Summary
First LLC, a B2B lead generation agency specializing in tech startups and scale-ups, transitioned from other tools to Smartlead to achieve superior scalability and cost-efficiency.
In their first year of agency scaling, founder Phil leveraged Smartlead's advanced automation features, particularly sub-sequences and out-of-office detection, to book 1,704 qualified calls for clients while managing thousands of daily emails across multiple European markets.
Client Background
Phil Sergenti founded First LLC (or Mailfirst) to help B2B companies in the tech sector—specifically startups and scale-ups—acquire qualified leads through cold outbound and LinkedIn strategies. The agency focuses on full demos and meetings, targeting prospects who aren't actively searching for solutions.
"You can really sell a consulting service to help hotels become dog-friendly. You can't sell that on Google or Facebook. You kind of have to go forward and meet people," Phil explained.
They operate across multiple European markets, requiring sophisticated multilingual campaign management. The agency's first full year represented a pivotal transition from solo consulting to a fully-fledged agency with dedicated inbox management teams.
Challenges
- Managing high-volume replies and scheduling follow-ups without automation
- Paying for unused and unnecessary features
- Limited lead data differentiation
- Managing multilingual campaigns
- Blind spots in inbox visibility are leading to a decline in team performance

Our Solution
After finding Smartlead "very famous in our industry," Phil made the switch based on cost-efficiency and focused features that directly addressed First LLC's operational needs.
Advanced Sub-Sequence Automation
Implemented sub-sequences as the foundation for inbox management, enabling automated follow-up scheduling across hundreds of daily replies.
"They really help when it comes to inbox management," Phil emphasized.
Out-of-Office Intelligence
Deployed automatic out-of-office detection with scheduled re-engagement, which is a critical feature most tools lacked—eliminating manual tracking for European vacation periods.
Superior Bounce Data Validation
Leveraged Smartlead's real sending data for email validation.
"The best one is actually real sending data... you have real hard data, which is, this actually bounced for three other users."
SmartProspect Database Integration
Utilized Smartlead's proprietary lead database, discovering 12% unique company coverage compared to Apollo while maintaining cost-efficiency.
AI-Assisted Multilingual Management
Tested Smartlead's AI auto-reply and auto-drafter technology to handle multilingual campaigns without expensive multilingual hiring, maintaining human oversight for quality.
Clay Integration for Advanced Targeting
Combined Smartlead's infrastructure with Clay's data processing to achieve the "fine targeting" and "nitty-gritty details" needed for non-commodity B2B services.

Why Smartlead?
Phil identified several critical factors that made Smartlead the superior choice:
- Cost-Efficiency with Focused Features
- Sub-Sequences for Volume Management
- Unique Out-of-Office Automation
- Superior Email Validation Data
- Exceptional Support Experience
"The product is solid. I don't feel like I need that many features because the basics are covered. What I need is actually what I'm getting."
