Mails Agent: Self-hosted email infrastructure for AI agents

Mails Agent represents a sophisticated approach to email infrastructure for AI agents and automated systems, offering a level of programmability and control rarely seen in traditional email services. Unlike standard email APIs that provide limited functionality, this solution delivers a full-featured email identity with infrastructure-as-code principles, enabling developers to deploy and customize email capabilities with unprecedented granularity.

The technical architecture leverages Cloudflare's ecosystem, utilizing Workers for computation, D1 for storage, Email Routing for inbound handling, and Resend for SMTP delivery. This design ensures high performance, scalability, and most importantly, complete developer control. Features like full-text search, semantic search via vector indexing, automatic code extraction, and webhook notifications transform email from a passive communication medium into a dynamic, programmable data source.

What sets Mails Agent apart is its holistic approach to email management. Developers can not only send and receive emails but also extract structured data, classify messages, manage attachments, and create sophisticated routing and processing pipelines. The system's zero runtime dependencies and self-hosting capabilities make it particularly attractive for security-conscious teams and projects requiring fine-grained email interaction control.
