Data-driven marketing strategy delivers high-quality results for window installation advertiser<\/em><\/p>\n\n\n\n

\n\n\n\n

Background<\/h2>\n\n\n\n

A large window company specializing in replacement windows, doors and siding for homeowners partnered with Valpak to drive new window sales within multiple markets across the U.S.<\/p>\n\n\n\n

Both the client and Valpak’s sales team knew that a keen understanding of the window replacement industry \u2013 and of the client’s home improvement customers \u2013 would be vital to the program’s success. That meant establishing KPIs, program goals and a profile of the customers most likely to respond.<\/p>\n\n\n\n

Case study development<\/h2>\n\n\n\n

To begin, the window company sent in a sampling of its customer database, from which Valpak’s data analysts built a custom persona profile \u2013 identifying exactly who the ideal customer looked like (age, income, education, occupation, home value, presence of children, urbanization, socioeconomic rank and more).<\/p>\n\n\n\n

Once that profile existed, Valpak matched it to homeowner-occupied households within its footprint that shared the same characteristics, then narrowed further to the areas with the highest customer penetration and sales. Pairing the client’s customer data with Valpak’s demographic and household-level data \u2013 like age of home \u2013 was what made the test intelligent instead of a mass mailing.<\/p>\n\n\n\n

Marketing strategy<\/h2>\n\n\n\n

All parties agreed on a strategy of mailing 3 million homes across 6 major U.S. markets at a 3x frequency. Only homes inside the client’s serviceable footprint were targeted, and every home had to meet the established profile.<\/p>\n\n\n\n

Targeted households received a standard insert in their Valpak Blue Envelope with a quality windows offer (“Buy 2 Windows, Get 2 Free. Plus Pay Nothing for 2 Years”) and a call to action for a free quote. The promotion and the client’s business information were also featured on valpak.com for additional exposure.<\/p>\n\n\n\n

Results: 8-to-1 ROAS<\/h2>\n\n\n\n

Valpak and the window installation client collaborated through continued data sharing to track campaign performance. After the first two mailings alone, Valpak had generated nearly $365,000 in new window sales \u2013 a return of nearly 7 to 1 \u2013 with an average ticket 42% higher than the client’s target.<\/p>\n\n\n\n

What started as 3x mailings to 3 million homes grew to 6 million homes by the fourth mailing, with an expansion into 6 additional markets.<\/p>\n\n\n\n

After five mailings, the program had generated nearly $1.7 million in sales for an 8-to-1 return on ad spend. Average ticket stayed above goal, and the client’s 41% close ratio beat target.<\/p>\n\n\n\n

Why direct mail still works<\/h2>\n\n\n\n

Direct mail’s response-rate advantage has widened, not narrowed.<\/strong> The ANA\/DMA 2025 Response Rate Report puts the average direct mail response rate at 4.4% across all industries \u2013 5% to 9% on house lists \u2013 against a fraction of a percent for email. House-list direct mail also delivers the highest average ROI of any paid channel the report tracks, at 161%.<\/p>\n\n\n\n

Mail still gets opened and handled.<\/strong> Per the USPS Household Diary Study, 84% of consumers read direct mail the same day it arrives, and 96% of mail is handled by someone in the household \u2013 the physical presence that makes a targeted offer land differently than a scrollable ad.<\/p>\n\n\n\n

Window replacement projects are trending bigger, not smaller.<\/strong> Joyce Windows’ 2026 Cost Calculator data shows a median project size of 9 windows, with 48% of homeowners spec’ing 10 or more \u2013 a whole-home replacement pattern rather than a single-window fix. And the Home Improvement Research Institute’s window, skylight and patio door demand forecast points to continued replacement-driven growth through 2026, as aging housing stock keeps this category resilient even as new construction cools.<\/p>\n\n\n\n

Together, that means the same playbook this client used \u2013 a tight customer persona, footprint-matched targeting, and a strong offer delivered by mail \u2013 is arguably a better bet today than it was when this program ran: response rates on well-targeted lists are holding, ticket sizes are growing, and the industry’s replacement demand isn’t going anywhere.<\/p>\n\n\n\n

Conclusion<\/h2>\n\n\n\n

The results of the mailings and the program’s growth into new markets confirm that campaigns built on data are the ones that deliver the strongest returns for window replacement companies, and across industries.<\/p>\n\n\n\n

FAQ <\/h2>\n\n\n\n

What ROI can a window replacement company expect from direct mail advertising?<\/strong><\/p>\n\n\n\n

In this case study, a national window replacement company reached an 8-to-1 return on ad spend after five mailings to a data-matched audience, following a 7-to-1 return after the first two. Industry-wide, the ANA\/DMA 2025 Response Rate Report puts average direct mail ROI on house lists at 161% \u2013 among the highest of any paid channel it tracks.<\/p>\n\n\n\n

How does Valpak target homeowners likely to buy replacement windows?<\/strong><\/p>\n\n\n\n

Valpak builds a custom persona from the advertiser’s own customer data (age, income, home value, presence of children, urbanization and more), then matches that profile against homeowner households in its footprint using demographic and household-level data such as age of home \u2013 targeting only the households most likely to convert.<\/p>\n\n\n\n

Is direct mail still effective for home improvement advertising in 2026?<\/strong><\/p>\n\n\n\n

Yes. Direct mail’s average response rate (4.4%, per ANA\/DMA) remains far above digital email benchmarks, and 84% of consumers read direct mail the same day it arrives (USPS Household Diary Study). Combined with rising average project sizes in the window replacement category, direct mail continues to perform well for high-ticket, considered home improvement purchases.<\/p>\n\n\n\n
