The two numbers that justify the channel
A replacement system commonly runs several thousand dollars, and a maintenance membership holds a customer for years. Against customer values like that, mail budgets are rounding errors:
200 homes/month × $349 flat ≈ $1.75 per household reached, designed and mailed
One replacement job pays for a year or more of monthly neighborhood mail
The response bar is correspondingly low: on a 200-home monthly route, a single booked tune-up that later converts to a membership or replacement carries the quarter.
Who to mail
- The streets around every completed job.This is the neighbor effect, and it is the most celebrated play in home-services marketing: the neighbors watched your truck in the driveway for two days, so a card that lands the same week ("we just replaced a system on this street") converts context you already paid for. Saturation mail by carrier route is the mechanism; on StampSherpa you drag the circle over the job’s neighborhood and send.
- Your service list, by name. Every past customer without a maintenance membership gets a tune-up card in shoulder season. House lists respond at 5 to 9 percent in industry panels; nothing cold comes close.
- Aging-home neighborhoods. Systems fail at 12 to 18 years, so subdivisions built in waves fail in waves. Route-level demographics (median ages, household counts) help pick the ring; StampSherpa shows household counts per route as you drag.
Offers that book
The workhorse is the seasonal tune-up with a price and a deadline: "Tune up your A/C now and save $40 before July." It books because it is cheap to say yes to, and every tune-up is a foot in the door for the real economics (memberships and replacements). Strong variants: a second-opinion offer on replacement quotes, a "no cooling? seen today" emergency line for July, and a membership pitch framed as skipping the surge ("members jump the line in heat waves").
The seasonal calendar
- April-May: A/C tune-up push, pre-heat.
- June-August: emergency availability + replacement second opinions.
- September-October: furnace tune-up push, pre-cold.
- November-January: emergency heating + indoor air quality.
- February-March: membership drives and duct work, the quiet-season fill.
Track it like a service call
Every card carries a response mechanism: a scannable code that logs to a dashboard plus your real phone number. Count a three-week window per drop, hold rates to a 25-card floor, and attribute bookings by asking one intake question ("what got you to call?"). Judge the program on booked jobs per quarter against job value, never on week-one silence: campaigns with three or more touches lift response by as much as 50 percent in Lob’s research, and the neighbor who saw your card in May calls in July when the system dies.
A 90-day starter plan
- Month 1: saturation ring around your densest recent-job neighborhood with the seasonal tune-up offer; addressed cards to past customers without memberships.
- Month 2: second touch on the same ring, new design, same offer. Move the circle to the next job cluster too.
- Month 3:third touch with the deadline sharpened; read the dashboard (scans by day, calls booked) and pick next quarter’s rings from data.
The zero-effort version: paste your websiteand six cards design themselves in about a minute, tuned to your company’s look and offers. Drag the circle over a neighborhood and the month is handled from $349 per month.
