# Choosing Between Mailforge vs Infraforge vs Primeforge

A clear comparison of Mailforge, Infraforge, and Primeforge to help you choose the right cold email infrastructure and understand when to combine them for better deliverability and scale.

If you're setting up cold email infrastructure, the tool you pick will affect deliverability, scalability, and how much control you actually have.

Mailforge, Infraforge, and Primeforge all let you create domains and mailboxes. The difference is how that infrastructure is built.

## The core difference

-   Primeforge: Google Workspace and Microsoft mailboxes
    
-   Infraforge: SMTP/IMAP infrastructure with dedicated IPs
    
-   Mailforge: SMTP/IMAP infrastructure with shared IPs
    

Everything else comes down to tradeoffs between cost, control, and deliverability.

## Primeforge

Real reseller Google Workspace and Microsoft 365 mailboxes, configured for cold outreach.

-   Higher inbox placement through ESP matching
    
-   Pre-warmed mailboxes available
    
-   Automated setup with DNS handled for you
    
-   Stable, predictable deliverability
    

Best fit:

-   Agencies and sales teams
    
-   High-value outbound campaigns
    
-   Anyone prioritizing reliability over cost
    

Limitations:

-   Higher price point
    
-   Less control over infrastructure
    

## Infraforge

Private email infrastructure with dedicated IP addresses.

-   Full control over sending reputation
    
-   No shared IP risk
    
-   Pre-warmed mailboxes available
    
-   Automated DNS and setup
    

Best fit:

-   Agencies and advanced users
    
-   High-volume outbound
    
-   Teams that want control and flexibility
    

Limitations:

-   Requires understanding of deliverability
    
-   Mistakes can impact performance faster
    

## Mailforge

Shared infrastructure built specifically for cold email.

-   Lowest cost per mailbox
    
-   Fast setup in minutes
    
-   Automated DNS configuration
    
-   Pre-warmed mailboxes available
    
-   No technical overhead
    
-   Works with any sending tool
    

Best fit:

-   Beginners
    
-   Small teams
    
-   Testing and early-stage outbound
    

Limitations:

-   Shared IP reputation
    
-   Less control at scale
    

## Deliverability

-   Primeforge: strongest baseline due to Google and Microsoft infrastructure
    
-   Infraforge: high ceiling, depends on how well you manage it
    
-   Mailforge: solid but can depend on other users activity due to shared IP infrastructure
    

## Cost

-   Mailforge: lowest
    
-   Infraforge: mid-range
    
-   Primeforge: highest
    

## Ease of Use

-   Mailforge: easiest to start
    
-   Infraforge: simple setup, more involvement over time
    
-   Primeforge: straightforward, but tied to Google and Microsoft environments
    

## When to choose each

-   Mailforge: starting out or keeping costs low
    
-   Infraforge: scaling with control
    
-   Primeforge: maximizing deliverability and stability
    

## You don’t have to choose just one

One common mistake is treating these options as mutually exclusive.

In reality, the best-performing outbound setups use a mix of infrastructure.

Different providers behave differently when it comes to deliverability. Relying on a single system increases risk and limits your ability to scale safely.

A more effective approach is to diversify.

-   Use Primeforge for Google Workspace and Microsoft mailboxes
    
-   Use Infraforge or Mailforge for SMTP/IMAP infrastructure
    

This gives you two key advantages:

-   Access to high-trust ecosystems like Google and Microsoft
    
-   Additional sending capacity through dedicated or shared SMTP infrastructure
    

In practice, this means:

-   Primeforge handles deliverability-focused sending
    
-   Infraforge and/or Mailforge supports volume and scaling
    

Most advanced teams move in this direction once they start scaling.

## Final takeaway

-   Mailforge: simple and affordable
    
-   Infraforge: powerful and flexible
    
-   Primeforge: stable and deliverability-focused
    

The right choice depends on how much you value cost, control, and consistency.
