Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
1.6
GPA, above 5 of the 81 other cold outreach tools we grade
Primeforge sells domains and Google Workspace and Microsoft 365 mailboxes configured for cold outreach, so senders can match the mail provider their prospects use. It sets up DNS records automatically and hosts the mailboxes, which then connect to Salesforge or any other sending tool. It is one product in the Forge stack.
To get you started, here are 8 things to know about Primeforge, taken from its own pages and our grades.
You buy domains, set up mailboxes and connect them to a sending tool.
- 1
Best for buying Google and Microsoft mailboxes for cold email
It is only the mailboxes: you still need a separate tool such as Salesforge to send anything.
- 2
Paid plans start at $38 a month
As its pricing page puts it: $38 per month for 10 mailbox slots, billed yearly ($45 billed monthly).
- 3
It runs on Web
Web.
- 4
Google and Microsoft mailboxes
Provides Google Workspace and Microsoft 365 mailboxes, so a sender can match the provider a prospect uses, which the vendor says helps inbox placement.
- 5
Automated DNS setup
Configures DKIM, DMARC and SPF records automatically. Domains stay under your control and DNS records can still be edited.
- 6
Pre-warmed mailboxes
The vendor lists pre-warmed mailboxes that can be added to Salesforge or other sending software, with setup in about 30 minutes.
- 7
A 1.6 GPA, above 5 of 81
That is against the other cold outreach tools we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
To replace Primeforge 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.

The report card
Best for buying Google and Microsoft mailboxes for cold email
Primeforge sells domains and Google Workspace and Microsoft 365 mailboxes set up for cold outreach, with the DNS records done for you. It is only the mailboxes: you still need a separate tool such as Salesforge to send anything. There is no trial, you buy at least 10 slots, and slots are billed whether you fill them or not.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $38 a month for 10 mailbox slots on yearly billing ($45 monthly), about $4.50 a slot, plus $14 a year for each .com domain. That is the middle of the category's range before the sender you also need. |
| Free plan and trial | F | No free plan and no trial, because domains and mailboxes have to be bought first. |
| Features | D | Mailboxes, domains and DNS only. It sends no emails, finds no leads and needs another product to be useful. |
| Ease of use | C | No store rating on record. You buy domains, set up mailboxes and connect them to a sending tool. |
| Platforms and integrations | B | Web, with an API and links to the other Forge products. The listing names no wider integrations. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Primeforge is for
- Fits if you send cold email at volume and want Google or Microsoft mailboxes
- Works for teams already using Salesforge or another Forge product
Who it is not for
- Skip it if you want to test it first, as nothing is free
- Too light on its own, since you still need a separate tool to send
- Tight if you only need a few mailboxes: the minimum is 10 slots, billed even when empty
- Watch out: each Forge product is its own subscription, and domains get no yearly discount
Good to know
Good for
- Senders whose prospects mostly use Google Workspace or Microsoft 365
- Agencies running many domains and mailboxes
- Teams that already send through Salesforge or another sequencer
Worth knowing
- Primeforge sells infrastructure only: sending needs a separate tool such as Salesforge.
- No free trial is offered, because domains and mailboxes must be bought first.
- Each Forge product is a separate subscription, and domains get no annual discount.
- Slots are billed whether or not mailboxes are created, with a 10-slot minimum.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Primeforge 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: 64 of the 81 other cold outreach tools grade higher. It costs $456 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, Mailforge and Infraforge among them, and has an API.
What this rests on. Primeforge’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.
