An established home improvement brand was emailing its list, but the channel produced almost no attributed sales.
The Client and the Problem
A high-ticket home improvement brand selling windows, doors, siding, and roofing through in-home consultations already had an email list and was sending campaigns. Between January and August 2025, those sends produced almost no attributed sales. Seven months in the prior year had no attributed sales, and most of that year’s attributed value came from one product launch rather than a repeatable program.
1. Reach the List, Then Segment It
The program first reached the full list, then measured results across past buyers, quoted-but-not-closed leads, unreached leads, non-openers, and long-inactive contacts. Past buyers generated the strongest sales value per email, so later campaigns put more weight on that audience.
Campaign decisions began with audience-level results
2. Build a Monthly Rhythm and Add SMS
Starting in 2026, the team planned one offer campaign each month and sequenced messages by audience. SMS joined the program in March. Campaign timing accounted for the 30-to-45-day sales cycle, so performance was measured through the period when deals continued to close.
Email and SMS were measured through appointments and closed deals
3. Test, Learn, and Apply the Results
From June 2026, the program tested message format, angle, cadence, and copy mechanics. Each result informed later campaigns. Copy was tailored to the audience: past buyers responded to shorter, benefit-first messages, while quoted-but-not-closed leads responded to fuller, trust-led copy.
The next campaign reflected what the previous one taught
The Results
For September 2025 through August 2026 compared with September 2024 through August 2025:
| Metric | Before | After | Change |
|---|---|---|---|
| Attributed closed sales value | Prior-year baseline | First program year | 7.7x |
| Booked appointments | Prior-year baseline | First program year | 17.8x |
| Lead-to-appointment rate | 46.9% | 75.6% | +28.7 percentage points |
| Appointment-to-close rate | 40.0% | 58.2% | +18.2 percentage points |
Every month in the program year produced attributed sales. Seven of the 12 months in the prior year did not.
Key Takeaway
An existing list becomes a measurable sales channel when campaigns are segmented, planned around the buying cycle, and judged by appointments and closed sales. Here, the team used results from each audience and campaign to shape the next one.
If your email program is active but its contribution to sales is unclear, what happens between the first response and a closed sale?
