roughly their first one to three months in a home — recent enough that they're still in "getting settled" mode, but not so immediate that the card arrives before they've unpacked the kitchen. A tight radius around your actual service area matters more here than list size; a huge list of movers you can't reasonably dispatch to just wastes the mailing.
What the postcard should actually say
Welcome them to the neighborhood before you sell anything — a line acknowledging the move stands out from every other piece of mail that's purely transactional. Then get practical: mention that older homes often have plumbing quirks the new owner won't know about, and that a quick inspection can catch problems (an aging water heater, slow leaks, outdated shutoff valves) before they turn into a weekend emergency. Keep the offer simple and low-commitment — an introductory inspection or a modest first-service consideration reads as helpful, not pushy, to someone who just spent everything they had on a down payment.
Include your service area and hours clearly. New residents don't yet know who's local and who's a bigger regional outfit, so plainly stating "serving your neighborhood" carries more weight with them than it would with an existing customer.
Timing and frequency
Unlike a lot of seasonal campaigns, new-mover mail works year-round because people move year-round. The practical approach is to run it as a standing, recurring wave rather than a one-time push — mail is generated against your service area on a regular cadence (monthly is common) so every household that moves in gets reached within their first few months, without you having to remember to relaunch a campaign.
A single card is enough to introduce yourself, but a short reminder a few weeks later to the same household catches people who filed the first card away with good intentions and then forgot about it.
Pair the mailer with a call
If your workflow includes an optional follow-up call, new movers are a good use of it — a friendly call a couple of weeks after the postcard, offering to answer any questions about the house's plumbing, feels like genuine helpfulness rather than a sales pitch, especially to someone still learning their new home's quirks.
What to track
Because this is an ongoing, always-on campaign rather than a single event, tracking matters even more than usual — you want to know your cost per booked inspection over time, not just after one batch. A dedicated phone number or scheduling link for the new-mover wave lets you see which months and which neighborhoods are converting best, so you can adjust the radius or the offer without having to guess. Over several months of a standing wave, you'll also start to see how many of those inspections turn into repeat customers over the following year — which is really the point of reaching people before they have a plumber at all.
PostKnock keeps a new-mover wave running automatically against your service area, handles the postcard design and the reminder timing, and tracks the results, so this becomes a background campaign rather than something you have to remember to relaunch.
