The AI SDR Infrastructure Stack: Warmforge, Infraforge, Megaforge Explained
Why do AI SDRs fail at cold email outreach? Often, it’s not their intelligence - it’s poor email infrastructure. Salesforge solves this with a three-layer system: Warmforge, Infraforge, and Megaforge, designed to ensure reliable email deliverability. Here's how it works:
- Warmforge builds trust with email providers by warming up new domains and mailboxes over 14 days.
- Infraforge gives businesses private email infrastructure with dedicated IPs, SSL certificates, and branded domains.
- Megaforge adds redundancy with multi-ESP support, spreading emails across Gmail, Outlook, and more to prevent disruptions.
This stack ensures AI SDRs like Agent Frank avoid spam filters, maintain high deliverability, and scale outreach effectively. Each layer addresses a specific challenge, from trust-building to infrastructure control to large-scale reliability. Together, they create a streamlined solution for cold email success.
1. Warmforge
Purpose
Warmforge tackles a key hurdle in cold email outreach: gaining the trust of email providers when using new mailboxes and domains. Providers like Gmail, Outlook, and Yahoo tend to flag new email addresses as suspicious. Warmforge steps in by automatically warming up these mailboxes over a 14-day period, helping to establish a solid sender reputation. This groundwork ensures reliable email delivery and sets the stage for Agent Frank to operate smoothly, as explained in the upcoming Core Features section.
Core Features
Warmforge gradually increases email volume over 14 days, automating the entire warm-up process. It integrates directly with Agent Frank, ensuring that outreach campaigns only begin once the mailboxes are fully prepared. This seamless handoff allows Agent Frank to focus on executing campaigns without a hitch.
Pricing
Here's the good news: Warmforge is included with every Salesforge subscription at no additional cost. Even better, it offers unlimited warm-up capabilities, so you can prepare as many mailboxes and domains as your business requires.
Ideal Use Case
Warmforge is perfect for businesses launching campaigns with new email accounts. As companies grow and need to add more sending addresses, Warmforge ensures those accounts are prepped and ready. This means Agent Frank can focus entirely on delivering precise, effective messaging without worrying about email deliverability issues.

2. Infraforge
Purpose
Infraforge is designed to offer businesses their own private cold email infrastructure, giving them complete control over email delivery.

This tailored setup forms the backbone for the advanced features it offers.
Core Features
Infraforge equips you with the tools to manage your email infrastructure effectively. Key features include:
- SSL certificates for secure communication
- Branded domain masking to maintain a professional appearance
- Multi-IP provisioning to spread out email volume and improve deliverability
These features work together to ensure your emails are delivered efficiently and securely.
Pricing
Starting at just $33/month for 10 mailboxes, Infraforge is a budget-friendly option for businesses looking to scale their cold email campaigns. Need more capacity? You can easily add additional mailboxes as your outreach grows, ensuring you only pay for what you use.
Ideal Use Case
Infraforge builds on the trust established with Warmforge by providing a dedicated infrastructure for your email outreach. It’s perfect for businesses that run regular cold email campaigns and need consistent, reliable delivery. For companies in competitive fields, where dependable email performance can make or break a campaign, Infraforge delivers the stability you need to stay ahead.
3. Megaforge
Purpose
Megaforge takes what Warmforge and Infraforge offer - trust and stability - and adds the power of scalability through a multi-ESP (Email Service Provider) approach. It’s the premium offering in the Salesforge infrastructure stack, crafted specifically to supercharge your cold email outreach. While Warmforge focuses on building sender trust and Infraforge ensures a rock-solid infrastructure, Megaforge steps in to diversify your email delivery across multiple providers. This strategy reduces the risk of relying on a single provider, safeguarding your sender reputation, boosting deliverability, and keeping your campaigns running smoothly - even if one provider hits a snag.
Core Features
This premium infrastructure has been created specifically for Agent Frank to boost email deliverability. Megaforge auto distributes sending across multiple ESPs, so if one burns, there’s a fallback.
It also offers smart distribution: 20 mailboxes (the base plan), evenly split across Gmail, Outlook, Mailforge and Infraforge mailboxes, sending ~15 emails/day each (300/day total).
Pricing
Starts at $69/mo for 20 mailboxes.
Ideal Use Case
Megaforge is the perfect complement to Warmforge, making it ideal for businesses that rely on high-volume, consistent email outreach. If your revenue depends on maintaining a steady pipeline, Megaforge’s multi-ESP strategy is designed to minimize risks associated with deliverability issues. Even if one provider fails, Megaforge ensures your campaigns keep running without interruption - protecting both your sender reputation and your revenue stream.
Advantages and Disadvantages
This section breaks down the pros and cons of each component in the stack, helping you weigh your options effectively.
| Component | Advantages | Disadvantages |
|---|---|---|
| Warmforge | • Included with any Salesforge subscription • Fully automated 14-day warm-up process • Builds sender reputation effectively |
• Requires a 14-day warm-up period to reach peak performance • Limited to the warm-up phase only |
| Infraforge | • Complete control over private infrastructure • SSL-secured, branded domain masking • Multi-IP setup for balanced email distribution • Predictable monthly pricing starting at $33 for 10 mailboxes |
• More expensive than shared email alternatives • Requires technical expertise for proper setup • Fixed monthly cost regardless of usage |

• Starts at $69/mo for 20 mailboxes. • Overkill for smaller-scale operations |
When these components work together, they create an ecosystem designed to boost deliverability and campaign performance. This integrated approach eliminates the hassle of managing multiple vendors and mismatched billing cycles, offering a unified solution that streamlines your outreach efforts.
Although the stack requires a higher initial investment, the benefits in terms of deliverability and campaign continuity make it a cost-effective choice for businesses focused on driving revenue. Cheaper shared email services may save money upfront but often come with risks, such as reputation damage from other users' activities. On the other hand, single-provider solutions lack the redundancy needed to ensure campaigns keep running smoothly when issues arise.
The modular nature of this stack also means you can scale as your needs grow, avoiding unnecessary costs early on. This flexibility, combined with the reliability and performance of Salesforge's integrated approach, provides a strong foundation for effective email outreach in today’s competitive landscape.
Final Thoughts
The Salesforge infrastructure stack marks a major change in how AI SDRs manage email deliverability and campaign stability. By combining multiple layers into one cohesive system, it sidesteps the common issues tied to shared or single-provider setups.
This integrated approach tackles cold email challenges head-on - whether it’s avoiding reputation hits from shared infrastructures, dodging campaign disruptions due to provider outages, or simplifying the juggling act of multiple vendors. Instead of patching together solutions and hoping for the best, this system offers a streamlined integration that reduces complexity and makes the infrastructure investment worthwhile.
Think about it: spam filters and email outages can cost far more than the price of a reliable infrastructure. Missed emails and stalled campaigns translate into lost revenue and strained client relationships - expenses no business can afford to ignore.
For companies aiming to maximize their AI SDR performance, this stack delivers the dependability and scalability needed for Agent Frank to excel. Unlike competitors relying on shaky shared systems, this design offers a clear advantage. Plus, its modular setup means you can start small and expand as your outreach grows, making it a smart fit for businesses at any stage of sales automation.
While flashy AI features might steal the spotlight, it’s the email delivery system that ensures your messages actually land in inboxes. Salesforge’s integrated stack provides the solid foundation your AI SDR needs to consistently deliver results, quarter after quarter.
