How we helped a lighting company generate $310K in 90 days with a cold outreach system

From walk-ins to automated outbound without hiring a single rep.

The challenge

For over 20 years, this Cambodian lighting company relied on traditional sales: word-of-mouth, walk-in customers, and local referrals. It worked — until it didn’t.

As competition grew and regional expansion became a priority, they faced a new problem:

How do we scale sales without hiring an entire team?

They didn’t have in-house marketing, no sales ops team, and limited digital infrastructure.

Cold outreach felt risky, but they knew it was the next logical move.

The solution

We built a fully automated cold email outreach system that handled everything from research to reply logging without touching a line of code.

Here’s what the system included:

• 3 dedicated domains with professional mailboxes to maximize deliverability
• Email authentication (SPF, DKIM, DMARC) set up for all domains
• AI-based lead enrichment that auto-generated personalized icebreakers for every lead
• A centralized lead tracker in Google Sheets, complete with research notes and status updates
• Two multi-step cold email campaigns sent via Instantly
• A backend system that tied it all together — 100% automated

The results

In just three months:

• $310,000 in revenue generated
• 6,800+ emails sent
• 350+ qualified leads
• Reply rates of 10.9% and 14.1% across two campaigns
• 162% increase in quarterly sales
• 20+ hours saved per week by removing manual research and writing

This system didn’t just outperform industry benchmarks.

It replaced the need for multiple hires, allowing the founder to stay lean while scaling.

What the client said

We were skeptical about automation after 20+ years of manual sales, but took the leap with Nimbflow. Their systems bring us steady leads weekly and got us $310,000+ in new deals since the start of 2025. It’s hard to imagine moving forward without them now.
