Primeforge lists $4.50 per mailbox. Your real bill depends on four things that headline price hides: the 10-slot minimum, domain fees, your billing cycle and what you pay for warmup.
This guide turns the price list into a monthly total for 10, 25, 50 and 100 mailboxes, shows what is included and what costs extra, and explains when a different setup may fit better.
Short answer: Primeforge charges $4.50 per mailbox slot per month, or about $3.75 with annual billing (two months free), with a 10-slot minimum. Domains cost $14 a year each. For 25 mailboxes with three per domain, expect about $104 a month on annual billing or $123 on monthly billing, domains included.
How much does Primeforge cost per mailbox?
Primeforge's pricing calculator shows $4.50 per mailbox slot per month. Annual billing gives two months free, which works out to about $3.75 per slot per month. There is a minimum of 10 slots.
Here is the mailbox cost at the listed rate (estimates, domains not included):
Mailboxes | Monthly billing | Annual billing (per month) | Annual billing (per year) |
|---|---|---|---|
10 | $45 | $37.50 | $450 |
25 | $112.50 | $93.75 | $1,125 |
50 | $225 | $187.50 | $2,250 |
100 | $450 | $375 | $4,500 |
At 25 mailboxes, Primeforge's own calculator shows $94 a month billed yearly and $113 billed monthly, which matches the table.
You will see other numbers online. Some Primeforge and third-party pages quote $3.50 to $4.50 per mailbox depending on volume, and an older third-party page lists $5.40 on monthly billing. Prices change, so confirm bulk pricing in the calculator on the day you buy.
How much do Primeforge domains cost?
Domains are billed separately at $14 per year for each .com domain, charged once a year. There is no annual discount on domains.
Primeforge's calculator assumes three mailboxes per domain and recommends two to three per domain for the best deliverability, with about 30 emails per mailbox per day (100 at most). If you already own domains, you can connect them from any registrar by updating nameservers, so you only pay for mailboxes on those domains.
Mailboxes | Domains needed (3 per domain) | Domain cost per year | Domain cost per month |
|---|---|---|---|
10 | 4 | $56 | $4.67 |
25 | 9 | $126 | $10.50 |
50 | 17 | $238 | $19.83 |
100 | 34 | $476 | $39.67 |
The 25-mailbox row matches Primeforge's calculator: nine domains, $126 a year.
What is the real monthly total?
Add mailboxes and domains together. This table uses the listed $4.50 monthly rate, the $3.75 annual rate and the domain costs above (all estimates):
Mailboxes | Annual billing, per month | Monthly billing, per month |
|---|---|---|
10 | about $42 | about $50 |
25 | about $104 | about $123 |
50 | about $207 | about $245 |
100 | about $415 | about $490 |
Formula to estimate your own bill:
Mailboxes: slots × $4.50 (monthly) or slots × $3.75 (annual)
Domains: mailboxes ÷ 3 × $14 ÷ 12
Add warmup and your sending tool if they are not already covered

How does Primeforge billing work?
Monthly or annual: Annual billing for mailboxes gives two months free. Domains get no discount.
Slots, not active mailboxes: You pay for every slot you buy, even if you create fewer mailboxes. You can delete and recreate mailboxes inside your slots at no extra cost.
No contract: Primeforge says you can cancel anytime.
No free trial: You buy domains and mailboxes to use it, though you can explore the app first.
Invoices: You receive an invoice for each purchase.
What is included, and what costs extra?
Item | Status |
|---|---|
Automated DNS setup (SPF, DKIM, DMARC) | Included |
Mailbox hosting and maintenance | Included |
Expert customer support | Included |
API access | Included |
Domains | Extra, $14 per year each |
Ongoing warmup | Extra: Primeforge's own comparison page says warmup is available through Warmforge, charged separately |
Sequencer for sending | Not included |
Warmup is the cost to watch. Primeforge sells a pre-warmed option and says warmup is completed before delivery. Its pre-warmed page shows no separate price, and Warmforge says there is no extra fee, so confirm at checkout whether pre-warmed mailboxes cost more. Ongoing warmup after delivery is a separate matter. Warmforge's own pages list standalone slots at about $9 to $12 per mailbox per month depending on billing, and say warmup is included with a Salesforge subscription. At $10 a slot, 25 mailboxes would add about $250 a month (estimate). Many sequencers also include warmup, so check yours before paying twice.
