## Introduction
For sales and support teams, tracking response times to customer inquiries is crucial for maintaining high service levels and customer satisfaction. Automating this process minimizes manual effort, avoids human error, and provides real-time insights into support team performance. In this guide, you will learn how to build an automation workflow using n8n to track response times in your support process efficiently. This is specifically valuable for sales departments that rely on timely responses to nurture leads and retain customers.
### Problem Statement
Support teams often struggle with consistently monitoring the elapsed time between customer messages and agent replies, resulting in delayed responses, lost sales opportunities, and reduced customer satisfaction. Manual tracking in spreadsheets or CRM systems can be error-prone and resource-intensive.
### Who Benefits?
– **Sales teams:** Better visibility on support responsiveness, aiding follow-up prioritization.
– **Support managers:** Real-time insights for performance management.
– **Automation engineers:** A reusable, scalable workflow template.
## Tools and Services Integrated
– **n8n:** Open-source workflow automation tool to orchestrate the process.
– **Gmail or Email Service:** To listen to incoming support emails or to send acknowledgments.
– **Google Sheets:** To log and calculate response times.
– **Slack:** Optional for notifications when response times exceed thresholds.
## Workflow Overview
The workflow monitors incoming support requests and agent replies via emails. It extracts timestamps for initial customer requests and subsequent support agent responses, calculates the response time, and logs the data into Google Sheets for tracking and analysis. Optionally, it sends alerts in Slack if the response time exceeds a defined SLA (e.g., 1 hour).
## Step-by-Step Technical Tutorial
### Prerequisites
1. An n8n instance running (locally, self-hosted, or n8n cloud).
2. Google account with access to Google Sheets.
3. Gmail account configured for support emails.
4. Slack workspace (optional).

### Step 1: Setup Google Sheet for Logging
Create a new Google Sheet with columns:
– Ticket ID (or Email Subject)
– Customer Email
– Initial Request Timestamp
– Response Timestamp
– Response Time (minutes)
– Status (e.g., “Pending”, “Responded”, “Overdue”)
Make sure to share this sheet with the service account email if using OAuth credentials.
—
### Step 2: Configure n8n Credentials
1. Add credentials for Gmail in n8n.
2. Add credentials for Google Sheets.
3. Add Slack credentials if using Slack notifications.
—
### Step 3: Email Trigger – Detect Incoming Support Requests
Use the **Gmail Trigger** node configured to:
– Watch for new emails in the support inbox label.
– Filter emails by criteria (e.g., unread, with specific keywords).
This node triggers whenever a new support request email arrives.
**Settings:**
– Resource: Email
– Event: Email Received
– Filters: Label = “Support”
—
### Step 4: Extract Key Information from Request
Add a **Function** node to parse the incoming email data, extracting:
– Ticket ID or unique identifier (subject or message ID)
– Customer email
– Timestamp of the received email
Example JavaScript code snippet in Function node:
“`javascript
return [{
ticketId: $json[“subject”],
customerEmail: $json[“from”].address,
initialRequestTimestamp: new Date($json[“internalDate”]).toISOString(),
}];
“`
—
### Step 5: Append Request to Google Sheet
Use the **Google Sheets** node with ‘Append’ operation:
– Spreadsheet ID: your Google Sheet ID
– Sheet Name: the tab where data is stored
– Map the fields accordingly:
– Ticket ID
– Customer Email
– Initial Request Timestamp
– Status: set as “Pending”
—
### Step 6: Email Trigger – Detect Support Agent Responses
Add a second **Gmail Trigger** node, configured to watch for outgoing emails from the support agent, ideally filtered by the “Sent” label or folder. This trigger watches for replies matching customer inquiries.
—
### Step 7: Match Response to Request
Add a **Lookup** node (Google Sheets – Read) to find the row corresponding to the Ticket ID (probably present in the email thread subject or reference headers). This requires:
– Searching Google Sheet by Ticket ID or subject line.
—
### Step 8: Calculate Response Time
Use a **Function** node to calculate the elapsed time between the initial request timestamp and the response timestamp.
Example JavaScript:
“`javascript
const requestTime = new Date(items[0].json.initialRequestTimestamp);
const responseTime = new Date($json[“internalDate”]);
const diffMs = responseTime – requestTime;
const diffMinutes = Math.floor(diffMs / 60000);
return [{
responseTimestamp: responseTime.toISOString(),
responseTimeMinutes: diffMinutes
}];
“`
—
### Step 9: Update Google Sheet Row
Use the **Google Sheets** node again with ‘Update’ operation:
– Update the corresponding row with
– Response Timestamp
– Response Time (minutes)
– Status to “Responded”
—
### Step 10: Conditional Check for SLA Breach
Add an **IF** node to check if the response time exceeds SLA (e.g., 60 minutes).
Condition: `responseTimeMinutes > 60`
—
### Step 11: Slack Notification (Optional)
If SLA is breached, send a notification to Slack:
– Channel: #support-alerts
– Message: “Response time for Ticket {{Ticket ID}} has exceeded SLA: {{responseTimeMinutes}} minutes.”
This uses the Slack node with ‘Send Message’ operation.

## Common Errors and Tips
– **Email threading and matching:** Support emails may have varied subjects or lack Ticket IDs. Enforce a ticketing convention or parse ‘In-Reply-To’ headers for accurate matching.
– **Timezones:** All timestamps are stored and compared in UTC to avoid timezone-related errors.
– **Google Sheets API limits:** Batch operations can help avoid quota issues for high volume support.
– **Retry logic:** Add error handling with retry nodes if API calls fail temporarily.
– **Label management:** Automate Gmail label assignment for easier filtering.
## How to Adapt or Scale
– Add integration with CRM platforms like HubSpot to sync response times directly.
– Extend alerts to SMS or email.
– Use databases (e.g., Airtable, PostgreSQL) instead of Google Sheets for better scalability.
– Track additional metrics like first contact resolution or average handling time by expanding the workflow.
## Summary
By following this tutorial, sales and support teams can automate tracking of support response times using n8n, Gmail, Google Sheets, and Slack. This workflow promotes accountability, improves customer satisfaction, and provides actionable insights with minimal manual effort.
### Bonus Tip
Implement a dashboard in Google Data Studio or Tableau connecting to your Google Sheets to visualize response time trends and SLA compliance metrics in real time.
