About SalesLeadGen

SalesLeadGen is a London-based outbound agency, established in 2015, that provides a B2B Lead Generation service helping clients obtain outbound leads for the top of their sales pipeline through automated email and social media outreach campaigns.

The outbound agency world revolves around performing top-of-the-funnel activities such as list building, sending emails, and follow-ups to cold prospects to generate leads.

For SalesLeadGen, to scale their operations, they needed to automate this entire process in order to boost lead generation for their clients and expand their own business along the way.


SalesLeadGen sources email IDs from the social web and stores them in Google Sheets. Those contacts are then fed into an email tool to run personalized email outreach campaigns at scale. Then, based on activity data such as email opens, clicks, and replies, prospects who show interest are imported as warm leads into their Hubspot CRM.

SalesLeadGen realized that to make this process more productive and efficient, and to minimize time wastage, they needed to automate each step of the way so they could focus on high-value activities that helped in closing more deals.

Therefore, they were in the market looking for a tool that had the exact features that would successfully dovetail with their process and optimize it.

This tool needed to:

  1. Auto-import contacts from Google Sheets
  2. Run personalized cold email campaigns on auto-pilot
  3. Optimize outreach performance through split testing
  4. Get an in-depth analysis of outreach performance
  5. Automatically create leads in Hubspot CRM based on engagement activities

Nick Gilbert, the Managing Director and Co-founder of SalesLeadGen, had therefore explored several sales automation tools in his quest to find the best fit for SalesLeadGen’s requirements.

That was until he came across Klenty.

Klenty offered powerful features that eliminated most of their manual work and delivered end-to-end automation.

From automating the import of contacts from Google Sheets, and running personalized email campaigns to automatically creating deals in Hubspot, Klenty succeeded in taking any manual work out of the equation, thereby unlocking massive productivity gains for SalesLeadGen and their clients.

The Klenty Difference

Import prospects with one-click

SalesLeadGen was able to auto-import data from Google Sheets directly into Klenty due to Klenty’s strong integration with Google Sheets. With zero manual interference, leads were pushed into personalized email campaigns.

Run personalized campaigns at scale on autopilot

Klenty’s “Custom Fields” feature allowed SalesLeadGen to create dynamic fields, which helped power their outreach with personalization.o personalized email campaigns.

Experiment and optimize outreach

Once campaigns were up and running, Nick needed to test the emails to optimize their outreach performance and show the different results to their clients. That was where Klenty’s A/B testing feature proved clutch, as SalesLeadGen was able to execute split testing using a single interface — eliminating the irritation of using multiple cadences and then laboriously examining each to arrive at the results.

‘’Split testing is an important feature for any outbound marketing agency because you have to demonstrate to your clients that you are following a methodology that allows for some initial market testing, and then through a process of iteration, will deliver continually improving results for them in term of opens, clicks and therefore Marketing Qualified Leads.”.

Automated CRM workflows

Klenty’s native integration with Hubspot ensured that prospect engagement data like email opens, link clicks, and replies could be detected and synced automatically with the client’s Hubspot CRM through ‘Triggers and Actions’ in Klenty.

Through this Advanced CRM Workflow, the clients could work towards closing the deals with warm leads right from their CRM without juggling between the email tool and Hubspot.

Thus, the Klenty-Hubspot integration led to 2 major benefits:

  • SalesLeadGen's clients were instantly aware of the status of their leads at any given time by simply logging into Hubspot.
  • With warm leads in the CRM, clients could immediately work on guiding them further down the sales funnel without worrying about the otherwise time-consuming process of manually entering lead information into Hubspot.

”The Klenty-Hubspot integration was another critical feature for us, as our goal is to create a completely automated prospecting workflow for each client. We push contacts from the SalesLeadgen data platform into Klenty, and as Klenty emails these prospects, the contacts sync automatically into Hubspot, so the client then has a full audit trail of all communications within their CRM.”
