Agent Mailbox - Professional Email Infrastructure for AI Agents

Agent Mailbox enables your AI agents to handle back-office workflows with professional email communication without the complexity and risk of integrating them into your existing corporate email infrastructure. As organizations deploy AI agents for long-running, end-to-end processes like invoice reconciliation, compliance reporting, or multi-party approvals, email becomes essential. However, plugging AI agents into the same infrastructure used by your employees creates integration overhead, deliverability risks, and potential brand impact if automated communications aren't properly managed.

Key Capabilities:

• Workflow Context & Continuity - Built-in ThreadID tracking maintains complete chronological conversation history, enabling your AI agents to understand context across multi-step email exchanges and determine appropriate next actions in complex workflows
• Isolated Infrastructure for AI Workflows - Deploy dedicated email infrastructure for your AI agents, protecting your corporate domain reputation while enabling automated processes to communicate professionally under branded subdomains
• Enterprise Deliverability & Reliability - Built on infrastructure delivering 99.9% uptime with optimized inbox placement rates, intelligent reputation management, and automatic bounce and complaint handling, ensuring your workflow communications reach their destination consistently
• Purpose-Built for Workflow Processes - Enable AI agents managing multi-step processes to send updates, receive confirmations, and coordinate with stakeholders via email—the communication channel your business partners already use
• Simple HTTP Integration - Straightforward API endpoints allow your AI agents to send emails, receive responses, and track delivery status without navigating complex corporate email gateway policies or authentication requirements
• Compliance Ready - Complete email logging, delivery tracking, and audit trails support regulatory requirements across financial services, healthcare, and professional services sectors

Built for Back-Office AI Automation:

Agent Mailbox is designed for AI agents managing substantive business processes, purchase order to fulfilment to invoicing, regulatory submission workflows, or client onboarding sequences. Built entirely on AWS infrastructure using AWS SES, Lambda, Aurora, API Gateway and SQS, it provides the communication backbone your AI workflow orchestration requires while keeping automated processes separate from day-to-day corporate email operations.
