🚀 Automated Lead Management: Google Sheets → Instantly + n8n Data Tables

📋 Overview

This workflow automates lead management by syncing data from Google Sheets to Instantly email campaigns while maintaining tracking through n8n Data Tables. It processes leads in batches to avoid rate limits and ensures no duplicates are sent.

⚙️ Complete Setup Guide

1️⃣ Create Your Google Sheet

Option A: Use Our Template (Recommended)

1. Copy this template with test data: Google Sheets Template
2. Click File → Make a copy to create your own version
3. Populate with your lead data

Option B: Create Your Own
Create a Google Sheet with these required columns :

• Firstname - Contact's first name
• Email - Contact's email address
• Website - Company website URL
• Company - Company name
• Title - Job title/position

💡 Pro Tip: Add as many leads as you want - the workflow handles batching automatically!

2️⃣ Set Up n8n Data Table

The workflow uses one Data Table to track leads and their sync status.

Create the "Leads" Data Table:

1. In your n8n workflow editor, add a Data Table node
2. Click "Create New Data Table"
3. Name it: Leads
4. Add the following columns:

Column Name	Type	Purpose
Firstname	string	Contact's first name
Lastname	string	Contact's last name
email	string	Contact's email (unique identifier)
website	string	Company website
company	string	Company name
title	string	Job title
campaign	string	Sync status (e.g., "start", "added to instantly")
focusarea	string	Enriched data from Title field

1. Click Save

📌 Important: The campaign field is crucial - it tracks which leads have been synced to prevent duplicates!

3️⃣ Connect Your Google Sheets Account

1. In the "Get row(s) in sheet" node, click "Create New Credential"
2. Select Google Sheets OAuth2 API
3. Follow the OAuth flow:
   • Sign in with your Google account
   • Grant n8n permission to access your sheets
4. Select your spreadsheet from the dropdown
5. Choose the correct sheet name (e.g., "instantly leads")
6. Test the connection to verify it works

---

4️⃣ Connect Your Instantly Account

1. Go to Instantly.ai and log in
2. Navigate to Settings → API
3. Copy your API Key
4. Back in n8n, open the "Create a lead" node
5. Click "Create New Credential"
6. Select Instantly API
7. Paste your API key
8. Important: Update the campaign ID:
   • Current ID: 100fa5a2-3ed0-4f12-967c-b2cc4a07c3e8 (example)
   • Replace with your actual campaign ID from Instantly
   • Find this in Instantly under Campaigns → Your Campaign → Settings

---

5️⃣ Configure the Data Table Nodes

You'll need to update three Data Table nodes to point to your newly created "Leads" table:

Node 1: "Get row(s)"

• Operation: Get
• Data Table: Select Leads
• Filter: campaign = "start"
• This fetches only new, unsynced leads

Node 2: "Update row(s)1" (Top Flow)

• Operation: Update
• Data Table: Select Leads
• Filter: Match by email field
• Update: Set focusarea to Title value
• This enriches lead data

Node 3: "Update row(s)" (Bottom Flow)

• Operation: Update
• Data Table: Select Leads
• Filter: Match by Email field
• Update: Set campaign = "added to instantly"
• This prevents duplicate sends

---

6️⃣ Configure the Schedule (Optional)

The workflow includes a Schedule Trigger for automation:

Default: Runs every hour

To customize:

1. Click the "Schedule Trigger" node
2. Choose your interval:
   • Every 30 minutes
   • Every 2 hours
   • Daily at specific time
   • Custom cron expression

💡 For testing: Use the "When clicking 'Execute workflow'" manual trigger instead!

🔄 How It Works

Flow 1: Data Transfer (Top Path)

This flow moves leads from Google Sheets → n8n Data Table

Manual Trigger → Get Google Sheets → Batch Split (30) → Update Data Table → Loop

Step-by-step:

1. Manual Trigger - Click to start the workflow manually
2. Get row(s) in sheet - Fetches ALL leads from your Google Sheet
3. Loop Over Items - Splits into batches of 30 leads
4. Update row(s)1 - For each lead:
   • Searches Data Table by email
   • Updates or creates the lead record
   • Stores Title → focusarea for enrichment
5. Loop continues - Processes next batch until all leads transferred

⚙️ Why 30 at a time?

