Primeforge review (2026): pricing, pros and cons, alternatives

What Primeforge is

Primeforge is the Google Workspace and Microsoft 365 product in the Salesforge family, which also includes the Salesforge sequencer, Mailforge for shared-pool mailboxes, Infraforge for private servers with dedicated IPs and Warmforge for warmup. Where its siblings run their own infrastructure, Primeforge provisions real Google and Microsoft accounts on domains you buy in the app or connect from any registrar, with one Microsoft 365 tenant per domain. The pitch is ESP matching: send from the same provider your prospect uses and you are more likely to land in the primary inbox.

The company’s own advice is to mix. Its pricing page recommends combining Primeforge with Mailforge or Infraforge so that there is always a mailbox on the same provider as the recipient, and so that one provider’s bad week does not take down all of your sending.

Primeforge pricing

Everything is sold in slots, with a minimum of 10, billed monthly or yearly. On monthly billing a slot costs $4.50 a month for the first 100 add-on slots above the base 10, stepping down by 10 cents per hundred slots to $3.50 past 1,000. On yearly billing a slot costs $45 a year, or $3.75 a month, stepping down by a dollar a year per hundred slots to $35, or $2.92 a month, past 1,000. The yearly rate is the two-months-free discount mentioned in the FAQ, and the pricing page gives one slot price whether you choose Google or Microsoft.

Domains cost $14 a year for a .com, charged yearly with no discount, and connecting domains you already own is free: point their nameservers at Primeforge and it writes the records. The calculator on the pricing page shows the arithmetic at its defaults: 25 slots come to $113 a month billed monthly or $94 billed yearly, plus 9 domains at $126 a year. Ten slots, the minimum, cost $45 a month or $450 a year before domains.

The terms match the rest of the family. Plans renew automatically, cancellation must be filed at least 7 days before the term ends and only through live chat, prepaid fees are not refunded, and prices can change on 30 days of notice. There is no free trial, although you can look around the app without buying anything.

Setup and integrations

Setup is self-serve and automated: buy or connect a domain and SPF, DKIM and DMARC are written for you, DNS can be edited in bulk across every domain, mailboxes and domains can be moved between workspaces, and there is an API. The site does not publish how long a Google or Microsoft mailbox takes to arrive. Mailboxes work with Salesforge natively and with any other sending software. Warmup is not included: Warmforge, the family’s warmup product, lists $10 a slot a month with one free slot, and Primeforge also sells pre-warmed mailboxes at prices not shown on the site.

Deliverability

Because these are Google and Microsoft accounts, they start with the reputation those providers lend their own tenants, which is the strongest argument for Primeforge over the family’s SMTP products. One Microsoft tenant per domain means a problem on one domain does not spread to the others. The sending guidance is the usual: 30 emails a day per mailbox, 100 at most, and two or three mailboxes per domain. Beyond that the site makes few claims, which is to its credit.

Who Primeforge is for, and who should look elsewhere

Primeforge suits teams already in the Salesforge stack and agencies that want self-serve Google and Microsoft accounts with slots, workspaces and an API. It is a poor fit for anyone shopping on price per mailbox, for teams that want warmup and setup done for them, and for orders under 10 mailboxes. Zapmail sells Google and Microsoft inboxes with a cheaper entry point, Premium Inboxes resells both on a monthly plan, and Hypertide automates Google inboxes with no minimum and Microsoft Entra domains at about $1 an inbox. The inbox provider comparison scores all of them. The sequencer side of the family is reviewed at Salesforge.

Where PureMail is cheaper, and where Primeforge wins

Google Workspace and Microsoft 365 inboxes set up by PureMail cost $3.30 each for 10, $3.10 for 30 to 100 and $2.90 for 101 or more, billed monthly, with SPF, DKIM, DMARC and MX configured and the sequencer connected in about four hours. Ten inboxes cost $33 a month against Primeforge’s $45 a month, or $37.50 a month with a year paid up front. A hundred cost $310 against $450 or $375. At 1,100, where Primeforge’s yearly tiers bottom out, PureMail is still $3,190 a month against $3,217. Full details are on the pricing page.

Primeforge wins on control: a self-serve app, slots you can reuse as domains burn out, bulk DNS, a workspace per client, an API, domain purchase in the app, and a family of sibling products for mixing providers and buying pre-warmed mailboxes. If you already run Salesforge and value that automation over the lowest price, it fits. The table below puts the two side by side.
