Primeforge
Cold email mailboxes, ready to send.
What is Primeforge
Primeforge provisions Google and Microsoft mailboxes specifically configured for cold outreach, handling DNS records, mailbox slots, and US-based IP addresses so teams don't have to manage infrastructure manually. It's built for SDRs, BDRs, and GTM engineers at SMB and mid-market companies who run outbound at volume and need reliable inbox placement without manual configuration overhead. The standout capability is bulk DNS updates across multiple workspaces — meaning you can spin up or reconfigure sending infrastructure at scale without touching each domain individually. Primeforge sits within the Forge Stack ecosystem, so it connects naturally with Salesforge, Mailforge, and Leadsforge, but teams running outside that stack may find native integrations limited. If your outbound motion lives entirely in a non-Forge toolchain, you'll need to rely on the API to bridge the gap.

Vanderbuild take
Primeforge is a cold email infrastructure tool — not a sequencer, not a CRM — and for SDRs and GTM engineers who need to stand up sending domains fast without babysitting DNS records, it does that job cleanly. The agentic story here is real: native MCP server support means you can wire Primeforge directly into an AI agent orchestration layer, making it one of the few deliverability infrastructure tools that's genuinely agent-callable out of the box. Pricing isn't publicly listed, so you'll need to go through their sales flow to size the cost — that's a friction point worth noting before you build it into a budget. The honest limitation is ecosystem lock-in: Primeforge integrates tightly with the Forge Stack (Salesforge, Mailforge, Leadsforge), and teams running a different outbound stack will be leaning on the API rather than native connectors.
Agentic stack profile
MCP serverYesLive MCP server — agents can call this tool directly.
The Forge MCP Server enables AI agents to create domains, provision Google Workspace and Microsoft 365 mailboxes, configure DNS settings, and monitor warmup/placement data.
Open MCP →APIRESTProgrammatic access available.
REST API — straightforward to call from any agent or workflow tool. Rate limits and auth vary by plan.
Agentic readinessNativeBuilt for agents from the ground up.
MCP server + agent-friendly API + at least one autonomous workflow out of the box. The bar for 'Native' is high — only a handful of tools currently qualify.
