Partner disclosure: Arrel partners with Mailpool and may benefit commercially if you choose it. We applied the same official-source standard to both products, show where Primeforge costs less and link the current pricing so you can check our work.
Our short answer: Mailpool is the more flexible starting point. It sells its own managed inboxes for $3 per month, Google for $4, Microsoft for $5 and a dedicated server from $200. Primeforge sells Google and Microsoft mailbox slots for $4.50 per month, with a ten-slot minimum. Primeforge makes more sense when your team already uses Salesforge or Warmforge. Mailpool makes more sense when you want several infrastructure types in one account or fewer than ten inboxes.
| Decision | Mailpool | Primeforge |
|---|---|---|
| Monthly mailbox price | Mailpool $3; Google $4; Microsoft $5 | $4.50 per Google or Microsoft mailbox slot |
| Annual equivalent | $2.60; $3.40; $4.30 respectively | About $3.75 per slot after two months free |
| Minimum | One mailbox | Ten mailbox slots |
| Providers | Managed shared, Google, Microsoft and dedicated | Google Workspace and Microsoft 365 |
| .com domain | Price shown at checkout for a one-year registration | $14 per year |
Mailbox slots are capacity. Primeforge charges for all ten slots even if you create only six inboxes. Mailpool publishes no comparable minimum. Both companies offer custom terms at volume, so public list prices may stop describing your invoice once you manage hundreds of accounts.
The cheaper provider changes with the inbox type
Ten Google inboxes cost $40 per month on Mailpool and $45 on Primeforge. With annual billing, the effective monthly figures are $34 and $37.50. Mailpool has the lower Google price at this small size.
Microsoft reverses that result. Ten Microsoft inboxes cost $50 monthly on Mailpool and $45 on Primeforge. Annual equivalents are $43 and $37.50. Primeforge wins that narrow price comparison, provided you need at least ten slots. A buyer who needs three Microsoft accounts would still spend less in total on Mailpool because Primeforge's minimum sets the floor at $45 monthly.
Domain charges belong in the same model. Primeforge publishes a $14 annual price for a .com. Mailpool registers domains for one-year terms but shows the price during checkout rather than on its pricing page. Ask both vendors for the same domain list before comparing totals.
Mailpool offers more ways to spread infrastructure
Mailpool can put inboxes on its managed rotating network, Google Workspace, Microsoft 365 or a dedicated server. That gives an operator one place to test a provider mix and avoid depending on a single mailbox type. Its dedicated server costs $200 monthly or $170 on annual billing, although Mailpool also charges for send volume and does not publish that rate. Request an all-in quote before using the dedicated headline in a forecast.
Primeforge concentrates on Google and Microsoft business inboxes with US-based IPs. It configures SPF, DKIM and DMARC, hosts the mailboxes and lets you bring existing domains. The narrower choice may suit a team that wants official provider accounts and already understands which mix it needs.
Pick Mailpool
Start small or mix providers
You need fewer than ten inboxes, want Mailpool's lower-cost managed option, or plan to combine shared, Google, Microsoft and dedicated infrastructure.
Pick Primeforge
Stay inside the Forge workflow
You want Google or Microsoft inboxes, the ten-slot minimum works, and Salesforge or Warmforge already handles the next stage of your process.
Automation is available on both sides
Mailpool's API can buy and configure domains, create batches of mailboxes, update DNS and inspect mailbox status. Its workspace model separates clients or business units, and invited team members do not need individual subscriptions. Owner, Admin and Member roles control access.
Primeforge also publishes an API for workspaces, domain search and purchase, mailbox creation, DNS checks and exports. Multiple workspaces can separate clients. The pricing page includes API access with the subscription, although account permissions may determine who can create a key.
Neither subscription includes your campaign engine
These products build the sending infrastructure. You still need a sequencer to schedule messages, run follow-ups and manage replies. Primeforge hands inboxes to Salesforge or another compatible sender. Warmforge is a separate warmup layer. Some Primeforge articles describe a close Warmforge integration, but the base pricing page does not price warmup as part of the mailbox subscription. Confirm the exact bundle before counting it as included.
Mailpool exports inboxes to sending and warmup tools. Its own pricing does not include sequence capacity, lead storage or campaign sends. Add the sequencer, warmup, domains, monitoring and replacement policy to the total cost for either vendor.
