What is Inbox Zero?

Inbox Zero is an AI‑powered email assistant that integrates with Gmail and Microsoft Outlook to organize inboxes and draft replies in the user’s voice. It automatically labels incoming messages into categories such as newsletters, marketing, calendar, and urgent, and can bulk unsubscribe and archive unwanted subscriptions.

The assistant drafts responses based on the user’s email history and calendar events, allowing quick approvals and sending. It connects to calendars and CRM data to tailor drafts to availability and customer context. Open‑source code lets users self‑host, customize rules in plain English, and maintain data privacy.
