Book a DemoSmartInfra is Smartlead's privatised email sending infrastructure that gives you dedicated servers and IP pools for your outreach campaigns.
It is built for teams that need an added layer of control over their sending environment, with full ownership over server reputation, IP management, and inbox placement at scale.
SmartInfra is designed for high-volume senders, enterprises, and agencies that need full control over their sending infrastructure and cannot afford deliverability issues.
SmartInfra uses multi-server clusters to spread campaign traffic across dedicated IP pools, preventing any single campaign from affecting others. Each sequence is isolated in single-tenant clusters, eliminating cross-domain interference.

Yes. Smartlead allows agencies to assign dedicated servers to individual clients, ensuring each client's sending infrastructure is fully isolated from others. This means one client's campaign performance or reputation issues cannot affect another client's deliverability within the same agency account.
