Everything Included in AI Mailbox Agent

A complete self-hosted AI email automation platform built for support teams, consultants, and small businesses.

Multi-Mailbox Monitoring

Add as many mailboxes as you need. Each mailbox is monitored independently over IMAP or POP3, with its own polling interval, folder, and security settings. Supports Gmail, Outlook, Microsoft 365, and any standard email server.

Multi-Provider AI Reply Generation

Connect OpenAI GPT-4o, Anthropic Claude, Moonshot Kimi K3, OpenRouter, or any custom OpenAI-compatible endpoint. Each mailbox can use a different provider and model. The AI is prompted with your role, tone, instructions, and signature.

Human Approval Queue

Run in Monitor, AI Draft, or Auto-Reply mode. In draft mode, every AI reply lands in a queue for review before it is sent. Approve, edit, regenerate, ignore, or delete replies with a single click.

Rules Engine

Create conditional rules based on sender, recipient, subject, body content, attachments, and more. Actions include ignore, mark as read, queue for AI draft, auto-reply, disable processing, or log for review.

Conversation History

The AI can see previous messages in a thread so replies are context-aware and consistent. Configure how many historical messages to include per mailbox.

Dashboard & Metrics

Track emails received, processed, replies sent, queue size, and errors across all mailboxes. The built-in activity chart visualizes email volume over the last 7 days.

Security & Privacy

Self-hosted means your data stays on your server. API keys and passwords are encrypted at rest with AES-256-GCM. The app includes CSRF protection, secure session cookies, bcrypt password hashing, and safety instructions to prevent prompt injection.
