What is Inbox Zero?
Inbox Zero is an AI email assistant and email client for people managing Gmail or Outlook accounts. The assistant works in the background to organize messages and prepare replies in the user's tone and style. The assistant and email client can each be used independently.
Its tools include plain-language email rules, reply tracking, bulk unsubscribing and archiving, cold email blocking, and email activity analytics. It also provides meeting briefings using email and calendar context, saves attachments to Google Drive or OneDrive, and lets users interact with the assistant through Slack or Telegram. The email client includes a split inbox, multiple accounts, and team comments.
Inbox Zero offers hosted access and self-hosting. The web and Electron desktop clients are open source, while the native iOS app is not described as open source and can connect to a self-hosted server. The repository also references an older Android app. Self-hosting requires infrastructure setup and configuration for production use.
Key capabilities
- Email organization Apply plain-language rules to organize incoming messages and prepare replies in the user's style.
- Reply tracking Track messages that need a reply and conversations awaiting a response.
- Inbox cleanup Unsubscribe from unwanted mail, archive messages in bulk, and block cold emails.
- Meeting preparation Generate briefings using context from email and calendar entries.
- Attachment filing Automatically save email attachments to Google Drive or OneDrive.
- Email client Manage multiple accounts with a split inbox and team comments, independently of the assistant.
Where Inbox Zero fits
Inbox Zero fits into daily email workflows where users need help sorting incoming messages, preparing replies, monitoring unanswered conversations, or clearing accumulated mail. Its meeting briefings and attachment filing extend that workflow into calendar preparation and document storage.
Before deployment, teams should verify Gmail or Outlook account requirements, access permissions, AI configuration, and the behavior of automated rules. Self-hosted deployments also require review of infrastructure and OAuth configuration. Mobile availability should be checked separately, since the source distinguishes the native iOS app from an older Android app.
