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 [Profile (Markdown)](https://openaitools.app/tool/inbox-zero.md) ## Protime Protime sits inside the mailbox rather than in a separate app. It connects to Outlook or Gmail with one permission, reads along, files newsletters and cold outreach into their own folders, and leaves replies waiting as drafts in your own voice. It never sends on your behalf: you read, edit and press send. Alongside that it briefs you each morning on news from your industry and contacts, and proposes calendar entries and tasks from your correspondence. The distinctive part is the commercial-register layer. Switzerland publishes hundreds of official notices every working day, covering bankruptcies, calls for creditors, debt-restructuring moratoriums and management changes. Protime tracks the partner companies it recognises automatically from your mail and surfaces anything relevant the next morning with the official publication attached, deadlines pushed into your calendar, and a clearly internal warning note inserted in the reply draft. Pricing is transparent and Swiss-market focused. The Pro plan costs CHF 39 per person per month (or CHF 390 a year, two months free) with a 14-day trial and no credit card. Teams of three or more move to the annual Team plan from CHF 1,800 a year, which adds Company Watch for up to 500 named companies and the building guardian. It is in daily use at the Swiss retailer Loeb AG in Bern and holds CASA Tier 2 certification. **Pricing & Plans:** Pro plan: CHF 39 per person per month, or CHF 390 a year (two months free), with a 14-day free trial and no credit card required. Team plan: from CHF 1,800 per year for 3 seats (each extra seat CHF 50/month), invoiced annually. A register subscription costs CHF 100 a year, and open lookups on registerbuch.ch are free. Add-ons include an AML package at CHF 39/month and Company Watch from CHF 29/month. - **Commercial-register partner radar:** Every working day, Protime checks the companies in your correspondence against the Swiss commercial register and reports bankruptcies, debt moratoriums, calls to creditors and lost signing authority, with the official publication as proof. - **Draft replies in your voice:** Replies are prepared as drafts inside your mailbox, never sent automatically. It also inserts internal warning notes when a partner company looks troubled or new bank details appear. - **Inbox sorting and VIP rules:** Newsletters, cold outreach and FYI-only mail are filed into their own folders so what stays in the inbox is what actually needs an answer. - **Morning briefings and calendar prep:** A daily digest of news relevant to your industry and contacts, plus proposed meetings pencilled into your calendar and tasks pulled from your email. - **Company Watch and add-ons:** Track up to 500 named companies with a 90-day look-back, and add optional modules such as the AML/PEP report, trademark watch and building guardian. **Strengths:** Connects the commercial register directly into the inbox, a genuinely useful signal for Swiss businesses; Never sends on your behalf — every reply stays a draft you control; Transparent pricing with a 14-day free trial and no credit card; Works in Outlook and Gmail with a one-click setup and folders inside your existing mailbox **Limitations:** Tightly focused on Switzerland, so the register checks only apply to Swiss companies; Requires a paid plan for the register checks; the free tier is only news tokens and search; Some features such as the AML package, trademark watch and Company Watch cost extra [Profile (Markdown)](https://openaitools.app/tool/protime.md) ## Frequently Asked Questions ### How do Inbox Zero and Protime compare in monthly traffic?
