Inframail vs Primeforge: Cold Email Infrastructure Overview

Inframail and Primeforge approach cold email infrastructure from different angles, and understanding the distinction is the first step in picking the right tool for your outreach efforts.

  • Inframail markets itself as a super-fast, agency-focused email setup platform that emphasizes automated email setup, quick domain purchase, unlimited inboxes and automatic SPF, DKIM and DMARC records to help teams create unlimited email inboxes quickly.
  • Primeforge offers many of the same features, but centers itself around Google and Microsoft mailboxes with free automated setup, bulk DNS updates, and workspace features that make it incredibly straightforward for teams to manage multiple mailboxes and personalized outreach campaigns.

Meanwhile, the broader Forge product family (Mailforge and Infraforge) shows how the market fragments:

  • Mailforge emphasizes distributed, cost-efficient inbox creation, with a slot-based pricing model for cheap mailbox scale
  • Infraforge leans into private infrastructure, multi-IP/dedicated IP capabilities, and deeper control for those who want full control over sending infrastructure.

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.

Inframail provides flat pricing plans built around unlimited inboxes (you pay by plan, not per mailbox). Annual billing gives a slight discount.

  • $99/mo (+tax) Unlimited plan (includes unlimited email inboxes, 1 dedicated US IP, free automated email/setup tooling, 1:1 deliverability consultant)
  • $249/mo (+tax) Agency plan (includes in Unlimited plan, 3 dedicated US IPs, higher domain/setup capacity, priority support)
  • Done-For-You (DFY) Email Campaign Setup options (one-time - $3,497 + tax, monthly - $299/month + tax). Typically includes automated warm-up, account setup and a dedicated coach.

Setup Process

Onboarding and the setup process determine how quickly your team can start sending cold emails and how well your early outreach avoids spam folders and high bounce rates.

  • Inframail pushes a quick domain purchase flow and “3 click mailbox creation." Their unique selilng point is support for unlimited email inboxes for rapid scaling.
  • Primeforge's free automated setup and bulk DNS updates reduce the friction of SPF/DKIM/DMARC configuration, enabling fast setup and a smoother setup process for domain setup and inbox creation.

That means sales teams and agencies get API access and fast setup without wrestling with manual DNS edits.

The practical difference is nuance:

  • Inframail emphasizes scale.
  • Primeforge’s onboarding emphasizes stability and quality.

For teams that want to create unlimited email inboxes and start sending cold emails quickly but still want structured domain setup, Primeforge’s automated setup + its deliverability-focused onboarding makes it easier to manage outreach efforts while reducing mistakes.

Domain & DNS Management

Domain setup and DNS handling are the unsung heroes of long-term deliverability.

  • Primeforge provides bulk DNS updates and automated domain-related setup so you don’t need to manually add SPF/DKIM/DMARC records for each domain - a real boon if you manage multiple domains or plan inbox rotation and multiple mailboxes.
  • Inframail advertises automated SPF/DKIM/DMARC setup as core parts of its fast setup pitch, enabling inbox creation at scale.

For practical outreach, domain setup quality affects whether emails land in the primary inbox or the spam folder, and whether your sender reputation remains healthy as you scale.

Primeforge’s bulk DNS flow and automated setup make domain setup easier for small teams and agencies running multiple campaigns, reducing errors that would otherwise hurt deliverability.

If your priority is safe, repeatable domain setup across many domains, Primeforge’s model (automated setup + bulk DNS updates) tends to reduce mistakes during the setup process.

Deliverability & Sender Reputation

Deliverability is the metric that ultimately decides campaign success: you can launch cold email campaigns, but if emails don’t reach the primary inbox, reply rates and ROI fall.

  • Primeforge frames its product around improving deliverability for Google and Microsoft mailboxes used for cold outreach, handling DMARC, SPF and DKIM setup for each domain and mailbox to protect sender reputation + tools that track inbox placement and advanced ESP matching for guaranteed landing in primary inboxes.
  • Inframail's deliverability claims are tied to rapid setup and automated authentication, which is attractive for teams that need quick wins. Infraforge also emphasizes monitoring to give long-term control over sender reputation.

In practice, better deliverability comes from combining solid domain setup (SPF/DKIM/DMARC), gradual warm-up, sensible sending limits, utilizing ESP matching, and ongoing monitoring of bounce rates and spam filters.

