Automated direct mail campaigns drive 10x+ ROAS in the first 30 days of pilot.

United Comfort Group, a private equity-backed, multi-brand HVAC, and plumbing services portfolio, partnered with LettrLabs to modernize its direct mail across its brands.
Instead of relying on traditional zip-code mailers, UCG used LettrLabs to launch automated, data-driven direct mail campaigns triggered by real customer activity inside ServiceTitan.
The result: faster execution, clearer attribution, and strong early revenue performance.
Within approximately 30 days of mail delivery, UCG saw:
Attributed Revenue
Campaign Spend
ROAS across active campaigns
ROAS on top-performing campaigns
UCG wanted to prove performance and scale quickly, so these results were measured early in the attribution window, with additional revenue expected as campaigns mature over the typical 90-day attribution period.
Before LettrLabs, UCG’s direct mail strategy looked like many traditional home services programs:
Manually select zip codes
Manually send broad monthly mailers
Wait for results
Rely on manual reporting and matchbacks
The traditional printed mail campaigns produced about 4x ROAS, but the team lacked the visibility, automation, and speed needed to confidently scale direct mail across multiple brands.
UCG needed a direct mail channel that worked more like digital marketing: automated, trackable, measurable, and easier to optimize.
LettrLabs helped UCG launch a performance-focused direct mail playbook built around highly personalized, automated radius mailers.
Instead of blanketing entire zip codes, UCG mailed nearby homeowners after high-value jobs were completed in the area.
This allowed UCG to:
Target homes around proven demand
Launch campaigns based on real job activity
Track conversions and revenue directly
Compare campaign performance across brands and markets
Scale winning plays without rebuilding campaigns from scratch
The initial strategy focused on broad, high-impact campaigns rather than over-segmenting too early. This gave UCG a fast path to meaningful data, early wins, and expansion.
LettrLabs connected directly with ServiceTitan, allowing mail campaigns to trigger from customer and job data automatically.
That meant less manual list building, fewer operational delays, and a more scalable way to launch campaigns across multiple brands.
Unlike traditional direct mail programs that rely on delayed matchbacks and spreadsheets, LettrLabs gave UCG visibility into performance as results came in.
The team could see:
Mail spend
Conversions
Revenue
Estimated revenue
ROAS by campaign and market
This made direct mail easier to measure, evaluate, and defend internally.
LettrLabs combines automation with the feel of true 1:1 outreach. Each mailer is designed to look and read as if it were written specifically for the recipient—cutting through the noise of traditional print.
Handwritten messaging that stands out from standard marketing mail
Personalized with real data triggers (location, recent service activity, timing)
Higher engagement and response rates vs. generic bulk mailers
Seamlessly automated at scale, without sacrificing a personal touch
The result: direct mail that feels human, performs like digital, and converts like a high-intent channel.
UCG moved quickly from kickoff to execution.
Campaigns were live and mailers were in production in under two weeks, allowing the team to validate performance without a long implementation cycle.
Once the initial campaigns proved successful, UCG began expanding the program across additional brands.
The team is now evaluating additional plays, including:
Expanded radius targeting
Second-touch postcard follow-ups
New mover campaigns
Retargeting campaigns
Customer suppression and segmentation strategies
For UCG, LettrLabs helped shift direct mail from a static print tactic into a measurable growth channel.
The difference was not just the mail piece itself. It was the combination of automation, attribution, targeting, and speed.
With early campaigns generating approximately 10x ROAS, UCG now has a repeatable framework for scaling direct mail across its portfolio. They’ve automated their processes while improving their ROAS from 4x to 10x.
