# Infraforge review (2026): is it worth $4 a month? > Private cold email infrastructure on dedicated IPs Checked Nov 12, 2026 ยท graded Nov 12, 2026 by ToolGPA. 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. - **Category:** Cold Outreach - **Made by:** Infraforge - **Website:** https://www.infraforge.ai - **Runs on:** Web - **Who should skip it:** Skip it if you want a sending tool, because you still need one. - **Facts last checked:** Nov 12, 2026 ## Pricing As of Nov 12, 2026, Infraforge is a paid product, starting at $4 per mailbox slot / month, billed quarterly, with a 10-slot minimum. - **Pricing model:** Paid - **Free plan:** None. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Mailbox slots | $4 per mailbox slot / month, billed quarterly, 10-slot minimum | Slots are charged whether or not a mailbox is created.

Prices change, so confirm with Infraforge before buying. ## Ways to pay less - **Two months free on annual mailbox billing** (Annual discount): The FAQ says annual billing for mailboxes gets 2 months free automatically; there is no discount on domains. Source: https://www.infraforge.ai/pricing ## 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. ## Good for - Senders who want dedicated IPs for cold email - Agencies and teams that provision many mailboxes through an API - Teams that already have a sending tool and need only the infrastructure ## 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. ## ToolGPA grades **GPA: 1.6 out of 4**, graded Nov 12, 2026. 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. - **Value for money: C.** $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. - **Free plan and trial: F.** No free plan and no trial. Each Forge product is a separate subscription. - **Features: D.** Domains, mailboxes, DKIM, SPF and DMARC, warm-up and rotation. But it only supplies the sending infrastructure and needs another product to send. - **Ease of use: C.** No store rating on record. Automatic DNS setup, but you buy domains, build slots and connect a sender. - **Platforms and integrations: B.** Web with an API, and a Forge family of Salesforge, Mailforge, Warmforge and Primeforge. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Infraforge's own pages on 12 November 2026.

Nothing scores higher for less, though at least one tool matches that score at a lower price.

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. - You could not: A network of real inboxes that open and answer your emails. - You could not: Reading the reports inbox providers send about your domain. - You could not: It plugs into other products, Salesforge, Mailforge and Warmforge among them, and has an API. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
