## Inbox Zero

Inbox Zero is an AI executive assistant layered on top of Gmail and Outlook, built by developer Elie Steinbock (elie2222) and one of the most-starred open-source email projects on GitHub. Once you connect a Google or Microsoft account, it sorts incoming mail into smart categories such as To Reply, Newsletter, Marketing, Calendar, Cold Email and Notification, so you can triage by intent instead of scrolling chronologically. Every message that needs an answer arrives with a pre-written draft based on your past writing and your calendar availability, which you edit and send from the same view.

The tool is unusually broad for an email assistant. It blocks cold outreach before it reaches your inbox, shows you which senders you never open and lets you bulk-unsubscribe and archive them in a few clicks, and produces email analytics about who emails you most and what is clogging your inbox. Because it is open source and self-hostable, developers can inspect the code or run it on their own infrastructure — the company is SOC 2 Type 2 compliant and states your data is never used for AI training.

Inbox Zero also ships a dedicated email app for Gmail and Outlook across web, macOS, Windows and iPhone, is designed to be used from Slack, Telegram or Microsoft Teams, and offers AI meeting notes and pre-meeting briefings on higher tiers. The core app is free; the AI features are billed as a per-user subscription add-on.

**Pricing & Plans:** Freemium with a 7-day free trial on paid tiers. The email app is free; AI plans are billed per user per month (roughly $20 for Starter, $28 for Plus and $40 for Professional on annual billing, with monthly options costing about 20% more). Enterprise pricing with SSO, SCIM and on-premise deployment is available on request.

- **Automatic inbox labelling:** Incoming mail is sorted into categories like To Reply, Newsletter, Cold Email, Calendar and Notification as it arrives, using default rules or categories you define yourself.
- **Pre-drafted replies:** Emails that need a response get a draft written in your tone and referencing your real calendar availability and CRM context, ready to review and send.
- **Cold email blocking and bulk unsubscribe:** Stop cold outreach from ever reaching the inbox, see which newsletters you never read, then unsubscribe and archive them in bulk.
- **Email analytics:** Dashboards reveal who emails you most, which senders dominate your inbox and how your habits change over time so you can act on it.
- **Open source and self-hostable:** The full codebase is public under an open licence, so teams can audit, extend or self-host it, with SOC 2 Type 2 compliance and no AI training on your data.

**Strengths:** Genuinely open source and self-hostable, unlike most AI email assistants; Free core email app plus optional AI add-on keeps entry cost at zero; Combines triage, drafting, unsubscribe, cold-email blocking and analytics in one tool; Works across Slack, Telegram, Teams, web, desktop and mobile

**Limitations:** Best experience requires connecting Google or Microsoft account data; Free tier excludes most AI features, which need a paid per-user plan; Advanced tiers quickly get pricey for large teams

## Superhuman

Superhuman began as a famously fast email client and has expanded into a broader AI productivity suite. Today it spans Superhuman Go, an assistant that lives inside the apps and tabs you already use with inline suggestions and context-aware chat; Superhuman Mail, its email app with auto drafts, split inbox, auto labels, and auto archive; and Superhuman Docs, a collaborative workspace for documents, tables, data, and workflows.

A large part of the platform is built around agents. You can describe a task in chat or use a visual builder to create an agent, then share it with teammates or publish it to a company directory. Pre-built agents cover common knowledge-work jobs such as preparing for meetings by pulling relevant emails, notes, and docs, turning meeting notes into recaps for each owner, checking claims against company data, and humanising AI-generated text. Superhuman also sits inside the wider Superhuman Platform alongside Grammarly and GPTZero.

Superhuman is a paid product aimed at individuals, teams, and enterprises. The suite integrates with Gmail, Google Calendar, and many workplace tools, and the enterprise tier adds administration and security controls. For exact plan tiers, seat pricing, and included features, check the official pricing page, since packaging has changed significantly as the product has grown beyond email.
