 "summary": "Open-source AI email assistant for Gmail and Outlook that labels incoming mail, drafts replies in your voice, blocks cold email and bulk-unsubscribes; can also be self-hosted.",
 "best_for": "busy founders, executives and small teams on Gmail or Outlook who want their inbox sorted, replies drafted and newsletters cleared by AI, and who like that the code is open source and can be self-hosted",
 "skip_if": "you are not allowed to send email content to third-party AI providers and cannot self-host, you use an email provider other than Google or Microsoft, or you want one flat price for many mailboxes",
 "honest_knock": "There is no free plan: the trial needs a card and converts unless you cancel, though the site leads with 'Get started free'. Pricing is per user, and a second mailbox needs Plus. The terms of service date from July 2023, are short, name no company and say nothing about refunds; the refund promise lives only in the pricing FAQ, within 14 days of upgrading and at the vendor's judgement of value. The service reads your whole mailbox and passes email content to third-party AI providers. Security and popularity claims (SOC 2 Type 2, GitHub stars) are the vendor's own. We have not used Inbox Zero ourselves.",

  "notes": "(read 2026-10-15 in a live browser on getinboxzero.com/pricing with its comparison table and FAQ, the home page, the terms of service dated 16 July 2023 and the privacy policy) Three plans priced per user, plus Enterprise. Starter is $18 per user a month billed annually or $20 monthly: labelling and sorting every email, drafted replies in your voice, a cold-email blocker, bulk unsubscribe and archive, email analytics, pre-meeting briefings and a limited knowledge base. Plus is $28 annually or $35 monthly: two email accounts per user, an AI meeting notetaker, Slack and app integrations such as Notion and Stripe, email digests, auto-filing of attachments and an unlimited knowledge base. Professional is $42 annually or $50 monthly: team-wide analytics, priority support and a dedicated onboarding manager. Enterprise, with SSO, SCIM and on-premise deployment, is priced by sales. Every plan has a 7-day free trial; the home page FAQ says a credit card is required and you are charged when the trial ends unless you cancel. Plan changes are prorated, cancellation keeps the plan to the end of the billing period, and the FAQ offers a refund if you email within 14 days of upgrading and feel you did not get value. Students, nonprofits and open-source projects can ask for a discount by email. It works with Gmail, Google Workspace and Microsoft Outlook.",

Inbox Zero, read on 15 October 2026, is $20 a month or $18 billed annually per user, and adds AI-drafted replies, meeting briefings and a cold-email blocker. SaneBox is the cheaper, quieter filter; Inbox Zero is the AI assistant that also writes."
