Mailforge sells SMTP mailboxes on a shared IP pool, priced as slots. PureMail sets up real Google Workspace and Microsoft 365 inboxes on your own domains and connects them to your sequencer, for less than Mailforge’s own company charges for that kind of inbox. Here is how the two kinds of cold email infrastructure compare.

Mailforge only fits if
Mailforge does not sell Google or Microsoft inboxes at all. Its company sells those separately as Primeforge, at $4.50 a slot, and PureMail costs up to 34% less at every size. Mailforge’s cheaper slots are a different product: SMTP on a shared IP pool instead of Google’s or Microsoft’s own servers.

Price
Mailforge pricing is per SMTP slot, with a 10-slot minimum. The same company sells its Google and Microsoft mailboxes as Primeforge, from $4.50 a slot, so that is the like-for-like price, and PureMail is lower at every size from 10 to 1,000. Switch the slider to see the SMTP slots too.

Mailbox type
This is the difference that matters more than the price. A Mailforge mailbox is an SMTP account on the company’s own servers. Your messages leave from a pool of IP addresses shared with its other customers, so you share the pool’s reputation with everyone on it. The company says so plainly, and recommends the shared pool for senders who expect a high rate of spam complaints.
A PureMail inbox is a Google Workspace or Microsoft 365 account on your domain. It sends through Gmail’s or Outlook’s own infrastructure, the same way your prospects’ colleagues email them, so it starts with the reputation those providers give their own customers. For a list that reads mail in Gmail or Outlook, that is the closest match you can buy.
The same company sells real Google and Microsoft accounts too, under a different name: Primeforge, at $4.50 a slot monthly. Mailforge vs Primeforge is SMTP vs Google and Microsoft cold email infrastructure. PureMail is on the Google and Microsoft side of that line, for up to 34% less.
PureMail is a reseller for both. See our Google Workspace reseller inboxes and Microsoft 365 reseller inboxes for cold email.

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, which all the major tools include, 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: add a domain and it writes SPF, DKIM, DMARC and a tracking domain, then you create the mailboxes and connect each one to your sequencer over SMTP and IMAP yourself.
Warmup is not included. It points you to Warmforge, a separate product listed at $10 a slot a month with one free slot, or you warm up in your sequencer. Its guidance is 30 emails a day per mailbox and two or three mailboxes per domain.
Why switch
What changes when you move from shared SMTP slots to Google Workspace and Microsoft 365 inboxes set up for you.
Every inbox sends from Google’s or Microsoft’s own servers, the providers your prospects read mail in, instead of an IP pool shared with other senders.
Primeforge, the same company’s Google and Microsoft product, is $4.50 a slot. PureMail is $3.30 to $2.90 an inbox.
We write the DNS, create every inbox and connect it to your sequencer. You never touch a DNS record.
Pay monthly per inbox and cancel from your dashboard. No yearly prepayment, no 7-day live-chat notice.

FAQ
Is Mailforge good, what it costs, and how to move across.
01
Yes, it is a real product from the company behind Salesforge, with public pricing and terms. The real question is what it sells: SMTP mailboxes on a shared IP pool, not Google Workspace or Microsoft 365 accounts. If your prospects read mail in Gmail or Outlook, that difference matters more than the slot price.
02
It depends on what you need from a mailbox. At $3 a slot it is cheap SMTP, but you share an IP pool, set up and connect everything yourself, pay for Warmforge separately if you want its warmup, and cancel only through live chat a week before renewal. If you want Google or Microsoft inboxes, PureMail costs less than the same company’s own Google and Microsoft product and does the setup for you.
03
No, there is no free trial; you can look around the app without buying slots or domains. Plans start at 10 slots, billed monthly or yearly, and prepaid fees are not refunded.
04
No. Mailforge mailboxes are SMTP accounts on the company’s own servers and shared IP pool. The same company sells Google Workspace and Microsoft 365 accounts as a separate product, Primeforge, from $4.50 a slot. PureMail inboxes are Google Workspace or Microsoft 365 accounts from $2.90.
05
Its SMTP slots cost less per mailbox: $30 for 10 against $33, $300 for 100 against $310. But they are not the same product. For a Google Workspace or Microsoft 365 inbox, the like-for-like price is the same company’s Primeforge, and PureMail is cheaper at every size: $310 for 100 inboxes against $450.
06
Both come from the Salesforge company. Mailforge sells SMTP mailboxes on a shared IP pool from $3 a slot; Primeforge sells Google Workspace and Microsoft 365 accounts from $4.50 a slot monthly or $3.75 yearly, with the same 10-slot minimum. PureMail is the same kind of mailbox as Primeforge, from $2.90 an inbox, with setup done for you.
07
Yes. Set up PureMail inboxes on your domains, warm them up in your sequencer for two to three weeks while your current mailboxes keep sending, then move campaigns across and cancel the old slots. Remember the 7-day cancellation notice.
08
They arrive set up and connected to your sequencer, and you run its built-in warmup for two to three weeks at no extra cost. Mailforge does not include warmup either; it sells it separately as Warmforge.
