# Mailforge review (2026): is it worth $3 a month? > Shared-IP domains and mailboxes built for cold email sending Checked Nov 12, 2026 ยท graded Nov 12, 2026 by ToolGPA. Mailforge sells the domains and mailboxes that cold email is sent from. Each domain gets DKIM, SPF, DMARC and custom tracking set up automatically, and the mailboxes run on a shared IP pool and can be used with any sending software. It sits alongside Infraforge, which uses dedicated servers, in the same vendor's Forge stack. - **Category:** Cold Outreach - **Made by:** Mailforge - **Website:** https://www.mailforge.ai - **Runs on:** Web - **Who should skip it:** Skip it if you want a tool that sends campaigns, as it doesn't. - **Facts last checked:** Nov 12, 2026 ## Pricing As of Nov 12, 2026, Mailforge is a paid product, starting at $3 per mailbox slot / month, billed monthly, with a 10-slot minimum. - **Pricing model:** Paid - **Free plan:** None. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Mailbox slots | $3 per mailbox slot / month, billed monthly, 10-slot minimum | Slots are the capacity to create mailboxes and are charged whether used or not.

Prices change, so confirm with Mailforge 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.mailforge.ai/pricing ## Key features - **Automated DNS setup:** Each domain added gets DMARC, SPF, DKIM and custom domain tracking configured, with bulk DNS updates in the app. - **Shared IP pool:** Mailboxes are spread across a shared IP pool, in contrast with Infraforge's dedicated servers. - **Pre-warmed domains and mailboxes:** The page says domains and mailboxes can be bought pre-warmed so sequences can start right away. - **Workspaces and domain transfers:** Projects can have their own workspaces, and domains can be transferred in or out. - **Works with any sending tool:** Mailboxes connect to any sending software, including Salesforge from the same vendor. - **SSL and domain masking:** An add-on that redirects securely while masking the domain behind a branded website. ## Good for - Cold email senders who run many domains and mailboxes - Agencies that keep each client in a separate workspace - 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, and the minimum purchase is 10. - Domains are bought separately; the calculator prices .com at $14 a year, charged once, with no annual discount on domains. - There is no free trial; the app can be explored after sign-up, but domains and mailboxes must be purchased to send. - Each Forge product is a separate subscription, and SSL and domain masking costs $2 per domain a month. ## ToolGPA grades **GPA: 1.6 out of 4**, graded Nov 12, 2026. Mailforge sells the domains and mailboxes cold email goes out from, on a shared IP pool with SPF, DKIM, DMARC and tracking set up automatically. It's $3 a slot a month with a 10-slot minimum. It sends nothing itself, and domains are bought separately. - **Value for money: C.** $3 a slot a month billed monthly, with a 10-slot minimum, so $30 at the floor. Just above the category's cheaper quarter ($25), before domains. - **Free plan and trial: F.** No free plan or trial. You can look around after signing up, but sending means buying domains and mailboxes. - **Features: D.** Domains, mailboxes and DNS only. It needs a separate sender to be useful, and shared IPs share a reputation. - **Ease of use: C.** No store rating on record. DNS is automated, but domains, slots and a sender all have to be put together. - **Platforms and integrations: B.** Web with an API, and Salesforge, Infraforge, Warmforge and Primeforge from the same maker.

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 $36 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, Infraforge and Warmforge among them, and has an API. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
