Mailbox type
An Infraforge mailbox is an SMTP account on Infraforge’s servers, sending from IP addresses dedicated to you. That is its selling point: nobody else’s mail shares your IPs, so the reputation is yours. It also means it starts from zero, and you build it.
A PureMail inbox is a Google Workspace or Microsoft 365 account on your domain, sending through Gmail’s or Outlook’s own infrastructure, the providers your prospects read their mail in, with the reputation those providers give their own customers.
The same company sells Google and Microsoft accounts as Primeforge, at $4.50 a slot. So Infraforge vs PureMail is really a choice between private SMTP and Google and Microsoft cold email infrastructure, and between prepaying a quarter and paying monthly.
PureMail is a reseller for both. See our Google Workspace reseller inboxes and Microsoft 365 reseller inboxes for cold email.

Infraforge
Setup
You choose the inbox count, Google Workspace or Microsoft 365 (or both) and your domains. Our team writes MX, SPF, DKIM and DMARC on every domain, creates each inbox with its sender name and connects it to Instantly, Smartlead, ReachInbox or the tool you send from. A typical order is live in about four hours.
Warmup runs in your sequencer at no extra cost. Plan two to three weeks before full volume, at around 30 cold emails a day per inbox.
It is self-serve and fast: add a domain and it writes SPF, DKIM, DMARC and a tracking domain in about five minutes, with bulk DNS edits, a workspace per client, an API, a CLI and an MCP server.
Warmup is not included: it points you to Warmforge at $10 a slot a month, with one free slot. New dedicated IPs need warming as well as the mailboxes.
Why switch
Google Workspace and Microsoft 365 reputation instead of a new private IP, paid monthly, set up for you.
Inboxes send from the providers your prospects use, instead of IPs whose reputation you build from zero.
Pay one month at a time and cancel from your dashboard. No quarter or year up front.
$310 against $400 for 100, $1,450 against $1,800 for 500.
We write the DNS, create every inbox and connect it to your sequencer.

FAQ
Is Infraforge good, what it costs, and how to move across.
01
Infraforge is the Salesforge company’s private cold email infrastructure: SMTP mailbox slots on dedicated IPs, from $4 a slot a month billed quarterly or $3.33 billed yearly, with a 10-slot minimum, automated DNS, client workspaces and an API.
02
It is well built: dedicated IPs, five-minute setup and real automation. The trade-offs are that it is SMTP rather than Google or Microsoft accounts, the shortest term is a quarter paid up front and not refunded, warmup is a separate $10 a slot, and you cancel through live chat a week ahead.
03
Slots are $4 a month each on quarterly billing for the first 100, stepping down to $3 past 1,000, or $3.33 a month on yearly billing, down to $2.50. Ten slots cost $120 a quarter. Domains are $14 a year, extra IPs $99 a month and Warmforge warmup $10 a slot.
04
Not on its quarterly term: PureMail is $310 a month for 100 inboxes against $400, and $1,450 against $1,800 for 500, billed monthly. Infraforge’s yearly rate is lower past about 600 slots, for SMTP paid 12 months ahead.
05
Both are Salesforge’s SMTP products. Mailforge runs on a shared IP pool from $3 a slot, monthly or yearly; Infraforge runs on dedicated IPs from $4 a slot, quarterly or yearly. Primeforge, the third, sells Google and Microsoft accounts. PureMail is the same kind of inbox as Primeforge, from $2.90.
06
No. Infraforge bills quarterly or yearly, and prepaid fees are not refunded. PureMail bills monthly and you cancel from the dashboard.
07
Yes. Set up PureMail inboxes on your domains, warm them in your sequencer while Infraforge keeps sending, move campaigns across, then cancel through live chat at least 7 days before your term ends.
