David Lehnert, and his business partner, Chad Lemus, started Wyngman Agency in 2022. Within a short span of time, the duo managed to establish themselves as trusted lead gen partners in the industry.

They helped companies like Ponoko, idEngine, Innovade(.)io, etc. Their commitment to delivering results-driven campaigns and dedication to finding winning angles for clients makes them stand out in the market. For instance, in the case of Ponoko, Wyngman Agency helped them generate 18 sales opportunities in just 5 weeks. 

They’re clearly growing to be one of the most efficient lead-gen agencies in the B2B space. Here’s another achievement: Wyngman managed to bag a 21.43% response rate, which is huge in terms of industry standard.

Let’s get into more details of Wyngman Agency’s story and find out how Smartlead plays a significant role in their day-to-day efficiency.  

Who is Wyngman Agency?

The Wyngman Agency provides cold outreach services for startups and B2B companies. They assist clients in lead generation, finding winning campaign angles, and achieving successful outcomes.

People hire Wingman Agency for their four core strengths. 

  • Firstly, their exceptional copywriting skills ensure compelling and effective messaging. 
  • Secondly, their automation capabilities streamline workflows and enhance efficiency. 
  • Thirdly, their expertise in crafting unique selling propositions (USPs) helps clients stand out in competitive markets. 
  • Lastly, their proficiency in lead conversion ensures that leads generated through their outreach efforts are effectively nurtured and converted into customers.

All of these points make Wingman Agency a trusted partner for businesses seeking to optimize their outreach strategies and drive growth.

How It All Started?

David Lehnert and his business partner, Chad Lemus, initiated their entrepreneurial journey by founding Wyngman Agency. While Chad comes with 15+ years of sales experience, David brings his technical experience as a developer. 

It all started when David, who loves traveling, wanted to do something combining his technical knowledge and love for one-on-one communication. Together, they recognized a market niche—start-ups and complex B2B companies—that struggled with cold outreach. The commonly faced challenges included inefficient lead lists and ineffective cold email copy.    

They founded Wyngman Agency to make cold outreach easier for start-ups and B2B companies. Combining David's knowledge in automation with Chad's expertise as a sales coach, they aimed to deliver personalized, targeted outreach campaigns for clients with high deliverability rates. 

While exploring efficient tools for cold outreach, David discovered Smartlead. He chose Smartlead due to its superior API integrations, white label functionality, and ease of use, which aligned well with Wyngman Agency's need for streamlined workflows and targeted outreach campaigns to deliver exceptional results for their clients.

Challenges Faced

The Wyngman Agency encountered challenges with API integrations and the absence of whitelabel functionality when using previous tools for their outreach efforts. 

The previous tools they used lacked seamless integration capabilities with other tools in their workflow. This hindered their ability to automate processes and gather necessary data efficiently, ultimately impacting the effectiveness of their outreach campaigns. 

The absence of whitelabel functionality also posed problems when onboarding new clients who preferred to work within their own ecosystem rather than adopting new tools. This limitation hindered the agency's ability to provide a seamless experience for their clients and potentially affected client retention and satisfaction. 

These challenges prompted the Wyngman Agency to seek out a solution like Smartlead, which offered superior API integration capabilities and white label functionality, addressing their specific needs and enhancing their overall outreach strategy.

Key Factors Contributing to Success

Three key factors contributing to the success of the Wyngman Agency are:

Efficient Workflow Automation with Advanced API Integrations

Smartlead's API integration feature allows the Wyngman Agency to automate various aspects of their outreach process, saving time and resources. By seamlessly connecting Smartlead with other tools in their workflow, they can streamline data collection, lead management, and campaign tracking. 

This efficiency enables them to focus more on strategy and client communication, ultimately enhancing their effectiveness in generating leads and achieving results.

Enhanced Client Experience with Whitelabel Functionality

Smartlead's whitelabel functionality empowers the Wyngman Agency to provide a personalized and branded experience for their clients. They can maintain consistency in branding and user experience by offering seamless integration of Smartlead within their own ecosystem, fostering trust and loyalty among their client base. This feature helps in maintaining professionalism and building a sense of reliability, contributing to long-term client relationships.

Advanced Analytics and Tracking with Master Inbox

Smartlead's master inbox and analytics capabilities equip the Wyngman Agency with valuable insights into their outreach campaigns. With features such as customizable views and detailed reporting, they can track the performance of their campaigns, monitor response rates, and iterate on their strategies accordingly. 

This data-driven approach allows them to optimize their efforts, identify successful tactics, and continuously improve their outcomes, solidifying their position as leaders in the cold outreach space.

Looking Ahead for Success

Smartlead's strong API, unlimited warmups, master inbox, and whitelabel functionality help Wyngman Agency streamline its workflow. This allows them to focus on delivering great results for clients, establishing themselves as a trusted partner in the industry.

Moving forward, David and Chad are determined to push the boundaries of lead generation. Their collaboration with Smartlead is just a stepping stone to their future successful ventures.
