🧑‍💻 Description

This workflow automatically fetches new Gmail messages since the last run and appends them into a Google Sheet with their ID, snippet, and timestamp.

It’s designed for professionals, small business owners, and operations teams who need a simple way to keep an ongoing log of emails, build lightweight CRMs, or power downstream automations like email tracking, reporting, or follow-up reminders.

⚙️ Setup Instructions for Gmail → Google Sheets Email Log

1️⃣ Connect Gmail

  1. In n8n → Credentials → New → Gmail OAuth2
  2. Log in with your Gmail account & approve access
  3. Attach this credential to the Get new messages node in the workflow

2️⃣ Connect Google Sheets

  1. Copy this Google Sheet template into your own Drive
  2. In n8n → Credentials → New → Google Sheets (OAuth2) → log in with your Google account & save
  3. In the workflow, select your Spreadsheet ID and Worksheet (Sheet1 by default) in the Google Sheets nodes

🧠 How Email Logging Automation Works

  • Get Current Emails → Reads the last logged messages from Google Sheets
  • Get Max Date → Finds the most recent email timestamp
  • Combine → Passes the last timestamp and today’s date together
  • Get New Messages → Fetches all new Gmail messages after the last logged date
  • Add Emails to Sheets → Appends message ID, snippet, and date to the sheet

🎛️ Customization Guidance

  • Filter by Sender or Subject → Modify the Gmail query to only log messages from specific addresses or with certain keywords.
  • Track Labels → Add Gmail labels to your sheet to separate categories (e.g., “Leads,” “Support,” “Invoices”).
  • Auto-Reply → Extend with an additional Gmail node to send automated responses to new messages.
  • Send Alerts → Add a Slack or Email node to ping your team whenever a new email is logged.
  • Analytics → Use Google Sheets formulas or connect to BI tools to analyze trends like response times or sender frequency.
