Most cold email platforms put you on shared IP pools. outinfra gives every domain its own sovereign infrastructure stack — dedicated IPs, dedicated resources, dedicated reputation.
When you send from a shared IP pool, your deliverability depends on the behavior of every other sender on that pool. One spam campaign by another tenant can blacklist the IP for everyone. One account hitting spam traps tanks the pool's reputation. You have zero control.
Most "dedicated IP" claims from email infrastructure providers are actually semi-shared pools — you share an IP range with hundreds of other senders. True isolation requires a dedicated resource at the provider level, not just an IP allocation.
outinfra provisions a separate Azure Communication Services resource per domain. That resource has its own IP, its own identity, its own sending history. When you join outinfra, you're not borrowing an IP — you own the sending resource.
outinfra runs across three infrastructure tiers to ensure continuity, diversification, and maximum deliverability coverage.
Primary infrastructure tier. Every provisioned domain gets its own Azure Communication Services resource with a dedicated Microsoft enterprise IP. Highest deliverability trust scores available.
Scale tier for high-volume provisioning. Microsoft 365 mailboxes provisioned via Pax8 CSP (Cloud Solution Provider). Used when ACS capacity constraints apply or when M365 native mailboxes are required.
Provider diversification tier. Google Workspace mailboxes provisioned via a GWS sub-reseller. Used for campaigns that benefit from Google's sender infrastructure or for diversifying across providers.
All DNS management runs through Cloudflare. When a domain is provisioned, outinfra creates a Cloudflare zone, updates nameservers, and sets every required DNS record via the Cloudflare API — with zero manual intervention.
Cloudflare's global Anycast network ensures DNS propagation happens in minutes, not hours. The platform verifies propagation across multiple global resolvers before advancing to the next pipeline stage.
Stop sharing IP pools with strangers. Get dedicated Microsoft enterprise IPs for every domain you own.
