About

What is Infraforge

Infraforge gives you private cold email infrastructure built on dedicated IP addresses — you provision unlimited domains and mailboxes, automate SPF, DKIM, and DMARC setup, and run warmup without touching a third-party shared pool. It's built for SDRs, BDRs, agencies, and founders who need full ownership of their sending environment rather than renting space on someone else's IP reputation. The standout capability is pre-warmed domain and mailbox provisioning: you can spin up ready-to-send infrastructure without the manual ramp period that kills most cold outreach timelines. It connects to sending tools via API and supports multiple workspaces, making it workable for agencies managing several clients. That said, Infraforge is infrastructure, not a sequencer — if you need campaign logic, A/B testing, or reply handling, you'll need a separate sending tool on top.

Our verdict

Vanderbuild take

For SDRs, agency operators, and founders who've been burned by shared IP deliverability problems, Infraforge is a straightforward answer: you own the infrastructure, the IPs, and the reputation. The API exists and you can connect it to your sending stack, but agentic readiness is limited — don't expect to build a fully autonomous outbound loop on top of it without hitting friction in what the API actually exposes. Pricing starts at $4/mailbox/month with usage-based billing, which makes it low-risk to test at small scale, though costs compound quickly once you're running dozens of domains across multiple client workspaces. The honest gap here is that Infraforge stops at the infrastructure layer — sequencing, personalization, and reply management all live elsewhere, so budget for the full stack before assuming this solves your deliverability end-to-end.
