How Onestop Agency is Onboarding Five High-Ticket Clients a Month

Most agencies are throwing money at ads or blasting the same tired outreach templates to massive lists, hoping something sticks.

Not Onestopagency.

Instead of playing the volume game, they focused on precision, and it worked. In just 30 days, they booked seven qualified meetings through cold email alone. Five of those turned into high-ticket clients.

No ad spend. No overhyped tools. Just a clear process, clean data, and emails that actually get replies.

In this case study, we’re breaking down what they did differently, what wasn’t working before, and how switching to Manyreach helped them scale cold outreach without breaking the bank or their domain.

“Manyreach gave us the freedom to scale cold outreach without worrying about cost or deliverability. It just works.”

What is Onestopagency

Onestopagency is a growing lead generation agency that helps businesses book more sales calls through cold email and paid ads. Their focus is on creating lean, high-performing outbound systems that deliver results without bloated budgets.

Who They Target & Their Core Value Proposition

At the time of this case study, Onestop Agency is primarily working with real estate agents, brokers, and team leads based in the United States. 

Their ICP looks like this:

• Real estate agents, brokers, and team leads
• Active in markets like New York, California, Texas, and Florida
• Working in the mid- to high-ticket property space
• Demonstrating recent online activity or listings

Their core value proposition is cold email outreach. They help real estate professionals and experts generate high-quality leads in a consistent and cost-effective manner. 

Where does cold email fit in their growth playbook?

Cold email plays a dual role in OneStopAgency’s growth strategy. 

First, it’s their primary client acquisition channel, they use highly targeted cold outreach to connect with real estate professionals who fit their ICP. 

Second, it's the main service they deliver: once a client comes on board, OneStopAgency builds and manages cold email campaigns on their behalf to generate qualified leads and book meetings. This two-tiered approach makes cold email both a growth engine for the agency and a core value driver for their clients.

The Challenges Faced by Onestop Agency in the Early Days

Like many emerging lead generation agencies, OneStopAgency encountered several foundational challenges during its early growth phase. According to founder Dharmendra, these setbacks ultimately provided valuable learning opportunities.

1. Writing emails that didn’t convert

Initially, their cold email outreach was ineffective. Emails were often over 200 words long, lacking a clear structure, a strong hook, or a focused call to action. The team had not yet developed a clear understanding of best practices, such as keeping messages concise, conversational, and actionable, which impacted response rates.

2. Expensive subscriptions

Sustaining the cost of essential tools was another challenge. Monthly subscriptions for cold email platforms strained their limited budget, especially during the agency’s initial phase when cash flow was inconsistent. This limited their ability to scale outreach reliably.

3. Difficulty identifying a profitable niche

Finding the right market to serve proved to be a significant hurdle. The agency initially targeted broad categories such as online coaches and wellness professionals, segments that were highly competitive and often had limited marketing budgets. 

Over time, they pivoted to the real estate sector, focusing on agents and brokers operating in high-ticket markets. This shift enabled them to align their services with a niche that valued lead generation and had the resources to invest in it.

How OneStop Agency Solved Those Challenges

Instead of chasing volume, OneStopAgency built a lean, efficient system focused on high-quality prospects and real results. Here's how they tackled their early hurdles:

1. They Scrapped Data from Google Maps and LinkedIn

Dharmendra shared during the interview:

“I don’t believe that you need a long list of 10000 contacts to build your business. No, you only need a highly-targeted, deeply-researched lead list to expand your agency. You also don’t need 100s of lukewarm leads. You need genuinely interested people to respond.”

To ensure every contact on their list was relevant, OneStopAgency ditched generic databases in favor of highly-targeted scraping.

• Google Maps: They pulled business details using real estate-related keywords and zip codes, focusing on high-value or fast-growing areas. This included agency names, addresses, contact info, reviews, and websites.
  
  
• LinkedIn with Sales Navigator: They filtered by industry ("Real Estate"), roles ("Realtor", "Broker", "Team Lead"), and target specific geographies (city, state, zip code). They prioritized people recently active on LinkedIn and avoided saturated brokerage teams.

You can also customize your profile with years of experience and job title. 

This approach gave them warm, localized leads who were decision-makers, not random contacts.

2. They Built a Clean, Verified Email Pipeline

After identifying the right leads, they used GrowMeOrganic to:

• Extract email addresses from LinkedIn profiles.
• Prioritize business emails first, and fall back to personal only when necessary.
• Save hours of manual prospecting.

Every list was passed through an email verification step with Reoon verifier before any campaign went out—this ensured high deliverability and reduced bounce rates.

