Case Study: 140 Sales Opportunities Per Day for Funded Startup

Case Study: 140 New Sales Opportunities PER DAY for Funded Startup, and Reaching Profitability in 3 Months

Let me show you how we partnered up with this funded startup, scaled it to 140 new sales opportunities per day, and got it to profitability all within 3 months of working with us.

By building a robust, sustainable outbound system that can practically scale up limitless, and that can predictably get the same results over and over again for years to come.

We define a 'Sales Opportunity' as a meeting-ready lead interested in your product or services.

Before they partnered with us:

Previous to our partnership, the company was sending mass email campaigns with an SMTP api like SendGrid. Although you can send mass email campaigns with this, it’s a poor method to use if you want to have high converting sustainable email outreach campaigns.

Due to this method they where running into these issues:

  • Emails would land in the spam folder
  • Too few sales opportunities
  • Sales opportunities would not convert to new clients
  • Domains & Inboxes would constantly land on blacklists
  • They were not profitable
  • No email scripts, angles and follow ups were tested
  • The data was a mess, and the sending infrastructure was fragile

Things were not looking good.

We took them on a partner.

We set out to built the most advanced system we had built so far, and which had to consist of the following criteria:

  • It needed to scale client acquisition to immense heights
  • Cost of Acquisitions needed to be lower compared to paid advertising
  • Emails need to always land in the inbox, and convert to sales opportunities
  • Sales opportunities had to actually convert into clients
  • Very consistent and predictable results were needed to get investors on board

Here’s how we did it:

Lead Sourcing

A large dataset containing emails, names and other contact information of prospects that matched the ICP (Ideal Client Profile) of our partner was acquired. 

Custom tools were used to verify the emails and other data of each prospect to only reach out to those that would actually be considered ideal prospects. 

Domain & Inbox Setup

We created a large web of several hundred email inboxes that would all route back to 1 master inbox, using a concept called ‘load balancing’.

Load balancing refers to the practice of spreading out the total email volume over a certain number of email inboxes. So that each email inbox only sends a handful of emails a day, while keeping the total volume very high.

By doing this we were able to send about 250.000 emails per month, with perfect deliverability (meaning we don't land in spam).

Testing & Optimization Strategy

At this scale, optimizing each part of the outreach campaign is crucial.

We continuously ran ab/n tests on email copywriting angles, scripts, follow up sequences, subject lines and CTA’s.

To prevent spamfilters to recognise the same email being sent over and over again, a method called ‘Spintax’ was implemented. 

We’ve coded in 3-4 alternative words for each word within the email script. When the code is ran, each email will be some combination of these words and will always be a unique email that has never been sent before.

Spam Monitoring

We closely monitored deliverability of each inbox on all major ESPs (Email Service Provider’s).

Meaning that the moment one of our inboxes was not landing in gmail, hotmail, outlook or other email platforms anymore, we were notified and could take that inbox out of our campaigns, and replace it by backups.

Data management / Insights

With handling so much data, things get messy very quick.

To be able to make the right decisions, we built a custom dashboard that tracked all relevant KPI’s in realtime.


With this setup, we were able to send out about 250.000 emails a month.

Out of those, we would on average convert 1.68% of those into new clients.

Thereby scaling our partners’ client acquisition to a massive 140 new clients per day, every day, even on weekends.

Our partner had to scale up their sales teams and their whole operations to accommodate this scale.

Training in-house team

After reaching profitability, we trained our partners’ team on how to operate our system in-house.

We handed all that we built, including SOPs and training on how to keep the results going, and potentially scale even further.