Who is Primeforge pricing a good fit for?
A good fit if you:
Run 20 or more mailboxes and can use a 10-slot minimum.
Want real Google Workspace and Microsoft 365 mailboxes so you can send from the same provider your prospects use.
Already use Salesforge, where Warmforge warmup is included.
Own domains and want to connect them for free.
A weaker fit if you:
Need fewer than 10 mailboxes, since you still pay for 10 slots.
Want a free trial before spending anything.
Want domains and warmup history in one bundled monthly price.
How does Primeforge compare with LiteMail on price and mailbox type?
Both sell real Google Workspace and Microsoft 365 mailboxes. The pricing models differ.
Primeforge | LiteMail | |
|---|---|---|
Mailbox types | Google Workspace and Microsoft 365 | Google Workspace and Microsoft 365 |
Entry price | $4.50 per slot, 10-slot minimum ($45 a month) | Pre-warmed from $39 a month for 5 mailboxes with 1 domain included; fresh from $37 a month for 10 |
Domains | $14 per year each, billed separately | Included in pre-warmed plans; $15 per year for fresh |
Warmup | Pre-warmed option; ongoing warmup billed separately | Sending history built in on pre-warmed plans |
Billing | Monthly, or annual with two months free | Monthly plans |
Free trial | No | No refunds, so start small |
Blacklisted domain | Not stated on the pricing page | Replaced at no extra cost |
At 30 mailboxes (estimates): Primeforge costs about $124 a month on annual billing, or $147 on monthly billing, with 10 domains. LiteMail's pre-warmed Pro plan is $179 a month with 30 mailboxes and 6 domains. Primeforge is the lower sticker price at this size. LiteMail's value is the bundle and the plan structure, not the lowest cost. Prices change, so confirm both before buying.

When does LiteMail make more sense than Primeforge?
We sell inboxes, so weigh this section accordingly. LiteMail is worth a look in these cases:
You want one bundled price. Pre-warmed plans start at $39 a month for 5 mailboxes with a domain included. Growth is $99 for 15 mailboxes and 3 domains, and Pro is $179 for 30 mailboxes and 6 domains. There is no separate domain bill.
You need fewer than 10 mailboxes. Primeforge sells a minimum of 10 slots. LiteMail's pre-warmed Starter plan begins at 5 mailboxes.
You want a second provider. Primeforge's own pricing page recommends combining its mailboxes with its sister products, and says using two or more infrastructure providers reduces the risk of burn. LiteMail can be that second provider, with Google Workspace and Microsoft 365 inboxes.
You want blacklisted domains replaced. LiteMail replaces a blacklisted domain on pre-warmed plans at no extra cost. See our pre-warmed domains.
You want official accounts with full admin access. LiteMail sets up SPF, DKIM and DMARC automatically on US and EU IPs.
One difference to weigh: LiteMail's pre-warmed plans bundle about five mailboxes per domain, while Primeforge's calculator suggests two to three. Pick the ratio that matches your risk tolerance.
How we help you start:
Estimate your mailbox count with the calculator.
Choose between fresh and pre-warmed. Our pre-warmed vs fresh guide explains the trade-off.
Start with the smallest plan, since LiteMail does not offer refunds.
Connect the inboxes to your sequencer, then add a second provider or more mailboxes as you scale.
Final take
Primeforge's real cost is about $42 a month for 10 mailboxes and $104 for 25 on annual billing, once you add domains. Add warmup if you need it. It is a strong price for teams running 20 or more mailboxes. If you need a smaller start, a bundled price or a second provider, compare it with LiteMail before you commit.
