About Inbox Zero
Inbox Zero is an AI email assistant that organizes a user's inbox and calendar, drafts replies, and helps reduce email backlogs. It sorts incoming email into categories, including Newsletter, To Reply, Marketing, Calendar, Notification, Cold Email, Team, and Urgent, and users can create their own categories. It can draft replies based on email history and calendar availability, bulk unsubscribe from newsletters the user does not read, block cold emails, and show email analytics such as who sends the most email. Users can access email from Slack, Telegram, mobile apps, or the web.
Setup involves connecting a Gmail or Outlook account. The homepage says the service has SOC 2 Type 2 certification and that user data is not used for AI training, but these are the company's own statements and the service may use external services such as calendar and CRM connections. The homepage describes the code as open source and says it can be self-hosted, but the directory record lists the project as not open source, so this should be checked before relying on self-hosting. Teams integration is listed as coming soon. Pricing is not confirmed in this entry.
