Key Highlights

  • Achieved 2.6% reply and 62% positive reply rate in a 7,999-email campaign.
  • Every client booked at least 5 meetings with ideal prospects in month one.
  • Smartlead’s automation and warm-up saved 10–15 hours of manual effort daily.
  • Streamlined multi-channel outreach for diverse industries.
  • Noted for strong deliverability, scalable client management, and fast campaign execution.

Background

With four years in B2B lead generation—including two as a freelancer and two as the founder of GrowthSet, Rozana has honed an approach centered on multi-channel outreach (cold email, LinkedIn, and cold calling) for companies in industries like real estate, transportation, insurance, and tech. GrowthSet’s mission is to qualify leads, book meetings, and deliver clear ROI through targeted, data-driven campaigns.

Challenges

Email Deliverability and Infrastructure

Ensuring cold emails are sent from secondary domains, setting up high-quality warmup routines (preferring at least three weeks), and maintaining strong deliverability to avoid spam folders.

Sequencing and Follow-ups

Orchestrating timely, automated follow-ups across different time zones and optimizing sending windows—difficult and time-consuming when managed manually.

Scalability

Managing campaigns for multiple clients quickly became challenging, even with just 2–3 clients, highlighting the need for automation in outreach and email sequencing.

Smartlead as the Solution

Effective Warm-up

Smartlead’s warm-up system reliably mimics genuine conversation, warming both Google and Outlook inboxes, ensuring solid email deliverability and reputation.

Automated Sequencing

Makes it easy to automate multi-step follow-up flows based on time zone and reply windows, removing manual guesswork and timing issues.

“I had faced issues with sending emails at the right time based on the time zones, but Smartlead has helped me with this problem.”

Client Management Efficiency

Smartlead simplified high-volume client campaign management, reducing the need for a larger team and automating historically manual, repetitive tasks.

Integration and Analytics

Broad integrations and actionable reply/bounce metrics made it possible to closely monitor and optimize reply rates (targeting 3%+), bounce rates, and positive responses for each campaign.

Results

  • Consistent Meetings: All GrowthSet clients book at least 5 meetings with their ICP in the first month.
  • Case Highlight: For a campaign with 7,999 emails sent, GrowthSet achieved 55 replies (2.6% reply rate) and 34 positive replies (61.8% of replies resulted in a booking or meaningful engagement).
  • Time Savings: Automation with Smartlead saves several hours per day—without it, GrowthSet would require up to 10–15 additional staff to manage the same workload.
  • Deliverability Confidence: The warmup system's authenticity contributed significantly to consistently strong deliverability and reply rates.
“Our client case studies that we're doing, it has a pretty incredible reply rate. I'm positive that Smartlead also has a big role in influencing all that.”

Conclusion

By implementing Smartlead, GrowthSet transformed its B2B lead generation process—scaling multi-channel campaigns, boosting reply and positive response rates, and maintaining high deliverability—while keeping operations lean and delivering rapid ROI to clients across multiple industries.

Smartlead's combination of automation, unlimited inboxes, and easy campaign management has completely transformed how we run cold email campaigns.

Justin Chi

Founder, Cold Email Hackers

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

Sander Poolman

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.

Brigitta Ruha

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.

Daniel Greaves

Founder, FueltoFly

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

Harris Kenny

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.

Sergio Ocampo

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.

Bharatt Arorah

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.

Wesley Hoang

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.

Bruno Erckmam

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.

Eric Nowoslawski

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.

Ari Sohn

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.

Atishay Jain

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.

Matteo Fois

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.

Gabriel Martinez

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.

Maximilian Jendrall

CEO, Halfwarm

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

Maximilien Moriceau

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.

Omar Abdalla

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.

Preeti Malik

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.

Ethan Chamish

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.

David Sinclair Black

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.

Philipp Käming

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.

Aamir Bajwa

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'.

Ryan Bryden

Founder, Apex Ascension
