Initially a content-sharing website, Alex Vacca and Michel Lieben expanded ColdIQ on customers’ demand. They began their journey by making extensive content on sales tools targeting small business teams. Gradually, they began helping their customers with tool implementation and outbound strategies.Â
Now, in 2024, ColdIQ is a trusted name with hundreds of businesses relying on them for information and outbound-related help. Not to forget, Alex Vacca and Michel Lieben have established themselves as thought leaders on LinkedIn, enjoying a huge following.
Let’s find out how Alex Vacca and Michel Lieben managed to reach such successful heights.Â
Cold IQ is a lead generation agency that caters to B2B companies, helping them with tool implementation and outbound campaigns. They audit their clients’ existing outbound campaigns, design automated workflows, build new campaigns, and scale the winning ones.Â
Michel Lieben started ColdIQ with the vision of addressing a gap in the market for comparing sales tools effectively. He observed the limitations of existing platforms like G2, which favored established tools with more reviews and visibility.Â
Initially, they conceptualized ColdIQ, recognizing the need for a platform that could showcase newer, potentially better-suited tools for smaller companies. Before founding ColdIQ, Michel Lieben had firsthand experience with the difficulties of manual cold email outreach. He saw the inefficiencies and limitations of these processes and recognized the untapped potential for automation.Â
As they launched the ColdIQ website, they initially focused on content sharing and improving their SEO to attract visitors. However, as they gained traction, they noticed a growing demand from clients for more than just information—they wanted help implementing and managing sales tools, and even assistance with outbound marketing efforts.Â
This client feedback pushed Michel and his partner Alex Vacca to expand ColdIQ's services, transforming it into a full-fledged agency. This expansion allowed them not only to provide valuable content on sales tools but also offer services related to tool implementation and outbound campaigns.
Their journey reflects a combination of identifying market needs, leveraging personal expertise, and adapting to evolving client demands. Their collective efforts turned ColdIQ into a comprehensive platform and service provider for sales and marketing solutions.

ColdIQ's Ideal Customer Profile (ICP) includes diverse industries such as PropTech, agencies, and SaaS companies, primarily in the US and Europe. They come with a wide range of issues. Here are the most common challenges that the ColdIQ duo and their clients faced:Â
Earlier, the process of creating effective cold email campaigns they followed was manual and labor-intensive. They usually hired someone to launch personalized email campaigns, who would manually check profiles and customize one-liners accordingly. The process of sending email campaigns manually was time-consuming and lacked scalability.
Most of ColdIQ’s customers approached them because of poor engagement in their outreach campaigns. They came with low open and reply rates, ranging from 20-25% for open rates and as low as 1-2% for reply rates.
Earlier, Michel Lieben struggled with their clients due to the lack of automation in their cold emailing processes. Manual tasks such as data research, personalization, and follow-ups were time-consuming, limiting efficiency and scalability in their client campaigns.
Before using Smartlead, email management was an issue. As a lead gen agency, they handled multiple clients at a time. Without a master inbox in previously used tools, they found it challenging to monitor, track, and respond to leads.Â

Outbound channels, such as cold emailing, have consistently proven to be the most efficient method for rapidly increasing a company's revenue. Unlike inbound strategies, outbound approaches are both cost-effective and time-efficient. This makes them particularly advantageous for small teams looking to achieve significant growth and expand their business operations.
As you’ve read in this case study, ColdIQ is helping many B2B companies reach new levels in terms of business goals. They’re helping their clients achieve as high as 26.11% positive response rate. Not to forget, they’re educating many companies about sales tools and implementing the right ones for their business.Â
For lead generation agencies or those aiming to expand their business, I highly recommend SmartLead for cold email outreach. With a high-quality lead list and compelling copywriting, you have the potential to boost your revenue by over 100%, just like SalesAutomation.Systems.Â

Founder, Cold Email Hackers

We have about 15 companies and we use Smartlead for all of them.

Founder, DutchSave Media

One of the things I love about using Smartlead is the deliverability feature. If they landed in the bounce or spam folders, we could resolve this quickly.

Co-Founder, Growth Today

I want to continue to use Smartlead to make operations more seamless - the plan is to bring more clients here and build more SOPs.

Founder, FueltoFly

Smartlead listens to the agencies and customers and builds according to what people want, that has really made things easier for us.

Founder, OutboundSync

We build an infrastructure product, and OutboundSync communicates with Smartlead itself. I love the webhook and API. They're really well done and keep getting better.

Founder, Axoleads

With SmartDelivery, you can put all of that in the hands of the tool. It ensures your emails land in inboxes, and by running a simple test, you can see if you're hitting the mark.

Founder, Claygen
Deliverability is the cornerstone of cold email outreach. You could have the best email copy in the world, but if no one is seeing it, it's useless. I really love the feature where you can actually give client accesses to your clients.

Co-Founder, Cymate

I do not want to switch to another software. Pick a solution you trust, stick with it, and keep refining your copy.

CMO, Avalanche Capital

Managing large volumes of emails through multiple inboxes used to be a logistical nightmare. With Smartlead, the process is seamless. We book thousands of discovery calls through cold emails. These campaigns are generating leads at a scale we never thought possible.

Founder, Growth Engine X

We came for the unlimited inboxes, and we stayed for the API. 1.5M cold emails/month, 7,767+ inboxes managed.

Head of Community & Ecosystem, TxtCart

You cannot replace having 10,000 touches with potential clients. When you have that much distribution and reach, you really start to see incredible results. The simplicity of Smartlead made all the difference. It doesn't require you to be a technical wizard.

Founder, Hyperke

Smartlead has been a game-changer for us. It increased our appointment volume, improved ease of use, and offered valuable features. 80% increase in appointments/month, peak of 276 appointments in a single month.

Founder, Kinetyca

Smartlead has been our cold email backbone from day one. The platform evolves constantly, keeping pace with how deliverability and personalization need to work today. 21% overall reply rate, $175K in 4 months for multiple B2B clients.

Founder, Reachflow

Smartlead is centered around deliverability and constantly evolving. Their API is not like any other platform. Smartlead covers all our needs. The focus on core features like deliverability and API integration is unmatched.

CEO, Halfwarm

Our approach to crafting conversational emails led to reply rates that many of my peers thought were unattainable.

Co-Founder, letstrike

We've grown on zero capital, zero marketing, purely cold emailing - and that's the story we love to tell. The best approach is no approach if you can't handle domain meltdown. The second best is something like Smartlead that's built from the ground up for deliverability at scale.

Founder, Fenixtal

Smartlead's white-labeling and automation let us punch above our weight. The 12M euros sales potential? That's what happens when you combine human creativity with Smartlead's precision.

Co-Founder, Digital Creativs

Nine out of 10. Ninety percent of our clients are on Smartlead unless they come in with an existing setup. That's the default.

Co-Founder, BuildingReach

At the end of the day, you have to take a bet on one tool or another. It was a no-brainer taking that bet on Smartlead. We had to even turn down the volume of our marketing campaigns - Smartlead was capable of driving more volume than our sales team was able to fulfill.

Founder & MD, Prospectiv

Since starting the business in January of this year, we've already generated $200K in sales exclusively from cold email. Smartlead has been central to our operations and has exceeded our expectations.

Founder, Growthlynk

There's so much stuff built on top of it. I would be dead if I had to rebuild it with another tool. I can manage hundreds of senders easily. I can send hundreds of thousands of emails.

Founder, Corebits

The platform's HubSpot integration, real-time Slack updates, and advanced campaign customization have been game changers for our business and our clients'.

Founder, Apex Ascension

From day one, we've never used anything else.
