Introduction

Growth Today, co-founded by Brigitta Ruha, is a fast-growing B2B agency specializing in helping scaling companies build repeatable and scalable outbound systems. 

Focusing on delivering qualified leads for B2B SaaS companies with $1M+ ARR, Growth Today provides end-to-end outbound management and one-time outbound/enrichment setups. Their selling point is that their outbound system feels human and is unique.

As the head of growth, Brigitta sought a reliable cold email tool to help streamline operations, overcome time constraints, and generate a predictable and scalable pipeline. 

After testing several cold email solutions, Growth Today chose Smartlead to manage its email infrastructure and outbound operations. Here’s how Smartlead transformed their business.

Business Context and Cold Email Needs

Growth Today’s mission is to help scaling B2B SaaS companies create predictable and scalable pipelines of qualified leads. 

Their ideal customers include founders and VPs of Sales at SaaS companies with 50-1000 employees and a minimum of $1M ARR. Growth Today’s services include fully managed outbound campaigns and one-time outbound/enrichment system setups.

While cold emailing remained a core acquisition strategy for Growth Today, Brigitta’s previous tools had several limitations, including:

  • Difficulty scaling outbound channels.
  • Managing large volumes of email infrastructure.
  • Reliance on resource-heavy, manual processes.
  • Avoiding spam filters while maintaining email deliverability.

Cold email marketing offers an effective solution for building scalable Go-to-Market (GTM) motions. However, Growth Today needed a tool to test strategies programmatically, build predictable outbound systems, and deliver repeatable results without resource overload. Hence, they chose Smartlead.

Challenges and Cold Email Tool Suitability

Before Using Smartlead

Growth Today faced the challenge of creating predictable and scalable outbound campaigns while managing a growing client base. Brigitta needed a tool to optimize and simplify email infrastructure while offering scalable solutions for high-volume email operations. The ideal tool needed to:

  • Ensure repeatability and scalability in outbound campaigns.
  • Provide advanced reporting and analytics for decision-making.
  • Manage bulk email infrastructure efficiently and effectively.

Why Smartlead?

Brigitta came across Smartlead through industry discussions in Slack groups and word-of-mouth from other cold email experts. Having tried tools that are spoken highly in the market, she didn’t find the right fit for her business needs. 

She found that Smartlead offered features specifically tailored to outbound operations, making it a perfect fit for their business needs.

Top Smartlead Features for Growth Today

  1. Bulk Inbox Management: Smartlead’s ability to manage multiple inboxes in bulk (e.g., signatures, sending volume, warmup limits) made it easier for Growth Today to handle large outbound email campaigns without sacrificing personalization.
  2. Detailed Reporting: The platform provided essential KPIs, such as positive response rates, allowing Brigitta to quickly evaluate and optimize outbound strategies.
  3. Advanced API Features: Smartlead’s API offered access to detailed data points, which helped automate workflows and extract important insights for internal use and client reporting.
  4. Sub-segments and Targeting: The tool’s segmentation capabilities ensured that emails reached the right prospects at the right time, increasing engagement.
  5. Affordable Price Point: Compared to other outbound tools, Smartlead’s competitive pricing enabled Growth Today to handle email infrastructure at a fraction of the cost.

//Brigitta says, “I want to continue to use Smartlead to make operations more seamless, so the plan is to bring more clients here and build more SOPs, systems around it to be able to onboard more clients and make everything super effective for us internally and for the clients.”

Impact and Benefits

Smartlead’s Role in Transforming Growth Today’s Operations

Since adopting Smartlead, Growth Today experienced significant improvements in their cold email operations. With 50+ email inboxes to manage per client, Smartlead drastically reduced the time spent setting up, updating, and monitoring email accounts.

  • Time Savings: Brigitta reported significant time savings from email infrastructure management. Smartlead’s features streamlined the process of managing multiple inboxes, allowing Growth Today to onboard more clients with fewer resources.
  • Reporting Efficiency: Smartlead’s data retrieval features allowed them to track and monitor campaign results in real time, feeding this data directly into their reporting dashboard. This improved their ability to make data-driven decisions and optimize email outreach strategies.

Notable Achievements with Smartlead

One notable milestone was Growth Today’s success in migrating the email infrastructure of a $5 million SaaS company to Smartlead. As a result, they increased the client’s open rates from 20% to 60%. The improved email deliverability directly contributed to better client satisfaction and a more effective outbound strategy.

Brigitta also attributed Smartlead’s affordable pricing to enabling Growth Today to offer competitive pricing for outbound services, which helped them secure more clients.

A Few Other Benefits

  • Email Infrastructure Costs: Saved thousands per month per client by reducing reliance on multiple tools and consolidating operations with Smartlead.
  • Improved Reporting: Automating data retrieval and push-to-dashboard functions for real-time campaign insights.

Feedback and Areas for Improvement

While Smartlead delivered excellent results, Brigitta wished there were more webhook capabilities that could accommodate a few more reporting requirements.

Additionally, the CRM functionality could be improved to allow more dynamic updates. 

She also wished there were more engagement-based filters to optimize targeting and outreach further.

"Brigitta says she is really excited and looking forward to seeing all the updates and features Smartlead has planned in the next months, especially the webbooks and analytics, which she believes are going to be a game changer for email deliverability."

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.

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

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.

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'.
