## What it is
Zero (Mail0) is an open-source, self-hostable email client that unifies multiple providers like Gmail and Outlook into one privacy-first inbox. It integrates AI agents and LLMs to modernize email workflows while keeping data under user control.

## Use cases
- self-host a private gmail alternative
- unify multiple email accounts in one inbox
- manage email with ai agents
- privacy-focused email client without tracking
- connect gmail and outlook in one app
- open source email web app

## When to choose
- you want a transparent, open-source email client you can self-host
- you need a unified inbox across Gmail, Outlook, and other providers
- you want AI-assisted email features without giving up data ownership

## When to avoid
- you need a full email server or hosting - Zero is a client, not an SMTP/IMAP server
- you require a battle-tested, enterprise-grade email solution with long-term support
- you prefer a native desktop or mobile app rather than a web application
