InboxAPI provides your AI agent with its own personal email address, enabling seamless communication through email. This innovative service allows agents to send, receive, search, reply, and forward emails directly from Claude, Gemini, Codex, or any MCP-compatible client. With InboxAPI, there's no need for server management or SMTP configuration, making it a hassle-free solution for integrating email capabilities into AI workflows.

Key Features

• Instant Setup: Your agent receives a personal @inboxapi.ai email address in seconds without DNS configuration or domain verification.

• Full Email Functionality: Unlike other services that only allow sending, InboxAPI provides a complete email experience, including receiving mail, searching by sender or subject, and following conversation threads.

• Built-In Abuse Prevention: Features like proof-of-work on signup, recipient caps, send quotas, and rate limiting ensure a secure platform.

• Own Infrastructure: InboxAPI operates its entire email stack, not relying on third-party services like Amazon SES or SendGrid.

• Free Forever: The core service is completely free, with no credit card required and no usage tiers, although paid plans with additional features are planned.

InboxAPI is designed to provide AI agents with a reliable and secure email identity, enhancing their ability to interact with the digital world through a universally accepted communication medium.