Primeforge’s emphasis on automated authentication and deliverability-focused flows helps teams get the basics right quickly, reducing the common errors that push cold outreach into spam folders.

For teams prioritizing immediate, reliable deliverability with simple operational workflows, Primeforge tends to make fewer manual configuration missteps and therefore helps emails reach prospects more consistently.

GIF Mailbox Profile Pictures

Mailbox profile pictures are a surprisingly useful lever for personalized outreach campaigns when used thoughtfully.

  • Primeforge offers the ability to customize mailbox profile pictures and even GIFs. A thumbnail avatar in recipients’ clients can increase recognition, trust signals, and the likelihood your message is noticed in an overloaded primary inbox.

Adding a professional static avatar or a subtle GIF complements good copy and targeting, but Inframail offers no such capability.

It gives recipients visual context that your message comes from a real person or brand, which can nudge messages out of the spam folder and into the primary inbox when combined with correct record setup and careful warm-up.

Alternative Options: Shared IP & Private IP Email Infrastructures

Salesforge uniquely bundles alternative infrastructure choices into a single stack:

  • Primeforge (Google Workspace & MS365 mailboxes) for ESP-matched deliverability
  • Mailforge for shared IP infrastructure needs
  • Infraforge for private, dedicated-IP infrastructure and more customizable control

That product architecture means a single vendor can support multiple outbound campaigns and use-cases - from teams that want to manage multiple domains and multiple accounts cheaply, to heavy hitters who need dedicated IP provisioning or fine-grained control.

  • By contrast, Inframail's positioning does not advertise a connected family of infrastructure alternatives you can switch between on the same platform. They focus on one primary cold email infrastructure solution.

For buyers weighing long-term lead generation and cold email outreach, this matters.

Having integrated alternatives (ESP-matched mailboxes + shared infra + private infra) inside one suite preserves CRM integration, feedback loops, and the ability to run deliverability tests and reputation monitoring under the same platform umbrella.

This saves time, reduces manual DNS setup and plan friction when adding new domains or new users, and helps maintain stable sender reputation as your sending volume scales.

Customer Support

Customer support models differ a lot between providers and that difference matters for adoption, troubleshooting deliverability, and long-term campaign health.

Inframail’s help pages and FAQ show a mix of Intercom and email support, which is typical for platforms geared at agencies that want both self-serve documentation and a human-assisted DFY option.

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
  • An active Slack community
  • And even weekly AMA sessions.

In practice that means fewer technical steps for your team, less manual work mapping records across registrars, and fewer hours spent troubleshooting or waiting for a response.

Final Verdict: Which Infrastructure Should You Pick For Your Cold Email Outreach?

For teams prioritizing long-term success and “emails reach the inbox” reliability without building a full private stack, Primeforge’s combination of free automated setup, bulk DNS updates, ESP matching, and other deliverability-minded features makes it a highly practical choice.

Inframail is an attractive option if you run an agency that needs bulk inbox creation and automated SPF/DKIM/DMARC during the setup process.

But if your aim is to maximize replies, keep bounce rates low, and avoid the spam folder while still benefiting from a fast setup and multiple mailboxes, Primeforge’s operational balance and integrations with practically all cold email sending tools make it the perfect tool for the job.

What is Primeforge and how does it differ from Inframail or traditional email services?

Primeforge focuses on ESP-matched Gmail/Outlook mailboxes with automated domain/DNS setup and deliverability flows, unlike traditional email services that leave DNS and warm-up to you. Inframail, by contrast, pitches unlimited inboxes and rapid agency scaling; Primeforge emphasizes stability, authentication and workspace-style mailbox management.

Primeforge automates SPF/DKIM/DMARC, bulk DNS updates and workspace setup to improve email deliverability for cold email campaigns. It includes or integrates with warm-up tools and cold email software, and pairs those with monitoring and ESP matching to reduce common configuration mistakes that hurt inbox placement.

Is Primeforge a good fit for sales teams and what about pricing/support?

Yes - sales teams benefit from Primeforge’s flexible pricing (mailbox slots + domain costs), workspace features, and integrations with multiple tools. It’s built as cold email infrastructure that ties into existing CRMs and cold email tools, with support resources and onboarding aimed at making multi-account outreach reliable and repeatable.
