Inbox Zero

Inbox Zero is an AI email assistant that organizes an inbox, drafts replies and clears out unwanted mail. It connects to Gmail, Google Workspace or Microsoft Outlook and automatically labels every message with categories such as To Reply, Newsletter, Marketing, Calendar, Notification, Cold Email and Urgent, or custom ones. For emails that need a response, it prepares a draft in the user's voice using email history and calendar availability, and can draw on a calendar or CRM for context. Other features include bulk unsubscribe and archive for mail that is never read, cold email blocking, email analytics showing who writes most and what fills the inbox, pre meeting briefings, and rules written in plain English. Users can work with their inbox from Slack, Telegram, iOS, Android or the web. It suits founders, executives and busy professionals, with team features for higher volume businesses. The code is open source and can be self hosted, the hosted product is SOC 2 Type 2 certified, and the vendor says customer data is not used for AI training. All plans carry a 7 day free trial. Starter is $18 per user per month billed annually or $20 monthly. Plus is $28 annually or $35 monthly and adds an AI meeting notetaker, Slack and app integrations, and an unlimited knowledge base. Professional is $42 annually or $50 monthly and adds team analytics and priority support. Enterprise is quoted through sales.
