Overview

End-to-end deadline reminder automation across Google Sheets and Gmail.

The AI agent reads a central Google Sheet each morning, identifies tasks by deadline, and classifies urgency into today, 3 days, or 7 days. It then automatically sends customized Gmail notifications to the task owners based on urgency. End-to-end, it logs notification status back to the sheet and maintains consistent, timely reminders across teams.

Example

Example workflow

A realistic scenario showing timing and outcome.

Scenario: A project team maintains a sheet with 12 tasks. At 9:00, the AI agent loads the sheet, identifies 3 tasks due today, 5 due within 3 days, and 2 due within 7 days. It sends tailored Gmail reminders to the respective owners with urgency-specific language. The sheet is updated with notification timestamps, and managers receive a concise log of who was notified and when.

FAQ

FAQ

Common questions about setup, behavior, and results.

The agent compares each task deadline against the current date. It classifies the urgency into three windows: today, within three days, and within seven days. The logic is explicit and can be adjusted to include time zones or custom offsets. Notifications are then tailored to reflect the identified urgency level.

Yes. The agent supports message templates that can be adjusted per urgency level and per recipient. You can change subject lines and body content, and optionally localize messages. Changes apply to all future reminders without modifying the core workflow.

The agent runs on a configured trigger and uses the time context of the Google Sheet and sender account. If teams span multiple time zones, you can set a universal reminder time or create separate sheets per region. You’ll still receive consistent, automated notifications based on the defined windows.

All notifications are logged back to the Google Sheet, including timestamps and delivery status. The audit trail lets you review when reminders were sent and whether recipients acknowledged them. This supports accountability and trend analysis over time.

Overdue tasks can be detected and handled with a separate warning path. You can add an overdue window that triggers additional reminders or escalations. The system is designed to be extended to cover overdue scenarios without altering current flows.

You need an active n8n instance, Google Sheets access, and a Gmail OAuth connection. Prepare a sheet with columns for task name, deadline, assignee, and email. Import the agent configuration, authenticate the Google and Gmail connections, and adjust columns and timing to fit your internal rules.

Security depends on the configured access to Google Sheets and Gmail. Use least-privilege permissions, restrict sheet access, and enable OAuth scopes that are strictly necessary. The agent itself does not store data beyond the configured sheet and logs, and you can implement additional monitoring and encryption as needed.
