Choosing Between Mailforge vs Infraforge vs Primeforge

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.

• High-value outbound campaigns

• Anyone prioritizing reliability over cost

Limitations:

• Higher price point

• Less control over infrastructure

Limitations:

• No pre-warmed mailboxes

• 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.
