Hit the mailbox before homeowners shop. A focused February-to-April playbook for past customers and pool homeowner prospects.
Start FreePool homeowners decide who's opening the pool in February and March, before any pumps run. The companies that mail in those windows lock in past customers and pick up new ones. Mail in May, after schedules are set, and you're chasing customers who already booked someone else.
Spring Opening Recall: 3 waves February to early April
"Schedule your opening before the calendar fills." Photo of a recent opening, QR to a booking form. Past customers from last year only. Trust signal is "the people who serviced your pool last year."
"Skip the trips to the pool store. We open, service, and close. From [your price]." Mailed to homeowners with pools who aren't past customers. QR + Call Queue phone follow-up.
"Pump on year 8? Energy-efficient swap trims your energy bill over the season." Higher-margin upgrade offer to past customers whose equipment is aging. Late-season nudge for stragglers.
Wave timing comes pre-set; launch earlier in Sun Belt markets. Copy direction and call scripts come pre-configured.
Past customers exported from Skimmer, Pool Office Manager, or your CRM as a CSV or Excel file. Prospects from a homeowner data provider with the "swimming pool" filter for your service zips.
Postcards print and drop into USPS within 1–2 business days. QR scans are tracked as link clicks.
Pre-loaded scripts for opening, weekly-service signups, and equipment upgrade conversations. Staff log each outcome in PostKnock and book the opening in their own scheduler.
A typical pool company with 400 past customers and a 1,500-home prospect list (homes with pools). Here's the math on a 3-wave spring program:
40:1+ ROI on the first season alone, before equipment upgrades or fall closings.

See all Pool Services campaigns →February 15 in most of the US. Sun Belt markets (Florida, Arizona, Texas, southern California) should mail January 15–25 for early-March openings. The goal is to land before homeowners shop.
25–40% when you mail in February. Drops to 10–15% if you wait until April because most homeowners have already booked. Timing beats offer for past customers.
Most data providers (DataAxle, AccuData, ListSource) tag homes with pools using assessor data. Pull by zip with the "swimming pool" filter to get a clean list of in-ground pool homes. Above-ground pools are harder to identify and a smaller market.
"From [your price]/week" with a clear first-month offer outperforms "call for pricing" by 3–5x. Customers compare on price first; transparency earns the call.
No. "Pump on year 8? Energy-efficient swap trims your energy bill over the season" works without naming brands. You quote the actual brand on the call. Postcard real estate is precious; save the spec for the conversation.
Stop chasing customers who already booked someone else. Start the recall cadence that lands before they shop.
