Comligo is a Spanish language training provider helping businesses and institutions improve communication skills through high-quality online language programs. As they expanded into new markets, Comligo needed a scalable outbound engine to reach decision-makers across multiple industries - without risking domain health or deliverability. They turned to the full Forge Stack - Salesforge, Mailforge, Primeforge, Warmforge, and Leadsforge - to build a high-volume, data-driven, and reputation-safe cold outreach system.
“With Warmforge, we’ve scaled outreach to thousands of institutions without ever worrying about domain reputation. Warmforge keeps our mailboxes healthy, Mailforge and Primeforge provide reliable infrastructure, and Salesforge ensures every message feels genuinely personal.”

The Setup
Comligo built a fully integrated outbound engine using the Forge Stack:
- Mailforge: Powering 180 active domains and 310 mailboxes for shared cold outreach at scale.
- Primeforge: Managing 80 active domains and 160 mailboxes using Google Workspace and MS365 mailboxes with U.S.-based IPs for premium deliverability.
- Warmforge (included in their Salesforge Growth subscription): Warming and continuously monitoring 386 mailboxes, all maintaining Heat Scores above 89, ensuring consistent inbox placement.
- Salesforge: Orchestrating outreach sequences with AI-personalized copy and campaign tracking across dozens of industries and buyer personas.
- Leadsforge: Powering lead discovery, generating over 100,000 verified leads across industries in the U.S., a volume that would have been nearly impossible to achieve through other prospecting platforms.
This combination gave Comligo a unified workflow - from lead generation to outreach execution - supported by a robust infrastructure foundation.
“We can scale confidently, knowing every email has the best chance of landing where it belongs - in the inbox.”

The Results
Comligo’s team scaled faster than ever while keeping deliverability airtight and engagement high.
The Takeaway
Comligo proves that volume doesn’t have to compromise quality or deliverability. With the Forge Stack, they’ve built an outbound system that finds, engages, and converts at scale - powered by reliable infrastructure and clean data.
