Closed Retainer Deals / Month
When we first met Bram, founder of an international SEO agency, he was super hungry and determined to turn on every acquisition channel possible to start scaling aggressively. The agency had a solid foundation — strong reputation, great service — but growth was relying too much on referrals and inbound. He wanted predictability.
He had already worked with a few cold email agencies before, but their approach was untransparent, the messaging felt off, and results never came close to expectations.
During onboarding, we followed the usual process -> set the expectations -> map the full strategy
He received a complete Notion file detailing every step of our process — from campaign architecture and messaging logic, to follow-up systems and deliverability methodology.
"It wasn't just a fancy dashboard. It was actual strategy — step by step. That gave me trust right away."
After warming up the infrastructure - we launched the first campaign
Launch, Learn, Iterate
"We were like, what is happening? This really works."
Cold Labs has been delivering a steady stream of qualified opportunities since launch — typically 100–150 positive replies a month, translating into 2–3 closed retainers every month. Each deal ranges between $2K–$5K/month, with contract durations from six to twelve months.
Campaigns are refined continuously. We A/B test messaging, rotate inbox infrastructure, and monitor deliverability daily. Any inbox with a health score below 97% is paused and replaced automatically to ensure flawless sending performance.
Bottom Line
In just six months:
2–3 new clients closed every month, all on 6–12 month retainers
$80K–$100K in revenue generated so far
ROI - through the roof
Long-term retainer clients replacing short-term project wins
"If you want a steady flow of daily leads based on the exact factors that matter to your business — go with Cold Labs. These guys don't run spammy campaigns. They think strategically, test, and deliver." – Bram, Founder of [Agency Name].
