Automate Task Deadline Reminders with Google Sheets and Gmail (Today/3-Day/7-Day) — n8n Workflow

Medium complexity⏰ Scheduled8 nodes🏷️ Project Managementby Yuki Hirota

Overview

Task Deadline Reminder Workflow (Today / 3-Day / 7-Day) Task deadline management manually is inefficient and leads to missed deadlines—especially when teams rely on spreadsheets and individual reminders.
This workflow automates the entire follow-up process by reading a centralized task sheet in Google Sheets every morning, checking the deadline for each task, and sending automatic email notifications to the responsible person based on urgency.
Tasks due today, within three days, or within on
