On this page
Infraforge charges $4 per mailbox slot a month on quarterly billing, falling to $3 above 1,000 add-on slots, or about $3.33 a month on yearly billing. The minimum is 10 slots. Warm-up and sending are not in the price: they are separate Forge products (Warmforge and Salesforge) or another tool. Domains are $14 a year, and dedicated IPs beyond the included setup are $99 each a month, billed quarterly.
Prices below are from infraforge.ai/pricing and the plan calculator on that page, checked September 28, 2026.
Infraforge Plans and Prices
Infraforge sells one product, private SMTP mailboxes on dedicated servers, priced per slot. There is no monthly billing option on the pricing page: you pay quarterly or yearly.
Add-on slots | Quarterly billing (per slot) | Per month | Yearly billing (per slot) | Per month |
|---|---|---|---|---|
1–100 | $12 a quarter | $4.00 | $40 a year | $3.33 |
101–200 | $11.70 | $3.90 | $39 | $3.25 |
301–400 | $11.10 | $3.70 | $37 | $3.08 |
901–1,000 | $9.30 | $3.10 | $31 | $2.58 |
1,001+ | $9 | $3.00 | $30 | $2.50 |
How the tiers work, per the calculator: the first 10 slots are always billed at the top price, and the number of slots above 10 sets the tier for the rest. You pay for slots, not for mailboxes in use: "If you purchase 10 slots but only create 5 mailboxes, you are still charged for all 10 slots." Yearly billing gives "2 months free" on mailboxes; there is no discount on domains.
What the Slot Price Includes
Private SMTP mailboxes on dedicated servers and IPs. Infraforge does not sell Google Workspace or Microsoft 365; those are Primeforge, a separate Forge product.
Automated DNS setup (SPF, DKIM, DMARC).
Inbox hosting and maintenance, and support.
Access to the Infraforge API.
Not included: warm-up, a sending engine and placement tests. The pricing FAQ also says each Forge product is a separate subscription: "At the moment, you will need to subscribe to each product you want to use separately."

There is no free trial. You can cancel any time; the pricing page does not state a refund policy.
What Infraforge Costs at 25, 100 and 400 Mailboxes
Monthly cost on quarterly billing, from the slot tiers above. The full setup adds warm-up and a sending engine: we use the cheapest Instantly plan that covers 550 cold emails per mailbox a month (25 a day on 22 working days), because Instantly includes warm-up in the plan. That is the same model as our provider comparison. Domains are left out.
Mailboxes | Infraforge slots | + Instantly plan | Full setup | Outreach2day, all in |
|---|---|---|---|---|
25 | $100 | Hypergrowth $97 | $197 | $62.50 |
100 | $400 | Hypergrowth $97 | $497 | $250 |
400 | $1,483 | Hypergrowth + add-on $184 | $1,667 | $1,000 |
With Warmforge instead of Instantly warm-up, add its per-slot price (at 25 slots, $11 a month billed monthly or $9 billed quarterly), unless you send through Salesforge, which includes Warmforge. On yearly billing the slot cost drops by a sixth ($83 a month for 25 slots on the calculator).
Infraforge vs Outreach2day
Outreach2day charges $2.50 per mailbox a month with warm-up and a sending engine (campaigns, sequences, one inbox for replies) included, from 12 mailboxes, billed monthly. Domains are $13 a year for a .com and $5 for a .info. See pricing.
At every size in the table, the full setup costs less with us: $250 against $497 at 100 mailboxes. Differences to know: Infraforge sells dedicated IPs and a white-label reseller program; our mailboxes are SMTP/IMAP mailboxes on your domains, with warm-up and sending included. For every provider scored on the same rules, see cold email infrastructure providers compared.
FAQ
How much does Infraforge cost per mailbox?
$4 a month per slot on quarterly billing for up to 110 slots, falling by $0.10 a month per 100 extra slots to $3 above 1,000 add-on slots. Yearly billing is $40 per slot a year (about $3.33 a month), down to $30.
Does Infraforge include warm-up?
No. Warm-up is Warmforge, a separate product. Warmforge's page lists $12 per slot a month on monthly billing and $10 on quarterly billing for up to 10 slots, less at higher volumes, and says Salesforge users get unlimited Warmforge slots.
Is there a free trial or monthly billing?
No. Infraforge says it has no free trial because you have to buy domains and mailboxes to use it, though you can explore the app after signing up. The pricing page offers quarterly and yearly billing only. There is no contract, and you can cancel any time.
How much are Infraforge domains?
$14 a year for a .com. You get full DNS control, "the same as if you had purchased from another registrar."
