What this skill actually does
What is Inbox Zero?
How the Skill Works
The Inbox Zero skill connects AI agents to email management workflows through its REST API and MCP server. The AI personal assistant component uses natural language rules (similar to Cursor rules) to define how incoming email should be handled: categorizing messages, drafting replies that match the user’s writing style, labeling conversations, and archiving low-priority mail automatically.
The Reply Zero feature tracks emails that need responses and those awaiting replies from others, creating a prioritized action queue. The bulk unsubscriber analyzes email patterns to identify newsletters and marketing emails the user never reads, enabling one-click unsubscribe and archive operations. The cold email blocker uses AI classification to identify and auto-archive unsolicited outreach.
Integration Points
Inbox Zero integrates with Gmail via Google Pub/Sub for real-time email processing and Microsoft Outlook through the Graph API. The MCP server exposes email management tools to any MCP-compatible AI client. Slack and Telegram integrations allow users to manage their inbox through chat interfaces. The platform uses Upstash Redis for caching and supports deployment on Vercel with one-click setup.
What It Outputs
The skill outputs email triage decisions, drafted replies, unsubscribe actions, analytics reports with activity trends, and meeting briefs that pull context from email and calendar data. Smart filing automatically saves email attachments to Google Drive or OneDrive based on configurable rules.
