Infraforge Review 2026
Last reviewed October 2026 by Théo Pascard
Infraforge
Private cold email infrastructure with dedicated IPs, from the Forge family
Overview
Infraforge sells domains and mailboxes for cold email on what the vendor calls private infrastructure: dedicated servers and dedicated IPs rather than a shared pool. It automates DNS records (SPF, DKIM, DMARC) and updates DNS in bulk. It also offers pre-warmed mailboxes, workspaces, SSL and domain masking, extra IPs, and a Masterbox view of all inboxes in a workspace. It has an API, and the homepage lists MCP and CLI access. Infraforge is the dedicated-IP sibling of Mailforge in the Forge family that G2 lists under the seller Salesforge, and it works with any sending software. Pricing is per mailbox slot, with a minimum of 10, billed quarterly or yearly, plus .com domains.

- →Teams that want to automate their infrastructure through an API

What is the difference between Infraforge and Mailforge?
Both belong to the same Forge family. According to the vendor's FAQ, Infraforge sends from dedicated servers, while Mailforge spreads mailboxes across a shared IP pool. The vendor says neither is inherently better. It suggests Mailforge if you expect many spam reports, and Infraforge if you follow deliverability best practices closely. Infraforge's entry price is 4 USD per slot a month against 3 USD for Mailforge.
What is a mailbox slot?
A slot is the capacity to create one mailbox. You are charged for every slot you buy, even if you create fewer mailboxes, and you can delete and recreate mailboxes at no extra cost. The minimum purchase is 10 slots. The vendor recommends 30 emails per mailbox per day, up to 100, and 2 to 3 mailboxes per domain.
Does Infraforge offer Google or Microsoft mailboxes?
Not on its own pricing page. The site presents Infraforge as private infrastructure. Buyers who want Google or Microsoft mailboxes are sent to Primeforge, which the site describes as Google or Microsoft mailboxes on US IPs.
What do Infraforge users say about it on G2?
In October 2026 Infraforge showed 4.7 out of 5 on G2 from 60 reviews. G2 did not publish a tagged pros and cons breakdown for the product, so there are no theme counts to report. The homepage shows a 4.9 rating without naming its source, which is not the G2 figure above.
What are the best Infraforge alternatives?
MailReef is the closest in kind: dedicated sending infrastructure for high-volume cold email. Zapmail sells pre-warmed Google and Microsoft mailboxes set up in minutes. Hypertide prices cold email inboxes one by one, on Google and Microsoft.
