## Introduction
Mail-0 (also called Zero) is an open-source email application that puts privacy and security first. It provides a modern, clean email experience while ensuring users retain full ownership of their data, with optional AI features that respect privacy boundaries.

## What Mail-0 Does
- Provides a full-featured email client with a polished, modern interface
- Connects to standard email providers via IMAP/SMTP protocols
- Offers AI-powered email categorization and smart replies with privacy controls
- Supports multiple email accounts in a unified inbox
- Delivers end-to-end encryption options for sensitive communications

## Architecture Overview
Mail-0 is built with Next.js and TypeScript on the frontend, using a modular architecture that separates the email protocol layer from the UI. The backend handles IMAP/SMTP connections and optional AI processing, while the frontend renders a responsive single-page application. Data flows through a clean API layer, and the AI features operate with explicit user consent.

## Self-Hosting & Configuration
- Clone the repository and configure environment variables in `.env`
- Set up your IMAP/SMTP credentials for each email account
- Optionally configure AI provider keys for smart features
- Deploy with Docker or run directly with Node.js
- Configure TLS certificates for production deployments

## Key Features
- Privacy-first design with no tracking or data collection
- Modern, responsive UI built with React and Tailwind CSS
- AI-powered email organization that runs with user consent
- Open-source codebase with transparent security practices
- Multi-account support with unified inbox view

## Comparison with Similar Tools
- **Thunderbird** — mature desktop client but heavier and less modern UI
- **Roundcube** — web-based but lacks AI features and modern design
- **ProtonMail** — privacy-focused but proprietary and subscription-based
- **Tutanota** — encrypted email but closed-source client
- **K-9 Mail** — Android-only, no web interface

## FAQ
**Q: Does Mail-0 store my emails on its servers?**
A: No. Mail-0 connects directly to your email provider via IMAP/SMTP. Your emails stay on your provider's servers.

**Q: Are the AI features required?**

**Q: Can I use Mail-0 with Gmail, Outlook, or other providers?**
A: Yes. Any email provider that supports standard IMAP/SMTP protocols works with Mail-0.

**Q: Is Mail-0 production-ready?**
A: Mail-0 is under active development. Check the repository's README for the latest stability status before deploying in production.
