AI Email Agent — Smart Inbox Automation with Outlook, AI Drafting & Attachment Processing

Turn any Outlook inbox into an AI-powered email response system. This 54-node n8n workflow reads incoming emails, classifies them with AI, processes attachments (images, PDFs, spreadsheets, Word docs), and auto-drafts intelligent replies — you just review and hit Send.

What it does:

• Fetches unread emails from Outlook on a schedule

• Filters out automated/no-reply emails automatically

• Classifies each email as "Needs Reply" or "FYI" using AI

• Downloads and processes attachments — images analyzed with GPT Vision, PDFs parsed, spreadsheets extracted, DOCX converted

• Builds full conversation thread context for the AI

• Drafts accurate, professional replies using a custom AI agent with two tools: a Calculation Engine (customizable pricing/logic in JavaScript) and a Knowledge Base (Google Doc you control)

• Creates draft replies directly in Outlook — never auto-sends

• Logs every draft to Google Sheets for quality tracking

• Tags processed emails in Outlook (Automated / FYI / Draft Created)

• Telegram alerts for errors and rate limits

• Rate limit handling with retry backoff

Customizable for any industry — manufacturing, wholesale, construction, professional services, real estate, e-commerce. Replace the AI prompt, pricing logic, and knowledge base to fit any business.

Production-tested — currently running 24/7 for a real B2B company processing customer emails daily.
