recipient opens the message through a custom tracking pixel. It integrates **Google Sheets**, **Gmail**, **OpenAI**, and **webhooks** to generate, deliver, and monitor engagement with your email sequence.\n\nIt sends personalized emails containing a unique, invisible tracking pixel and then monitors who opens the email by detecting when the pixel is loaded, logging the activity back to a Google Sheets CRM.\n\n### **How it works:**\n\nThis workflow automates personalized lead-nurturing by integrating Google Sheets, Gmail, OpenAI, and a webhook. It retrieves unsent leads from a CRM-style Google Sheet, generates a unique tracking pixel per lead, and uses OpenAI to craft individualized HTML emails embedding the pixel. Gmail then sends the emails and logs the send status, pixel ID, and date in the sheet. When a recipient opens the email, the tracking pixel triggers an n8n webhook that captures the event, matches the pixel ID to the lead, and updates the sheet with an \u201copened\u201d status\u2014creating a live engagement tracker directly within Google Sheets.\n\n\n### **Setup steps:**\n\nCopy the provided Google Sheet template and populate it with lead data. In the n8n workflow, update all Google Sheets node fields to reference your sheet and replace the placeholder `webhook_url` with your actual webhook endpoint URL. Configure credentials for Google Sheets, Gmail, and OpenAI within n8n. Test the workflow by sending sample emails and verifying that tracking pixel activity updates the correct fields in your sheet. Once confirmed, activate the workflow to enable automated lead nurturing and real-time open tracking.\n" }, "typeVersion": 1 }, { "id": "0985436f-d56b-43a1-83b1-d74152b03c83", "name": "Create pixel image", "type": "n8n-nodes-base.convertToFile", "position": [ 256, 32 ], "parameters": { "options": { "mimeType": "image/png" }, "operation": "toBinary", "sourceProperty": "data" }, "typeVersion": 1.1 }, { "id": "f4a9d59d-25ec-428a-bfd3-bea81fe5a181", "name": "Get vars", "type": "n8n-nodes-base.set", "position": [ 480, 160 ], "parameters": { "options": {}, "assignments": { "assignments": [ { "id": "3c40f4c6-de0e-43da-870d-937ba9740ed0", "name": "pixel", "type": "string", "value": "={{ $('Webhook').item.json.query.pixel }}" }, { "id": "25584f1f-d40a-43b6-8e04-bb7ceadcdfe6", "name": "email", "type": "string", "value": "={{ $('Webhook').item.json.query.email }}" } ] } }, "typeVersion": 3.4 }, { "id": "575935b6-4709-4146-93ee-c6bd47215cad", "name": "Update Open email 1", "type": "n8n-nodes-base.googleSheets", "position": [ 720, 160 ], "parameters": { "columns": { "value": { "OPEN EMAIL 1": "yes", "PIXEL EMAIL 1": "={{ $json.pixel }}" }, "schema": [ { "id": "DATE", "type": "string", "display": true, "required": false, "displayName": "DATE", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "FIRST NAME", "type": "string", "display": true, "required": false, "displayName": "FIRST NAME", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "LAST NAME", "type": "string", "display": true, "required": false, "displayName": "LAST NAME", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "EMAIL", "type": "string", "display": true, "required": false, "displayName": "EMAIL", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "EMAIL 1 SEND", "type": "string", "display": true, "required": false, "displayName": "EMAIL 1 SEND", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "PIXEL EMAIL 1", "type": "string", "display": true, "removed": false, "required": false, "displayName": "PIXEL EMAIL 1", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "OPEN EMAIL 1", "type": "string", "display": true, "required": false, "displayName": "OPEN EMAIL 1", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "REPLY TO EMAIL 1", "type": "string", "display": true, "required": false, "displayName": "REPLY TO EMAIL 1", "defaultMatch": false, "canBeUsedToMatch": true }, { "id": "row_number", "type": "number", "display": true, "removed": true, "readOnly": true, "required": false, "displayName": "row_number", "defaultMatch": false, "canBeUsedToMatch": true } ], "mappingMode": "defineBelow", "matchingColumns": [ "PIXEL EMAIL 1" ], "attemptToConvertTypes": false, "convertFieldsToString": false }, "options": {}, "operation": "update", "sheetName": { "__rl": true, "mode": "list", "value": "gid=0", "cachedResultUrl": "https://docs.google.com/spreadsheets/YOUR_AWS_SECRET_KEY_HERE-cxSmM/edit#gid=0", "cachedResultName": "Foglio1" }, "documentId": { "__rl": true, "mode": "list", "value": "1zgmgqTW3IVfI9BqCGyXHvDj1F80Yn8ibuwAjT-cxSmM", "cachedResultUrl": "https://docs.google.com/spreadsheets/YOUR_AWS_SECRET_KEY_HERE-cxSmM/edit?usp=drivesdk", "cachedResultName": "Lead nurturing" } }, "credentials": { "googleSheetsOAuth2Api": { "name": "" } }, "typeVersion": 4.7 }, { "id": "674a755d-2c6f-480b-88bb-54efd4d9d193", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ 160, -704 ], "parameters": { "color": 7, "width": 480, "height": 432, "content": "## STEP 2 - Set webook url\n\nSet webook url from the node trigger sottostante.
