Mailforge Review 2026
Last reviewed October 2026 by Théo Pascard
Mailforge
Shared-IP cold email domains and mailboxes from the Salesforge Forge family
Overview
Mailforge sells domains and mailboxes set up for cold email. The vendor calls it distributed infrastructure: your mailboxes share an IP pool with other businesses, in the way Gmail or Outlook accounts do. It automates DNS records (SPF, DKIM, DMARC), updates DNS in bulk, and offers pre-warmed domains and mailboxes. You buy mailbox slots, 10 at minimum, plus .com domains at 14 USD a year. It works with any sending software. Mailforge is one of the Forge products that G2 lists under the seller Salesforge, next to Infraforge (dedicated IPs), Primeforge (Google and Microsoft mailboxes) and Warmforge. The vendor states that more than 10,000 businesses use it, from solo senders to Fortune 500 companies.

Are Mailforge mailboxes Google or Microsoft mailboxes?
The site does not say so. It describes Mailforge as distributed infrastructure on a shared IP pool. Buyers who want Google or Microsoft mailboxes are sent to Primeforge, which the site describes as Google or Microsoft mailboxes on US IPs. If your market filters hard on sender infrastructure, test placement on a small batch before you scale.
Is there a free trial or a contract?
There is no free trial. The vendor says you must buy domains and mailboxes to use the product, although you can open the app without any. There is no contract, and you can cancel any time. At the moment each Forge product is subscribed to separately.
