About Inbox Zero
Inbox Zero is an open-source AI email assistant for Gmail and Outlook that combines automatic organization, drafted replies, and bulk cleanup. After a two-click connection to Google or Microsoft, it sets up smart categories — Newsletter, To Reply, Marketing, Calendar, Notification, Cold Email, Team, Urgent, or your own — and labels every incoming message automatically, so triage stops being a manual sort. The feature customers cite most is pre-drafted replies: every email needing a response arrives with a draft already written in your tone, based on your email history and your calendar, so you are editing rather than composing. It connects to your calendar and CRM so drafts reflect actual availability and customer data, and it produces pre-meeting briefings. Bulk unsubscribe shows which senders you never read and lets you unsubscribe and archive in one click, while incoming PDFs, receipts, and contracts get filed automatically into the right Google Drive or OneDrive folder. Email analytics show who emails you most and what is clogging the inbox. You can also read, draft, and manage mail from Slack, Telegram, or the web without switching apps, with Teams coming. Configuration is in plain English rather than rule builders. On trust: the code is open source with 9k GitHub stars, the company is SOC 2 Type 2 certified, data is not used for AI training, and self-hosting is available for full control. It reports 20,000+ professional users and was #1 on Product Hunt and GitHub Trending.
