Maildoso vs Infraforge: Cold 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 Maildoso and Infraforge unique.

Maildoso vs Infraforge: Cold Email Infrastructure Overview

• Infraforge pitches private cold email infrastructure with a focus on control - dedicated IPs, DNS automation, pre-warmed domains, and inbox health monitoring.

It's built for teams that treat deliverability as a core competency rather than a convenience.

• Maildoso positions itself as a rapid scale builder for cold outreach, automating domain and mailbox creation at high velocity.

Both platforms target cold email and cold outreach use cases, but Infraforge’s messaging centers on long-term sender reputation, flexibility, and private email infrastructure, while Maildoso emphasizes volume and easy inbox creation.

Pricing Structure

Infraforge provides flexible, usage-based pricing for dedicated-IP email infrastructure. A handy on-page calculator estimates your exact costs. Annual billing gives 2 months free.

Maildoso provides the following plans for shared IP email infrastructure (each plan billed quarterly).

• $100/mo for the 32 mailbox plan (8 domains included for free)
• $166/mo for the 68 mailbox plan (17 domains included for free)
• $733/mo for the 400 mailbox plan (100 domains included for free)
• $12 for each domain

Email Deliverability

Deliverability is the single biggest determinant of whether cold email campaigns succeed.

Infraforge emphasizes:

• Dedicated IPs
• Automated SPF, DKIM and DMARC setup
• SSL & domain masking
• Prewarmed mailboxes
• And multi-IP provisioning so that outages, blacklists, or poor hygiene on one sending lane don’t drag down the rest of your outbound emails.

Those capabilities feed a strategy that privileges a strong sender reputation through isolation and ongoing monitoring.

Infraforge also automates DNS configuration and offers pre-warmed domains and mailbox health tracking, which reduces manual setup errors that commonly land messages in spam filters.

Maildoso’s approach centers on:

• Scale-oriented warm-up
• Fast creation of many domains and mailboxes
• An AI warm-up tool that sends interactions designed to look like real engagement

Maildoso's approach can materially improve inbox placement for large-scale outreach if used carefully, though they don’t offer as many deliverability capabilities as Infraforge.

When a program needs to prioritize a private email path with per-IP control and granular deliverability consulting, Infraforge’s dedicated IP model and automated DNS best practices position it as a safer bet to keep spam filters at bay over time.

Both systems address inbox creation, but the architectural choices differ:

• Maildoso scales many mailboxes quickly,
• Infraforge structures sending to protect sender reputation across high volume sending,

Domains & Mailboxes

Managing domains and mailboxes well is crucial for running cold email campaigns without exposing a company’s main domain.

• Infraforge focuses on domains and mailboxes as part of a private email infrastructure stack where each domain can be provisioned with best-practice DNS records automatically and paired with dedicated IP addressing and mailbox slots.
• Maildoso markets the ability to create many domains and mailboxes quickly and features a primary domain protection model that hides the main domain behind captchas and redirects to shield it from being linked to secondary domains.

That makes Maildoso attractive for teams that want many domains and lots of multiple email addresses and domain forwarding in bulk with minimal friction.

Maildoso also offers whitelabel capabilities aimed at agencies.

But because Infraforge automates SPF, DKIM and DMARC setup and offers SSL & domain masking, it’s built so domains are created with deliverability-first defaults and domain pricing and IP pricing are transparent.

Infraforge similarly supports whitelabeling for agencies and resellers, enabling branded control panels and custom sending domains to maintain client-facing branding while keeping deliverability controls centralized.

For teams who need multiple domains and multiple mailboxes but want each domain to be treated as a first-class deliverability asset (not just a throwaway):

Infraforge’s automated DNS, masking, and per-domain tooling make managing replies, domain forwarding, and primary inbox hygiene simpler and more defensible over time.

Cold Email Campaign Scaling

If you’re running large-scale campaigns, the platform must support many mailboxes, domains, and orchestration with cold email tools and outreach platforms.

• Maildoso’s sales copy and pricing tiers are overtly built for scale: plan options advertise large bundles and the automation to create and connect mailboxes to outreach platforms “in just a few clicks.”

That makes Maildoso a practical starting point for agencies or larger teams that need to stand up hundreds of accounts fast.

• Infraforge addresses scaling with a different architectural promise. Rather than only pushing raw mailbox counts, it offers multi-IP provisioning, dedicated IPs per mailbox options, and automation that distributes outbound emails across IPs while preserving sender reputation.

For teams running many campaigns across many domains and multiple email addresses, this reduces the risks that come with high volume sending: a single misbehaving campaign won’t sink your primary inboxes or main domain.

Infraforge’s approach targets scale with safety - you get large scale campaigns capability while keeping strong sender reputation intact through isolation and monitoring.

Alternative Infrastructure 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, Maildoso's positioning does not advertise a connected family of infrastructure alternatives you can switch between or use in tandem on the same platform.

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.

Maildoso offers:

• A knowledge base
• API/developer docs
• And practical guides (deliverability, copywriting, beginner’s guide)

They run webinars and publish product updates, as well as hosting a Slack community, but they don't seem to offer 24/7 email or live chat support like Infraforge does.

Infraforge advertises consultative services and add-ons - such as expert sessions to diagnose outreach challenges - along with deliverability resources and onboarding that reduces setup time. Infraforge provides a programmatic API for provisioning dedicated IPs, automating DNS records, and integrating mailbox and deliverability controls into existing orchestration pipelines.

Besides that, Infraforge 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 Domains and Mailboxes Should You Pick For Your Cold Outreach Campaigns?

If your primary objective is just to spin up hundreds of accounts and run many large-scale campaigns quickly on a tight per-mailbox budget, Maildoso offers compelling plan options, an accessible user interface, and an AI warm-up tool that speeds inbox creation.

It’s a solid choice for sending cold emails fast, but if you'd like a Forge stack option - Mailforge is a great alternative.

However, if your business measures success by long-term inbox placement, consistent primary inbox delivery, and protecting a main domain while running multiple campaigns and multiple mailboxes, Infraforge’s dedicated IP infrastructure directly solves those risks.
