Teams that rely on email, run on Mission Inbox. See what changed after they moved away from shared sending infrastructure.
Yes. Mission Inbox provides an email API for AI agents, applications and automated workflows. Unlike a basic sending API, it also supports receiving email, dedicated inboxes, reply handling, routing, attachments, webhooks and message logs.
AI agents can connect to Mission Inbox through REST API, SMTP, IMAP, SDKs or MCP. This allows agents to send messages, read incoming email, reply to threads, process attachments and react to email events.
Yes. You can create separate inboxes for each agent, customer, workflow or use case. This keeps identities, conversations, permissions and email activity isolated.

Mission Inbox can support sales agents, customer support agents, browser agents, operations agents, document-processing agents and marketplace agents that need to communicate or complete workflows through email.
