How StackOptimise Generated 40+ Leads in 2 Weeks Using Smartlead

For Felix Frank, founder of StackOptimise and a certified Clay expert, scaling cold email outreach for B2B and SaaS clients in the UK, US, and Europe was a critical challenge. As a sales rep turned agency owner, Felix knew the potential of outbound email but also recognized the limitations of traditional tools like Outreach and HubSpot. He needed a solution to handle high-volume, personalized outreach campaigns without sacrificing quality.

That's when Smartlead came into play. By leveraging Smartlead's powerful cold email marketing tool alongside Clay, Felix and his team built world-class sales-tech systems that drove impressive growth for their clients.

Challenges Faced Before Smartlead

Felix says, “We were having difficulty reaching out to multiple prospects and scaling our outreach efforts.”

Before adopting Smartlead, Felix and his team faced several obstacles in their cold email outreach efforts: 

Limited Email Volume

Using tools like Outreach and HubSpot, StackOptimise was restricted in the number of emails they could send. Sales reps were limited in how many prospects they could reach, which slowed down lead generation efforts. Felix needed a solution that would allow him to send more emails without compromising quality.

Primary Domain Risk

Felix’s team was using their primary domain for sending email sequences, which posed a risk to their sender's reputation. Sending high volumes of emails from a primary domain increased the chances of emails landing in spam folders, reducing the overall effectiveness of their campaigns.

Lack of Scalability

With existing tools, Felix struggled to scale his outreach efforts. While they could send personalized emails, the process wasn’t scalable enough to meet the growing demands of their B2B and SaaS clients. This limited the agency's ability to generate leads at a faster pace.

Using Smartlead, StackOptimise sent 9,075 emails to 5,346 unique leads in two weeks, achieving an outstanding one positive reply for every 124 leads contacted. This would have been impossible with their previous tools.

Inbox Rotation and Automation

Felix leveraged Smartlead’s inbox rotation and workflow automation features to optimize email deliverability and ensure that emails landed in the inbox rather than spam folders. This was a game-changer for their outreach campaigns, allowing them to scale efforts without compromising quality.

Smartlead enabled Felix to run six campaigns in just two weeks, generating 43 high-quality leads for his clients. The inbox rotation feature played a critical role in maintaining the scalability of these campaigns.

Centralized Inbox Management

One of Felix’s favorite features was the master inbox provided by Smartlead, which consolidated messages from all email accounts into one centralized location. This feature streamlined operations and made it easier to manage multiple inboxes and monitor campaign performance in real-time.

Smartlead’s mobile app allowed Felix to quickly check campaign progress and update tags in real-time, making it easier to manage outreach efforts on the go.