3. Personalization That Goes Beyond First Name

OneStopAgency knew that “Hi {{first name}}” alone doesn’t make people reply.

• They used variables within spintags to dynamically personalize with {{city name}}, {{company name}}, and other local context.
  
  
• They A/B tested subject lines and greetings consistently before deciding one.
  
  
• Their belief is that the smallest detail, such as referencing a zip code or a recent listing, can drive outsized replies.
  

4. Cold Email Copy That Converts

They followed a sharp, repeatable writing system:

• Subject Lines: Short, 6–7 words max. One favorite: “Hi {{first name}}, thought?”
  
  
• Frameworks Used:
  
  
  • Humor: For disarming intros.
    
    
  • FOMO: To position scarcity or missed opportunities.
    
    
  • Value-first: With clear, immediate benefits to the recipient.

Every email was kept concise, conversational, and ended with a single clear CTA.

Dharmendra made his cold emails stand out from the clutter by adding a low-pressure CTA and a Loom video. 

5. A Cost-Effective, Scalable Tech Stack

Instead of piling on expensive SaaS tools, they built a lightweight but powerful stack:

• Sales Navigator for precision prospecting.
  
  
• GrowMeOrganic for scraping and email extraction.
  
  
• Manyreach for cold outreach allows them to run affordable, automated, and deliverability-friendly campaigns without breaking the bank.

This eliminated their earlier cost bottleneck and gave them the flexibility to scale without worrying about ballooning subscription fees.

How Manyreach Helped Onestop Agency Scale Outreach

Switching to Manyreach turned out to be a game-changer for OneStopAgency.

1. Affordable and Scalable Sending

Before Manyreach, tool subscriptions were a major cost bottleneck. The cold email tools they tried offered base plans around $40 with only 50000 to 6000 email credits per month. So, when Manyreach’s Lifetime deal came along, he grabbed the offer.  

This slowed down campaigns and increased overhead. With Manyreach, they were able to:

• Send emails from multiple inboxes affordably
• Increase email volume without worrying about subscriptions or sudden pricing jumps
• Avoid overpaying for features they didn’t need

The switch allowed them to run multiple campaigns in parallel while keeping monthly costs predictable and manageable.

2. Built-in Inbox Warmup

Deliverability was a recurring concern, especially with new domains. Manyreach’s built-in inbox warmup and its effective warmup pool helped maintain sender reputation and kept emails out of spam folders, without needing a separate warmup tool.

This automated warmup allowed them to:

• Ramp up new inboxes safely
• Improve open and reply rates
• Eliminate the hassle of managing warmup tools separately
  

3. Cleaner, Safer Campaign Execution

Manyreach’s deliverability-first approach, with features like domain rotation, aligned perfectly with Onestop's quality-over-quantity philosophy. With verified leads and small, high-signal lists, the tool ensured emails reached inboxes, not junk folders.

It helped them maintain:

• Higher open rates (up to 65%)
  
  
• Better reply rates (2–3%)
  
  
• Consistent domain health across campaigns

4. Integrated with Their Stack Seamlessly

Manyreach fit right into the tool stack they had already built:

• Sales Navigator for prospecting
  ‍
  
• GrowMeOrganic for email discovery
  ‍
  
• Reoon for verification
  ‍
• Loom for small videos to pitch or show the solution to the pain points
  
  
• Manyreach for warmup and campaign sending
  
  

This tight integration made it easier to manage campaigns without switching tools or workflows.

5. Results After Switching

After shifting to Manyreach, OneStopAgency saw measurable improvements:

• Reply rates rose to 2–3%, up from less than 1% in earlier campaigns
  
  
• Open rates hit 65–70%, driven by clean lists and strong subject lines
  
  
• More consistent booked meetings each week
  
  
• Zero deliverability issues across 30+ campaigns

As Dharmendra put it:

“Manyreach gave us the freedom to scale cold outreach without worrying about cost or deliverability. It just works.”

Final Thoughts

If there’s one takeaway from this story, it’s this:

You don’t need to send 10,000 emails a week. You don’t need to blow your budget on ad spend. You definitely don’t need another complicated tool stack.

What you do need is what Onestopagency built:

• A small but accurate lead list
  
  
• Emails that feel human and helpful
  
  
• A setup that keeps your inbox (and budget) healthy
  
  
• A tool like Manyreach that lets you scale without stress

Their results weren’t about luck. They came from showing up with the right message, to the right people, in the right way. And now, they’re helping other real estate pros do the same.

This playbook works, and now you’ve got it.
