How SalesCaptain Scaled Cold Outreach Across 30+ Clients Using Mailforge’s Cold Email Infrastructure

SalesCaptain is a modern outbound agency helping B2B companies unlock consistent pipeline through personalized, data-driven cold email campaigns. As a Clay Enterprise Partner and one of Lemist's top global collaborators, they’ve worked with 60+ companies to scale performance-driven outbound programs.

But as Gmail and Microsoft crack down on mass outreach, SalesCaptain faced a critical bottleneck: their email infrastructure.

“If you’re struggling with cold email in 2025, stop tweaking subject lines and fix your infrastructure. That’s where the real leverage lives.”

Bill Stathopoulos
CEO at SalesCaptain

Why SalesCaptain Chose Mailforge

After testing every deliverability strategy and tool on the market, SalesCaptain made a strategic move: they migrated 70% of their cold email infrastructure to Mailforge.

Why? Because it works.

With Mailforge, they were finally able to control what mattered: reputation, consistency, and deliverability.

The Results

The shift to Mailforge helped SalesCaptain optimize inbox placement, improve reply rates, and scale reliably across dozens of campaigns - all without sacrificing control.

280+ Active Sending Domains
600+ Dedicated Cold Email Mailboxes

The Takeaway

SalesCaptain didn’t just level up their own deliverability - they built a resilient infrastructure stack that now powers cold outreach for dozens of clients.

With Mailforge, they gained the foundation to scale volume, maintain sender reputation, and stand out in increasingly noisy inboxes.

“We’ve seen deliverability improve campaigns for 60+ companies. Mailforge is now powering delivery for 30+ of our clients.”
