Did you know that email marketing can drive 50% more sales than other lead generation methods? Yet, many marketers struggle to fully tap into this potential. In fact, while most marketers are keenly aware of their lead generation numbers, a surprising 12% admit they don’t even know how many leads they’re pulling in.
This calls for a more organized approach towards lead generation that goes beyond a simple spray and pray method.
Maximilian Jendrall, an entrepreneur and a lead generation expert based in Berlin, Germany, understood these challenges all too well.
With a rapidly growing agency that initially focused on German companies, Max quickly expanded to serve international clients. His mission was clear: to master the art of email outreach and drive consistent, measurable results for his clients.
However, as his business grew, so did the complexities. That's where Smartlead came into play, transforming the way Max's agency approached email marketing and lead generation.

Maximilian Jendrall, known as Max, is an operator and entrepreneur with a deep passion for building profitable, data-driven, and self-sustainable businesses. As the Founder and CEO of both Halfwarm ((known as Halbwarm in Germany) and Inbrox, Max has dedicated his career to optimizing business operations and scaling sales with precision. Halfwarm serves as a comprehensive sales operations partner, offering infrastructure, data, and expert consulting to ensure seamless scaling.
Meanwhile, Inbrox specializes in Ops-Engineering as a Service, focusing on constructing business-driven data pipelines, dashboards, and digitizing processes to drive efficiency and growth. Max’s expertise lies in combining data with strategy to build ventures that not only thrive but also sustain long-term success.
Halfwarm started with a simple yet powerful mission: to leverage cold email outreach to generate leads for German companies.
The success of this model spurred the agency to take on international clients, broadening its scope and reach. As the business evolved, Max didn't just stop at lead generation. He expanded into the tech space, creating a full-service offering that included lead aggregation, closing deals, and partnering with other companies to streamline fulfillment.
This approach positioned his agency as a growth partner for clients, handling everything from lead generation to final conversions.

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.
