Best for dedicated-server mailboxes for cold email
Infraforge supplies the domains and mailboxes cold email goes out from, on dedicated servers and IPs. It's $4 a slot a month on quarterly billing, with a 10-slot minimum. It needs a sending tool beside it, and slots are charged whether you create a mailbox in them or not.
Who Infraforge is for
- Fits if you send cold email at volume and want dedicated IPs
- Works for agencies managing many domains through an API
Who Infraforge is not for
- Skip it if you want a sending tool, because you still need one
- Pricey if you add an IP, at $99 a month each
- Watch out: slots are billed whether or not a mailbox is created in them
- Not for you if you want a trial: there isn't one
Why Infraforge gets a 1.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for money$4 a slot a month on quarterly billing, with a 10-slot minimum, so $40 at the floor. That sits mid-category before domains and add-ons.
- FFree plan and trialNo free plan and no trial. Each Forge product is a separate subscription.
- DFeaturesDomains, mailboxes, DKIM, SPF and DMARC, warm-up and rotation. But it only supplies the sending infrastructure and needs another product to send.
- CEase of useNo store rating on record. Automatic DNS setup, but you buy domains, build slots and connect a sender.
- BPlatforms and integrationsWeb with an API, and a Forge family of Salesforge, Mailforge, Warmforge and Primeforge.

Keep Infraforge, or make your own?
Keep it
To replace Infraforge you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 43 of the 47 other cold outreach tools grade higher. It costs $48 a year.
What you could not
- A network of real inboxes that open and answer your emails.
- Reading the reports inbox providers send about your domain.
- It plugs into other products, Salesforge, Mailforge and Warmforge among them, and has an API.
What this rests on. Infraforge’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Infraforge?
Infraforge provides the domains and mailboxes cold email is sent from, hosted on dedicated servers and IP addresses rather than a shared pool. It sets up DKIM, SPF and DMARC automatically, adds warm-up, monitoring and sender rotation, and has an API for managing domains and mailboxes in bulk. It is a sibling product to Mailforge from the same vendor.
Worth knowing
- Slots are billed whether or not a mailbox is created in them, with a minimum of 10.
- Domains are bought separately; the calculator prices .com at $14 a year, charged once, with no annual discount on domains.
- Extra add-ons cost more: $99 a month per additional IP address, $2 per domain a month for SSL and domain masking, and $7 to $9 per workspace a month for Masterbox.
- There is no free trial, and each Forge product is a separate subscription.
Key features
- Dedicated servers and IPs
- Mailboxes send from dedicated servers, in contrast with Mailforge's shared IP pool; extra IP addresses can be added.
- Automated DNS setup
- DKIM, SPF and DMARC records are configured for each domain, with bulk DNS updates inside the app.
- Warm-up and monitoring
- The page lists automated warm-up, real-time deliverability monitoring and alerts, sender rotation and smart sending limits.
- API, MCP and CLI
- The Infraforge API is included with the subscription and can manage domains and mailboxes programmatically.
- Pre-warmed mailboxes
- Pre-warmed infrastructure is offered for sending right away.
- Workspaces and Masterbox
- Multiple workspaces, plus a Masterbox add-on that shows all emails across a workspace's accounts in one view.
