## Clevermail

Clevermail is a browser extension distributed through the Chrome Web Store that layers an AI writing layer on top of Gmail. Instead of starting every message from a blank compose window, you give the assistant a brief instruction and some context about your business or the recipient, and it returns a complete, professionally worded email draft you can review, tweak and send.

The extension is aimed at people who live in their inbox — sales teams, founders, freelancers, recruiters and support staff — and who lose time finding the right phrasing for routine messages. Because the drafts are generated from the context you supply, the aim is output that reads as if you wrote it rather than as generic template text. Multilingual support means you can produce a message in a language other than the one you think in, which is useful for international clients and partners.

Clevermail installs like any other Chrome extension and works inside the Gmail interface, so the typical workflow of reading a thread, replying and sending stays uninterrupted. The free tier covers light everyday use, with paid options for people who write a high volume of email. The extension is published by the team behind clevermail.co, has a small but positive user rating on the Chrome Web Store, and requires permissions to handle personally identifiable information and personal communications, which is expected for an email assistant — check the developer's privacy policy if data handling matters for your organisation.

**Pricing & Plans:** Freemium. A free tier covers everyday email drafting, with paid plans unlocking higher usage limits and advanced features. Check the Chrome Web Store listing or clevermail.co for current plan details and prices.

- **AI email drafting in Gmail:** Give a short instruction plus context about your business or recipient and receive a complete, professionally phrased email draft ready to review and send, without leaving the Gmail compose window.
- **Personalized, on-tone output:** Drafts are generated from the context and inputs you provide, so the result targets your actual situation and relationship rather than producing generic boilerplate copy.
- **Multilingual support:** Compose and generate messages in languages beyond your native one, which helps when corresponding with international clients, partners or colleagues.
- **Send directly from the extension:** Review the generated draft and send it from within the extension flow, keeping the read-reply-send loop inside Gmail instead of switching between apps.
- **Lightweight browser integration:** Installs as a standard Chrome extension with a small footprint, so it adds AI assistance to the Gmail interface you already use without a separate dashboard.

**Strengths:** Generates complete, professional Gmail drafts from a short prompt and context; Works inside Gmail, so there is no separate app or workflow to learn; Multilingual output is useful for international correspondence; Free tier lets you test it on everyday email before paying

**Limitations:** Requires access to personal communications and personal information, which some organisations will not permit; Only useful if you already work in Gmail on Chrome; Small user base and a single developer listing, so long-term support is less proven

## 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