• Prevents API timeouts
• Respects rate limits
• Allows monitoring of progress
• Can be adjusted in the node settings

---

Flow 2: Instantly Sync (Bottom Path)

This flow syncs qualified leads from Data Table → Instantly

Schedule Trigger → Get Data Table (filtered) → Individual Loop → Create in Instantly → Update Status

Step-by-step:

1. Schedule Trigger - Runs automatically (every hour by default)
2. Get row(s) - Queries Data Table for leads where campaign = "start"
   • Only fetches NEW, unsynced leads
   • Ignores leads already processed
3. Loop Over Items1 - Processes ONE lead at a time
4. Create a lead - Sends lead to Instantly:
   • Campaign: "Launchday 1"
   • Maps: Email, Firstname, Company, Website
   • Adds to email sequence
5. Update row(s) - Updates Data Table:
   • Sets campaign = "added to instantly"
   • Prevents duplicate sends on next run
6. Loop continues - Next lead until all processed

🔍 Why one at a time?

• Instantly API works best with individual requests
• Ensures accurate status tracking
• Prevents partial failures
• Better error handling per lead

✅ Key Features Explained

Batch Processing

• Processes 30 Google Sheet leads at once
• Configurable in Loop Over Items node
• Prevents timeouts on large datasets

Duplicate Prevention

• Uses campaign field as status tracker
• Only syncs leads where campaign = "start"
• Updates to "added to instantly" after sync
• Re-running workflow won't create duplicates

Data Enrichment

• Stores job title in focusarea field
• Can be used for personalization later
• Extensible for additional enrichment

Two-Trigger System

• Manual Trigger : For testing and one-time runs
• Schedule Trigger : For automated hourly syncs
• Both triggers use the same logic

Error Tolerance

• Individual lead processing prevents cascade failures
• One failed lead won't stop the entire batch
• Easy to identify and fix problematic records

🧪 Testing Your Workflow

Step 1: Test Data Transfer (Flow 1)

1. Add 5 test leads to your Google Sheet
2. Click the Manual Trigger node
3. Click "Execute Node"
4. Check your Leads Data Table - should see 5 new rows
5. Verify focusarea field has data from Title column

Step 2: Test Instantly Sync (Flow 2)

1. In Data Table, ensure at least one lead has campaign = "start"
2. Click the Schedule Trigger node
3. Click "Execute Node" (bypasses schedule for testing)
4. Check Instantly dashboard - should see new lead(s)
5. Check Data Table - campaign should update to "added to instantly"

Step 3: Test Duplicate Prevention

1. Re-run the Schedule Trigger
2. No new leads should be created in Instantly
3. Data Table shows no changes (already marked as synced)

🚨 Troubleshooting

Issue: Google Sheets not fetching data

• ✅ Check OAuth credentials are valid
• ✅ Verify spreadsheet ID in node settings
• ✅ Ensure sheet name matches exactly
• ✅ Check Google Sheet has data

Issue: Data Table not updating

• ✅ Verify Data Table exists and is named "Leads"
• ✅ Check column names match exactly (case-sensitive)
• ✅ Ensure email field is populated (used for matching)

Issue: Instantly not receiving leads

• ✅ Verify Instantly API key is correct
• ✅ Update campaign ID to your actual campaign
• ✅ Check campaign = "start" in Data Table
• ✅ Verify email format is valid

Issue: Workflow runs but nothing happens

• ✅ Check if Data Table has leads with campaign = "start"
• ✅ Verify loop nodes aren't stuck (check execution logs)
• ✅ Ensure batch size isn't set to 0

💡 Pro Tips & Best Practices

For Beginners:

1. Start small - Test with 5-10 leads first
2. Use manual trigger - Don't enable schedule until tested
3. Check each node - Execute nodes individually to debug
4. Monitor Data Table - Use it as your source of truth
5. Keep backups - Export Data Table regularly

For Optimization:

1. Adjust batch size - Increase to 50-100 for large datasets
2. Add delays - Insert "Wait" nodes if hitting rate limits
3. Filter in Google Sheets - Only fetch new rows (use formulas)
4. Archive old leads - Move synced leads to separate table
5. Add error notifications - Connect Slack/email for failures

For Scaling:

1. Use multiple campaigns - Add campaign selection logic
2. Implement retry logic - Add "IF" nodes to retry failed syncs
3. Add data validation - Check email format before syncing
4. Log everything - Add "Set" nodes to track execution details
5. Monitor API usage - Track Instantly API quota
