🚀 Overview

This PR adds the Daily Email Notification workflow to the Gmail_and_Email_Automation category.

It acts as a privacy-focused Executive Email Assistant that runs entirely locally. Instead of just forwarding emails, it batches the last 24 hours of your inbox, filters out the noise (promotions, newsletters), and provides a concise, action-oriented summary via a local LLM (Ollama).

✨ Key Features

• Local-First Privacy: Uses a local Ollama instance for all summaries. No email content ever leaves your infrastructure for processing.
• Intelligent Noise Filtering: Pre-filters obvious marketing and notification noise before summarization.
• Thread Grouping: Deduplicates email threads to provide context without repetition.
• Multi-Channel Delivery: Primary delivery via Telegram bot, with an automatic fallback to ntfy if delivery fails.
• Sanitized Import: Includes workflow.community-template.json, which is stripped of private credential IDs and local metadata for a clean import experience.

🛠 Requirements

• Self-hosted n8n instance (uses the Execute Command node for HTML-to-text processing).
• Local Ollama instance.
• Telegram Bot API Token / ntfy topic (optional).

📁 Changes

• Added Gmail_and_Email_Automation/Daily Email Notification.json
• Updated README.md in the Gmail & Email Automation section.

✅ Checklist

• Valid n8n JSON format.
• No personal credentials or API keys included.
• Tested on local n8n environment.
• Follows the category structure and naming conventions.
