Why Teams Switch from Infraforge to MailDeck
1. 6x Lower Cost at Scale
Infraforge charges $3-4 per mailbox. That adds up fast.
At 200 mailboxes, you're paying $650/month with Infraforge.
MailDeck charges per domain, and each domain includes 100 inboxes. The same 200 inboxes costs $99-110/month.
| Scale | Infraforge | MailDeck | You Save |
|---|---|---|---|
| 200 inboxes | $650/mo | $110/mo | $540/mo |
| 500 inboxes | $1,750/mo | $275/mo | $1,475/mo |
| 1,000 inboxes | $3,500/mo | $500/mo | $3,000/mo |
At 1,000 inboxes, you save $36,000/year with MailDeck.
2. Native Microsoft 365 Infrastructure
Infraforge uses private SMTP servers with dedicated IPs.
MailDeck provides native Microsoft 365 Outlook tenants. This is the same infrastructure Fortune 500 companies use for email.
Why this matters:
- Microsoft's sender reputation backs every email you send
- Clean headers with no "cold email infrastructure" fingerprint
- Higher inbox placement with enterprise recipients
3. 98% Deliverability
We maintain 98% deliverability across all MailDeck tenants. Your emails land in primary inbox.
4. Simple Scaling Model
- 1 domain = 1 tenant = 100 inboxes
- 50 emails per inbox per day (safe sending limits)
- 150,000 emails per month per domain
Need to send 1.5M emails/month? Add 10 domains. Done.
MailDeck Pricing

| Growth | $50/mo per domain | 11-30 | 1,100-3,000 |
| Enterprise | $45/mo per domain | 31-100 | 3,100-10,000 |

Each domain includes automated DNS configuration (SPF, DKIM, DMARC) and deliverability monitoring.
Who is MailDeck For?
MailDeck is built for high-volume cold email operations:
- Lead generation agencies scaling past 100k emails/month
- B2B SaaS companies with dedicated outbound teams
- SDR teams sending at enterprise scale
- Recruitment firms with high-volume outreach
If you're sending less than 30,000 emails/month, Infraforge might be enough. Once you scale, the per-mailbox pricing becomes a bottleneck.
