Infrastructure Differences

MailDeck: Dedicated Microsoft 365 Tenants

MailDeck provisions a dedicated Microsoft 365 tenant for each domain. Each tenant includes 100 Outlook inboxes with automated DNS configuration (SPF, DKIM, DMARC). Your emails send through Microsoft's servers with Microsoft's sender reputation.

This matters most when your recipients are enterprise companies using Microsoft Exchange. Microsoft-to-Microsoft email receives higher trust from corporate spam filters. For DNS details, see our SPF, DKIM, DMARC setup guide.

Primeforge: Google and Microsoft Mailboxes

Primeforge provides individual Google Workspace and Microsoft 365 mailboxes with automated DNS setup. They offer pre-warmed mailboxes for faster time-to-send.

This matters if you need instant setup, pre-warmed mailboxes, or balanced focus across both Google and Microsoft.

Where MailDeck Falls Short

To give you an honest comparison, here's where Primeforge has advantages:

Setup speed. Primeforge delivers mailboxes in approximately 30 minutes. MailDeck takes 48 hours to provision Microsoft 365 tenants. If you need inboxes today, Primeforge wins.

Lower entry point. Primeforge allows purchasing individual mailboxes. For small tests or solo operations, Primeforge is more accessible.

Pre-warmed mailboxes. Primeforge offers pre-warmed mailboxes ready immediately. MailDeck's Microsoft 365 tenants inherit Microsoft's reputation, but we still recommend 3-7 days of gradual volume increase.

Google Workspace focus. Primeforge offers both Google Workspace and Microsoft 365 with equal focus. MailDeck also supports both, but our primary focus and strongest infrastructure is Microsoft 365. If Google Workspace is your priority, Primeforge may offer a better fit.

Infrastructure only. MailDeck does not include a sequencer. You'll need Instantly, Smartlead, or similar separately.

Where MailDeck Wins

Dramatically lower cost at scale. At 1,000 SMTP inboxes, MailDeck costs $450/month vs Primeforge's approximately $4,500/month. That's 10x less, saving $48,600/year.

Dedicated infrastructure. Each MailDeck domain gets its own Microsoft 365 tenant. Your domains are fully isolated from other customers.

Transparent pricing. MailDeck pricing is published and transparent — from $0.40/inbox (SMTP) to $3.50/inbox (Google Workspace). No calculator needed.

Enterprise deliverability. Microsoft 365 infrastructure has the highest trust with corporate mail servers. We maintain 98% inbox placement across 650K+ managed Outlook inboxes.

Simpler scaling. Multiple products to fit your needs — SMTP, Google Workspace, and Outlook tenants. Scale up easily. To plan capacity, see our inbox calculator.
