Company Overview and information
What is Mission Inbox?
Mission Inbox is an Email Infrastructure-as-a-Service (IaaS) platform that provides isolated, AI-protected servers with dedicated IPs for all email workloads. Unlike legacy email service providers (ESPs) that mix customer emails on shared IP pools, Mission Inbox gives each customer their own dedicated infrastructure, ensuring their email reputation is entirely under their control.
