Best for bulk mailboxes for cold email on shared IPs
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.
Who Mailforge is for
- Fits if you want cheap mailboxes for a sequencer you already pay for
- Works for small senders happy on shared IPs
Who Mailforge is not for
- Skip it if you want a tool that sends campaigns, as it doesn't
- Not for you if you want a trial, since there isn't one
- Watch out: slots are charged whether or not a mailbox is created
- Pricey if you add domains and masking: .com is $14 a year and masking is $2 per domain a month
Why Mailforge 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$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.
- FFree plan and trialNo free plan or trial. You can look around after signing up, but sending means buying domains and mailboxes.
- DFeaturesDomains, mailboxes and DNS only. It needs a separate sender to be useful, and shared IPs share a reputation.
- CEase of useNo store rating on record. DNS is automated, but domains, slots and a sender all have to be put together.
- BPlatforms and integrationsWeb with an API, and Salesforge, Infraforge, Warmforge and Primeforge from the same maker.

Keep Mailforge, or make your own?
Keep it
To replace Mailforge 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 $36 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, Infraforge and Warmforge among them, and has an API.
What this rests on. Mailforge’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 Mailforge?
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.
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.
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.
