Frederik Bussler and his team at Bussler & Co sent 38000 cold emails in October, 2023 using Smartlead. Out of which, they managed to bag 2,437 replies, which is around 19.45% reply rate. And these numbers are from their in-house campaigns only.Â
Mind blowing enough?
But there’s more. They’re not just good at booking meetings, they do it all in marketing. They increased a cybersecurity platform's DA by 600%. Another story: they helped an AI start-up to grow to $4.7 million from seed.Â
One of the primary factors behind their success is their lead generation tactics. As you can see the number, when it comes to generating leads, they don’t compromise with either quality or quantity.Â
Let’s look at the challenges faced by Bussler & Co and how they managed to overcome them. Â
Bussler & Co provides innovative and cost-effective enterprise-level marketing services with cutting-edge technology. It was founded by Frederik Bussler, a prodigy in his own right, on whom Forbes published an article when he was just 19. Led by him, their team comprises former OpenAI and HubSpot professionals.Â
They offer B2B lead generation cum sales services along with content and SEO, public relations, and social media management to drive growth and enhance brand visibility for businesses.

Bussler & Co is an all-in-one marketing solution. From lead generation to social media management, they do it all. Here’s a list of challenges they faced before using Smartlead:Â
Earlier they depended on Linkedin for lead generation efforts, which cost around $4,000 to $5,000 per month. They needed a more cost-effective solution.
Many clients, particularly VC-funded startups, lacked sufficient budgets and teams for extensive marketing campaigns. They demanded cost-effective marketing channels.
Before Frederik became a cold email expert, he relied on Gmail and Workspace to send outreach campaigns, instead of using a cold email tool. This led to high deliverability issues such as high spam rates and domain blocklisting, etc. They needed a tool that would allow adding spintags to diversify emails and avoid spam filters.
Their outreach campaigns consisted of sending bulk emails. To do that without getting blacklisted, Frederik and his team required a tool capable of warming up numerous mailboxes simultaneously as many as 80 mailboxes.Â
They also needed bulk mailbox uploading (via CSV) feature that could handle this process seamlessly.
Frederik and his team wanted a software with real-time replies, so that they could follow up instantly and increase the chances of conversion.
Smartlead addressed Bussler & Co's challenges by providing a comprehensive solution for their email infrastructure needs. Firstly, Smartlead's platform offered cost-effective lead generation capabilities, enabling them to generate leads efficiently without incurring the high costs associated with LinkedIn campaigns.Â
Secondly, Smartlead's features facilitated the management of large-scale email campaigns, allowing Bussler & Co to send 1000s of emails seamlessly. Its advanced features such as unlimited AI-warm-ups and bulk mailbox upload via CSV made bulk outreach possible without spending a fortune.Â
Smartlead also helped them tackle deliverability issues by enabling easy spintags and custom variables addition in mail sequences.Â
As sales is one of their primary services, Frederik and his team needed a platform that fetched real-time replies. Smartlead’s master inbox with real-time replies helped them follow up instantly and booked more meetings.
With Smartlead's user-friendly interface and bulk mailbox management capabilities, Bussler & Co successfully built a robust email infrastructure, overcoming their previous challenges and enabling them to conduct effective lead generation campaigns at scale.

Outbound has always been the fastest channel for scaling a company's revenue. Unlike inbound, it’s cost-effective and time-saving. Business organizations, especially the ones with smaller teams, can grow to new heights using outbound channels like cold emailing.
As you’ve read in this case study, Bussler & Co are booking as many as 72 meetings in a month through cold emailing. Not to forget, they’re helping many companies to reach a new level of success.Â
If you’re a lead generation agency or looking to scale your business, I would recommend trying Smartlead to send cold emails. With a good-quality lead list and killer copy, you can also increase your revenue more than 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.
