Mailreef offers standard Google Workspace cold email infrastructure. Infraforge provides dedicated IPs. Here is when each wins for cold email teams.
Mailreef vs Infraforge: Two Different Infrastructure Models
Mailreef and Infraforge represent different philosophies in cold email infrastructure. Mailreef offers standard Google Workspace inboxes. Infraforge provides dedicated IP sending infrastructure. For cold email teams choosing between them, the decision depends on volume and technical capability.
| Feature | Puzzle Inbox | Infraforge |
|---|---|---|
| Infrastructure type | Google Workspace | Dedicated IPs |
| IP reputation | Inherited from Google | Self-built |
| Setup time | 24-72 hours | 1-2 weeks |
| Starting price | $3-5/inbox | $500-2,000/month |
| Deliverability out of box | Good | Poor (warming) |
| Technical complexity | Low | High |
| Volume fit | Any volume | High volume (50K+/day) |
Infrastructure Philosophy
Mailreef: Google Workspace inbox provisioning. You inherit Google's IP reputation (very high). Setup is fast, deliverability is predictable.
Infraforge: Dedicated IP sending. Your reputation is entirely your responsibility. Full control but starting at zero reputation.
Cost Comparison
For 50 cold email inboxes:
- Mailreef: 50 × $4 = $200/month + warmup ~$1,000 = $1,200/month
- Infraforge: $800-1,500/month for dedicated IPs, setup and configuration additional
At moderate volume, Mailreef is cheaper. At extreme high volume (100K+ emails/day), Infraforge dedicated IPs may have better reputation economics.
Deliverability
Mailreef leveraging Google IPs: Reply rate 2-3%, good out-of-box deliverability.
Infraforge dedicated IPs after proper warmup: Reply rate 3-4% at high volume, poor during 4-week warming phase.
When Mailreef Wins
- Most cold email operations (under 50K emails/day)
- Teams wanting fast setup and predictable deliverability
- Operations without dedicated deliverability engineering
When Infraforge Wins
- High-volume cold email programs (100K+ daily sends)
- Teams with technical deliverability resources
- Organizations with compliance requirements for private infrastructure
