Enabling teams to operate seamlessly across multiple platforms is key to driving success in the fast-paced digital world. 

Imagine a company that’s not just integrating tools but transforming the way businesses handle their outbound sales and marketing. Picture this: you get streamlined workflows with enhanced efficiency, and reduced costs—all while enhancing your CRM experience.

This is exactly what OutboundSync, founded by Harris Kenny is all about. 

By harnessing the power of smart integrations, they've redefined how companies manage their outbound activities. 

Their approach combines innovative technology with practical solutions to ensure teams can focus on what they do best: connecting with prospects and closing deals.

Curious about how they pull it all together? Let’s dive into their story and see how Smartlead plays a pivotal role in their success.

Meet Harris Kenny and OutboundSync

Founded by Harris Kenny, who has over 15 years of experience in go-to-market strategies and has assisted over 100 companies, OutboundSync originated from his work at Intro CRM, a Gold Tier HubSpot Solutions Partner agency. 

OutboundSync bridges the gap between outbound sales and marketing tools and your CRM, allowing you to manage leads, deals, suppression lists, reports, and automation all within a single platform. This integration empowers revenue teams to operate efficiently and effectively, without leaving their CRM environment.

At its core, OutboundSync specializes in custom integrations, particularly between Smartlead and HubSpot. This integration enables revenue teams to leverage their outbound tools while consolidating data where they need it most. By centralizing data, OutboundSync simplifies lead management, report generation, and workflow automation.

The platform boasts a robust set of features, ensuring Smartlead integrates as natively as possible within HubSpot. With support for over 100 properties, users gain comprehensive control over their data. Key features include revenue attribution, lead routing, timeline events, contact properties, block lists, and native reporting.

Originating from a HubSpot and outbound agency that Harris had been running for the past three and a half years, OutboundSync was established to address the need for efficient data integration in outbound activities.

The primary users of OutboundSync are teams based in North America, particularly in the United States, with a growing presence in Europe. The main use case for the product is for teams that are on HubSpot or Salesforce, and they really want to orchestrate their outbound activity.

These users typically have advanced go-to-market processes that require precise orchestration of their outbound activities. This includes setting granular rules for outreach, implementing omnichannel workflows, and managing complex sales processes.

The Challenges Faced By OutboundSync

When Harris Kenny was running his agency, several significant challenges emerged that needed addressing:

1. High Cost of Maintaining Cold Emailing Infrastructure

Maintaining an effective cold emailing infrastructure was prohibitively expensive. Testing different tools to find the most cost-effective solution was an ongoing effort.

Existing tools in the market imposed limitations due to their pricing structures, making it difficult to scale efficiently.

2. Limited Flexibility with Existing Tools

The constraints of many tools hindered the ability to connect multiple accounts without incurring higher costs, affecting the overall efficiency and results of outbound campaigns.

3. Integration with CRM Systems

Clients often requested seamless integration with CRM systems like HubSpot and Salesforce. 

The ability to sync data effortlessly between cold emailing tools and CRMs was crucial for efficient workflow and reporting.

4. Development and Scaling of the Product

Developing a product that effectively integrates with both cold emailing tools and CRM systems required significant effort. 

The process of creating a low-code version and later enhancing it demanded substantial resources and time.

The Smartlead Factor 

Smartlead provided a transformative solution to the challenges faced by OutboundSync:

1. Cost Reduction

Smartlead's unique pricing model, which doesn't charge by connected account, allowed OutboundSync to reduce sending software costs by over 90%.

This cost reduction enabled the connection of more accounts and optimized sending per account (10-20 emails per day), resulting in better inbox performance and enhanced results for clients.

2. Flexibility and Scalability

The flexibility provided by Smartlead allowed OutboundSync to connect multiple accounts without increasing costs, fostering improved outcomes and reduced expenses.

This flexibility also enabled the company to move its entire agency over to Smartlead, leading to better results for users and significant cost savings.

3. Seamless Integration with CRMs

Building on top of Smartlead's webhook and API infrastructure allowed OutboundSync to meet client demands for integration with CRM systems like HubSpot and Salesforce.

Harris developed additional functionalities to sync data effortlessly, ensuring efficient workflow and accurate reporting within clients' CRMs.

4. Product Development and Growth

The continuous growth in users and volume within the Smartlead ecosystem reinforced Harris's decision to fully commit to the product.

The product's development process, from a low-code version to a fully developed solution, attracted meaningful paying customers and garnered substantial customer excitement.

5. Optimized Deliverability

Smartlead's engineering team is dedicated to ensuring high deliverability rates, which has been a game-changer for OutboundSync. This focus on deliverability allows the company to grow by connecting with new prospects and opportunities.

By using Smartlead, OutboundSync could navigate the complexities of email deliverability effectively. 

6. Omnichannel Approach

Smartlead supports an omnichannel approach that includes phone calls and manual LinkedIn steps, which OutboundSync has successfully adopted. 

This diversified strategy ensures compliance with platform rules and enhances outreach effectiveness without relying solely on email.

For OutboundSync, Smartlead acts as the first domino in the sequencing process, allowing the company to initiate their outreach via email and then follow up through other channels. 

This has significantly increased the chances of successful engagement and connection with new prospects.

Favorite Features:

Harris highlighted several key features of Smartlead that have been particularly beneficial for OutboundSync:

  • Webhooks and API: "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."
  • Cost-Efficiency: The ability to connect more accounts without additional charges has been a game-changer. "This is a really powerful feature," said Harris.
  • Campaign Configurability: Smartlead offers extensive control over campaign settings. "You can set a lot of different limits for different things, enabling and disabling features as needed. It really puts you in control as a user."

Apart from the above features, the open nature of Smartlead allowed OutboundSync to unbundle their operations. 

Instead of relying on an all-in-one provider, they could integrate with specialized tools like Clay for data acquisition. 

This approach saved significant costs and improved the quality of their campaigns. "By unbundling, we saved a significant amount of money on the data side and improved our outreach quality," Harris shared.

Harris also added how he is excited about Smartlead's new mobile app. Harris is pumped to check it out and believes it will be a gamechanger in lead management. 

Next Steps

As Smartlead continues to enhance its features and capabilities, OutboundSync is confident that these advancements will not only benefit their own operations but also provide substantial advantages to other users. 

With a keen eye on future developments, OutboundSync is committed to leveraging Smartlead's expanding toolset to further refine their email campaigns, improve deliverability, and drive even greater success in their outreach efforts. 

As they look forward to these new features and updates, OutboundSync is poised to continue optimizing their strategies and achieving outstanding results, with Smartlead being a great support.

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.

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.

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.

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'.
