AI-Powered Daily Email Summaries to Slack & WhatsApp

Transform your overwhelming email inbox into a clean, prioritized daily briefing that arrives automatically in Slack, WhatsApp, or Google Docs. This AI-powered n8n workflow uses Google Gemini 2.5 Flash to intelligently categorize your last 24 hours of Gmail messages into actionable insights—so you start each day knowing exactly what needs attention.

What this workflow does

Every morning, this automated workflow scans your Gmail inbox and creates a structured summary organized into three key categories: Action Required, Meetings & Events, and Important Updates. The AI-generated briefing is then delivered to your preferred channels—whether that's a Google Docs daily log, formatted Gmail report, Slack direct message, or WhatsApp notification. You can easily toggle each delivery channel on or off through a single configuration node.

Built with privacy in mind, the workflow includes a regex-based scrubbing layer that removes sensitive data like passwords, OTPs, API keys, and card numbers before any content reaches the AI model. Smart efficiency features ensure zero wasted API calls when your inbox is empty, and built-in error alerts notify you immediately if credentials expire or API issues occur.

Use cases

• Busy executives who need prioritized email insights without manual inbox diving
• Remote teams wanting daily email summaries delivered directly to their Slack workspace
• Project managers tracking client communications and meeting requests across multiple channels
• Sales professionals monitoring prospect responses and scheduling updates via WhatsApp
• Consultants maintaining organized client communication logs in Google Docs
