MailScale vs Primeforge: Email Infrastructure Comparison

For a thorough understanding of what each option offers, a simplified comparison table isn't enough to grasp all intricacies that come with each tool, so let's dive deeper into what makes MailScale and Primeforge unique.

MailScale vs Primeforge: Cold Email Infrastructure Overview

Both MailScale and Primeforge position themselves as specialists for cold email infrastructure: software and services that help sales teams, agencies, and solopreneurs manage multiple email accounts and sending domains for cold email campaigns.

MailScale emphasizes rapid, shared-IP inbox creation, and the raw ability to generate up to 1,000 email accounts so you can “send 5x more cold emails” while keeping per-inbox daily volumes low.

That messaging targets teams that want a basic volume-first approach to scale cold outreach with many email inboxes.

Primeforge presents itself as a Google & Microsoft mailbox provider tuned for cold outreach with:

• Preconfigured, deliverability-forward mailboxes
• Automated setup of DNS records and authentication
• And tools to monitor inbox placement and reputation

Where MailScale leans into scaling many accounts quickly, Primeforge focuses on making each inbox perform better out of the box via automated setup, high reputation email provider usage, and deliverability tooling designed specifically for cold email.

Both vendors make claims about automated setup, creating inboxes, and saving significant time vs manually creating accounts, but these nuances are important.

MailScale sells the scale, but Primeforge sells a richer deliverability-first stack for maintaining high deliverability.

Pricing Structure

Primeforge provides flexible, usage-based pricing for Gmail and Outlook email infrastructure (you buy domains + mailbox slots). A handy on-page calculator estimates your exact costs. Annual billing for mailboxes gives 2 months free.

• $14/year per .com domain. Use the calculator to see how many domains you’ll need for your sequences.
• $4.5/Mailbox Slot/month. Minimum purchase: 10 mailbox slots.
• With annual billing the effective cost for 10 slots is $38/month.

Extras

• Forge Expert Double Session: $500 for two 1:1 consulting sessions

MailScale provides packaged plans that charge by number of inboxes (plus domains you buy inside the app).

• Solopreneur - $79/month (up to 10 inboxes)
• Business - $119/month (up to 30 inboxes)
• Enterprise - $249/month (up to 95 inboxes)
• Unlimited - $1000+/month (unlimited inboxes)
• Domains are purchased inside MailScale, .com ≈ $15 / year
• Pre-warmed inboxes add-on: $99/month for 20 pre-warmed inboxes (upgradeable)

Technical Setup

Manually creating email accounts, buying domains, adding DNS records, configuring SPF/DKIM, setting up DMARC, and integrating with Google Workspace or other email providers can take significant time and make way for various mistakes.

MailScale markets itself as replacing the “old way” where teams manually set up domains and DNS records. It automates domain onboarding and inbox creation to drastically reduce the technical setup burden and help scale cold email infrastructure fast.

That automation is a great capability if your priority is “more email accounts, faster", but Primeforge doesn't shy away from offering the same capability either.

Primeforge also advertises automated setup - highlighting free automated setup for each domain and mailbox they sell, including DMARC, SPF, DKIM, and custom domain tracking.

Where Primeforge leans ahead is in how it packages the automated setup.

Primeforge’s automated setup ties directly into deliverability checks and real-time placement testing, which reduces the manual tinkering that typically costs significant time and introduces risk when growing teams buy multiple domains and multiple inboxes.

Deliverability Controls

Deliverability is the metric that most directly affects whether cold email campaigns succeed.

One of MailScale’s value propositions includes automating DNS steps so newly created inboxes don’t fall prey to misconfigured DNS records or common manual errors.

Primeforge also touts free, automated setup that configures DMARC, SPF and DKIM, as well as custom domain tracking for each domain and mailbox you buy, and pairs that with inbox placement testing and blacklist monitoring.

The distinction here is meaningful:

MailScale removes the manual pain of adding DNS records

Primeforge removes that pain, while presenting those DNS and authentication steps together with continuous checks that are designed to maintain sender reputation rather than only achieving a “working” setup.

Google Workspace & Microsoft 365 Mailboxes

Integrations matter because most teams use a sending tool, CRM, or Google Workspace as part of their outreach stack.

• MailScale advertises that you can plug MailScale inboxes into many email sending tools and frames itself as faster than buying native Google or Outlook accounts.

But Primeforge sells preconfigured Google & Microsoft mailboxes substantially faster than other Gmail and Outlook providers.

• Primeforge can even deliver fully configured inboxes in about 30 minutes and nearly 50% the cost of buying directly from Google Workspace - a major operational and cost advantage for teams that want inboxes in a Google Workspace or Microsoft 365 environment with less manual setup.

Not to mention, Primeforge's mailboxes can be pushed into any sending platform of your choice.

Mailbox Profile Pictures

Primeforge offers animated GIFs as a built-in personalization feature: you can upload short, subtle GIFs and push them as profile images across Google Workspace or Microsoft 365 inboxes - including bulk rollout for teams during mailbox provisioning.

That makes GIFs a simple, one-click branding/personalization step tied into Primeforge’s advanced setup.

MailScale does not support profile pictures/GIF profile images in its platform, therefore if you want the personalization boost from GIF deployment in profile pictures, MailScale won’t provide that.

Customer Support & Resources

When you’re running critical outreach for revenue, access to expert support can be the difference between a quick fix for a DNS misconfiguration and days of deliverability loss.

MailScale offers standard customer support channels, a help center, and training pages that guide users through creating accounts, managing domains, and integrating sending tools.

Primeforge advertises consultative services and add-ons - such as expert sessions to diagnose outreach challenges - along with deliverability resources and onboarding that reduces setup time

Besides that, Primeforge also offers:

• 24/7 email and live chat support
• Extensive documentation
• Youtube tutorials
• And even weekly AMA sessions

Final Verdict - Which Email Inboxes Should Your Team Choose For Your Cold Email Outreach Campaigns?

If your priority is pure volume, MailScale is a decent tool that helps with inbox creation and scale cold outreach.

The platform is a good fit for agencies and growth teams that already have mature warm-up and deliverability processes or who want a very low friction way to get many email inboxes.

However, if you need the entire process handled with high attention to inbox placement, long-term sender reputation, and a user-friendly route from purchasing mailboxes to maintaining high deliverability without stitching multiple tools together, Primeforge offers the perfect alternative.

Primeforge’s free automated DNS setup, real-time placement testing, warm-up orchestration, and case-study-backed workflows reduce the operational risk that causes deliverability issues for growing teams.

For sales teams, agencies, and enterprise plans that cannot afford spam issues, Primeforge’s integrated approach translates into better deliverability, fewer extra tools to buy, and more control over sender reputation.
