AI Daily Email Summary - Auto-Delivered to Slack, WhatsApp & Docs (Gmail + Gemini)
AI Daily Email Summary - Auto-Delivered to Slack, WhatsApp & Docs (Gmail + Gemini) Summary Stop starting your day by drowning in unread emails. This workflow runs every morning and turns your Gmail inbox into a clean, prioritized briefing — automatically organized into what needs your attention, what meetings are coming up, and what you can read later. The summary lands wherever you already live: Google Docs, Gmail, Slack, or WhatsApp. Powered by Google Gemini 2.5 Flash, with a built-in privacy layer that scrubs passwords, OTPs, and API keys before they ever leave your n8n instance. Key features Prioritized daily briefing:** Gemini reads your last 24 hours of email and groups it into Action Required, Meetings & Events, and Important Updates — so you know exactly where to focus. Deliver anywhere:** Route your summary to Google Docs (as a daily log), Gmail (as a formatted report), Slack (as a DM), or WhatsApp — toggle each channel on or off from a single config node. Safe to use with AI:** A regex-based privacy layer scrubs sensitive patterns (OTPs, passwords, API keys, card numbers) inside n8n before anything reaches the AI model. Zero wasted API calls:** If your inbox is empty, the workflow skips the AI step entirely and sends a clean "no emails" status instead. Built-in error alerts:** If any step fails — expired credentials, API error — you get a diagnostic email automatically so nothing breaks silently. How it works Trigger: Runs on a daily schedule (fully configurable). Fetch & clean: Pulls primary emails from the last 24 hours and scrubs sensitive patterns before processing. Summarize: Gemini 2.5 Flash generates a formatted text summary, categorized by priority. Deliver: Your summary is routed to whichever channels you've toggled on in the config node. Monitor: A global error handler catches failures and emails you a crash report. Nodes used Gmail (Fetch, Send, Error Alert) Google Gemini (LangChain Native Node) Slack (Post Alert) WhatsApp Business Cloud API Google Docs (Create & Append) Schedule Trigger Error Trigger Code (PII Scrubbing & Formatting) Setup instructions Credentials: Connect Gmail, Google Docs, Slack, WhatsApp, and your Google Gemini API key. (Note: You only need one Gmail OAuth2 credential. n8n will use this single connection for both fetching your inbox and sending the final summary email). Config node & Fallback: Open ⚙️ Set Configuration and fill in your target email, Slack user ID, and WhatsApp number. (Optional: Open the "Gmail: Send Error Alert" node at the bottom and replace PASTE_FALLBACK_EMAIL_HERE with a backup admin email, ensuring you get crash reports even if the config node fails). Toggle channels: Set each receiveOverviewIn... field to true for the platforms you want to activate. Test: Click Test Workflow — a sample email with a dummy password is pinned to the trigger so you can see the PII scrubber and summary in action immediately. Activate: Switch the workflow to Active and your first briefing runs on schedule.
