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 Mailforge unique.
At a high level both Maildoso and Mailforge present themselves as cold email infrastructure providers that let sales teams and agencies run cold email campaigns and outbound campaigns without the heavy manual work of registering domains, doing DNS setup, or hand-configuring inboxes.
The practical difference lies in what each platform treats as core to the cold email solution.
Mailforge markets a structured, deliverability-first cold email infrastructure with:
That together aim to give teams predictable governance as they manage multiple domains, multiple email addresses and high volume sending.
Maildoso bundles features around speed and operational simplicity.
Domains and email accounts can be registered and provisioned in the dashboard, inbox creation is fast (the site claims 250 domains and 1,000 mailboxes in ten minutes), and the product centers on practical features for outbound emails such as domain forwarding and daily inbox placement tests.
But where they diverge matters to real teams deciding between them:
Both improve email deliverability compared with DIY setups, but if you value advanced features, multi-workspace governance and an integrated, enterprise-accessible cold email infrastructure, Mailforge is the option for your business.
Mailforge provides flexible, usage-based pricing for shared IP email infrastructure (you buy domains + mailbox slots). A handy on-page calculator estimates your exact costs. Annual billing for mailboxes gives 2 months free.
Add-ons & extras
Maildoso provides 3 plans for shared IP email infrastructure (each plan billed quarterly).
Mailforge is built around speed, with most users having ready mailboxes in under 5 minutes, and automated DNS setup.
It repeatedly emphasizes free, automated setup, bulk DNS updates, and a convenient calculator for domains and mailbox counts for teams who want a repeatable cold email infrastructure pattern for outbound campaigns.
That same focus on fast onboarding is part of Mailforge’s value proposition for sales teams and agencies that must run large scale campaigns with many sending domains and multiple accounts too.
Maildoso also emphasizes a fairly quick setup flow: domains can be registered directly in the dashboard and SPF/DKIM/DMARC are auto-configured.
Maildoso’s onboarding has extra pieces like domain forwarding and the master inbox concept that simplify reply management immediately after setup.
Both platforms therefore substantially reduce manual DNS setup and inbox creation, but the practical difference is Mailforge’s focus on bulk DNS tooling and workspace organization.
If your priority is minimizing manual DNS and getting a predictable, auditable bootstrap for complex outreach stacks and CRM integration later, the Mailforge flow reads as engineered for that operational predictability.
DNS setup and who “owns” the domains drives both deliverability and compliance.
Mailforge advertises free automated set up and explicitly calls out that for each domain they take care of DKIM, DMARC and SPF and offer bulk DNS updates inside the app - a massive time-saver for teams running many sending domains and email accounts.
Mailforge also supports domain transferring and SSL/domain masking for advanced use cases. This translates into a managed DNS experience where the platform aims to minimize manual edits and to help teams manage multiple domains in an organized way.
Mailforge’s documentation and UI emphasis around bulk DNS edits and domain transferring means it was built for managing campaigns where domain pricing and domain lifecycle are operationally important.
Maildoso’s site likewise emphasizes automatic SPF/DKIM/DMARC configuration, with domain forwarding that redirects prospects to your primary site by default.
Both systems promise that new domains and new domains’ DNS are handled automatically, but the nuance is Mailforge’s bulk DNS tooling and multi-workspace organization for teams that must manage granular DNS changes across many sending domains and multiple accounts.
A core decision for any cold email system is how it handles IP addresses and sending infrastructure under high sending volume.
Mailforge promotes a distributed, shared IP setup optimized for cold outreach and premium deliverability at scale.
But the Forge stack also offers:
Maildoso, on the other hand, solely focuses on shared IP infrastructure.
The tradeoff between these philosophies is straightforward:
Mailforge places a heavy emphasis on deliverability too: free inbox placement tests, DKIM/SPF/DMARC checkers and a dedicated, state-of-the-art deliverability center via Warmforge.
Mailforge presents a whole suite of checkers and tests (Inbox Placement Test, DKIM checker, guides, etc.)
Maildoso advertises daily inbox placement tests and a mailbox reputation dashboard so you know where your emails are landing.
They combine automated placement checks with reputation monitoring and claim to run deliverability tests as part of their offering.
If you want an integrated set of diagnostics and a clear operational scaffold to run tests, interpret results and iterate on sending patterns, Mailforge makes that an explicit part of the product story + it ties nicely into the Forge suite of tools.
Maildoso includes deliverability audits for customers, a knowledge base, a Slack community and coaching/webinars - plus product updates showing new features like an API and reputation measurement.
Mailforge takes support to the next level with:
And a general customer-success focus on helping teams optimize everything from domain configuration to sequence performance.
Both platforms are purpose-built cold email solutions that reduce manual DNS setup, let you create multiple domains and multiple mailboxes quickly, and provide warm-up tooling, deliverability tests and reputation monitoring.
If your priority is the fastest way to spin up thousands of mailboxes and an all-in-one master inbox, Maildoso’s proposition is compelling.
If, however, you prioritize an affordable product that emphasizes:
Then Mailforge is the more structured pick and the better fit for teams that need advanced features, reliable DNS tooling, and an enterprise-style operational scaffold for cold outreach.
Mailforge sells mailbox slots and automates bulk DNS for domains and email accounts, letting you attach own domains, a primary domain and many secondary domains for scalable cold email outreach. Maildoso focuses on rapid inbox creation and published plans (Maildoso pricing tiers start higher per-bundle), but Mailforge’s slot + domain model often costs less per active campaign while giving stronger domain governance for longer-term sender reputation.
Mailforge emphasizes deliverability: automated SPF/DKIM/DMARC, warm-up tooling, shared IP pools and optional private IPs (Infraforge) to control reputation across cold email campaigns. Maildoso uses shared IPs and fast provisioning; Mailforge’s multi-IP options and warm-up processes reduce blocks and improve primary inbox placement for sustained outreach compared with purely volume-first cold email tools.
Mailforge’s UI is built for multi-workspace governance - manage domains and email accounts, assign primary domain and primary inbox, and organize secondary domains per campaign. It integrates with cold email tools, shows deliverability tests, and centralizes DNS edits. Maildoso’s dashboard prioritizes rapid provisioning and a master inbox, but Mailforge trades some raw speed for clearer controls that reduce operational risk during scaled cold email outreach.
