Driving 419 Jobs and £180K in Revenue by Re-engaging Customers with Delight
For service businesses built on repeat customers, growth often comes down to staying top of mind. But consistently engaging a large customer base without a dedicated team can be difficult.
For Dutchman Window & Cleaning, a company with nearly 70 years of history, that challenge became an opportunity.
By introducing Delight, the team found a scalable way to reconnect with dormant customers, smooth seasonal demand, and generate new work—without adding manual effort.
A Strong Reputation, but Limited Outreach
Founded in 1958, Dutchman Window & Cleaning serves residential and commercial customers, offering everything from standard cleaning to specialized high-rise rope access services.
With decades of brand recognition, the company has long relied on repeat business and referrals.
“We’re probably the most well-known company in our area,” said Ben Mitchell, Chief Operating Officer. “We’ve been able to rely on existing relationships for a long time.”
However, despite a database of approximately 9,000 customers, outreach was inconsistent and largely manual. At the same time, seasonal demand created fluctuations in workload.
“We don’t do heavy marketing,” Mitchell said. “But we wanted a way to stay in front of customers and smooth out some of that seasonality.”
Turning Customer Data into Demand
Dutchman Window & Cleaning saw an opportunity to activate the customer data they already had.
Delight analyses customer history to identify dormant contacts and automatically sends personalized outreach based on past services.
“It’s something you probably should already be doing,” Mitchell said. “We just didn’t have a set-and-forget way to do it.”
Implementation was straightforward, and the system quickly began working in the background, consistently reaching out to past customers without requiring manual effort.
From Reminders to Revenue
Rather than creating demand from scratch, Delight helps convert existing intent into action.
“What we see most is people who just aren’t thinking about it,” Mitchell said. “They get reminded, and then they reach out.”
That reminder-driven engagement has delivered clear results.
In just eight months, Delight-driven outreach generated:
- 419 jobs from automated emails
- £180,000+ in revenue
- 71% email open rate
“We’ll have customers respond directly to the emails,” Mitchell said. “That’s when you know it’s working.”
Even when customers do not engage immediately, consistent visibility reinforces brand recognition.
“Even if they don’t read it, they see our name, and that keeps us top of mind.”
Consistent Engagement Without Added Work
One of the biggest advantages for Dutchman Window & Cleaning is the ability to maintain ongoing customer engagement without adding operational overhead.
Delight sends emails at a controlled, optimized frequency, ensuring outreach remains consistent but not overwhelming.
“You can set it so it’s not obnoxious,” Mitchell said. “It just quietly does its job in the background.”
This approach allows the team to stay focused on operations while still benefiting from continuous outreach.
Expanding Growth Opportunities
Beyond re-engagement, the team is using Delight to introduce new services to existing customers, creating additional revenue opportunities within their base.
“Anytime we add a new service, we can immediately make that known to our customers,” Mitchell said.
With a large and loyal customer base, that ability to communicate quickly and consistently is a meaningful advantage.
A Smarter Way to Grow
For Mitchell, the value of Delight comes down to simplicity and impact.
“It’s already integrated and ready to go,” he said. “It doesn’t take much effort, and it’s smarter than a typical email platform because it’s using your real data.”
While no attribution is perfect, the results are clear in day-to-day operations.
“It fills a gap we know we had,” Mitchell said. “It’s helping us stay connected to customers in a way we weren’t before.”
For Dutchman Window & Cleaning, that connection is translating into measurable impact—more jobs, more revenue, and more value from the customers they already have.
