How to Use n8n to Extract Email Addresses from Gmail

Extracting email addresses from Gmail manually can be time-consuming and prone to human error, especially for marketing teams, business owners, and CRM managers who deal with hundreds of daily emails. Fortunately, n8n provides a no-code automation platform that simplifies this process.

In this article, you’ll learn how to use n8n to extract email addresses from Gmail effectively. We’ll walk through real-world use cases, step-by-step workflows, and practical examples. If you’re exploring advanced n8n integrations for marketing automation or HubSpot syncing, this guide will help you get started.

Understanding n8n and Its Role in Email Data Automation

n8n (pronounced “n-eight-n”) is an open-source workflow automation tool that connects multiple apps, much like Zapier or Make, but with far more flexibility. It allows businesses to automate complex tasks such as lead extraction, email parsing, and contact synchronization without writing code.

Why Automate Gmail Data Extraction?

• Reduce manual errors: Automatically collect sender and recipient data from each email.

• Save time: Eliminate hours spent copying emails manually.

• Enhance CRM efficiency: Sync extracted contacts directly into HubSpot or other CRMs.

• Ensure data consistency: Maintain up-to-date, accurate contact lists.

Step-by-Step: How to Use n8n to Extract Email Addresses from Gmail

Let’s go through a complete workflow setup to extract email addresses from Gmail using n8n.

Step 1: Connect Gmail with n8n

1. Log in to your n8n instance.

2. Create a new workflow and search for the Gmail Node.

3. Authorise Gmail via OAuth2 so n8n can access your emails.

4. Select your Gmail account under Credentials.

Pro Tip: Use a dedicated Gmail account for automations to prevent interference with your personal inbox.

Step 2: Define the Trigger Node

You can use two common trigger setups:

• Gmail Trigger Node — activates whenever a new email arrives.

• Cron Node — runs the workflow at set intervals (e.g., every 2 hours).

For continuous automation, use the Gmail Trigger Node to automatically capture incoming emails.

Step 3: Extract Email Data

Add the Set or Function Node to extract specific fields like:

• Sender’s email (from)

• Recipient’s email (to)

• CC or BCC fields (if needed)

Example using a Function Node:

This simple script isolates the sender’s email address from Gmail headers.

Step 4: Filter Unwanted Emails

Use the IF Node to exclude internal or irrelevant emails, such as:

• Automated system notifications

• Internal team messages (@yourcompany.com)

This ensures that your list only includes valid external contacts.

Step 5: Store or Export Extracted Emails

You can export the collected email addresses using multiple n8n nodes, such as:

• Google Sheets Node: Store emails in a spreadsheet.

• HubSpot Node: Send extracted contacts directly to HubSpot CRM.

• Webhook Node: Send data to an API endpoint for further processing.

For instance, using the HubSpot node, you can automatically add each extracted contact to your HubSpot contact database.

Common Mistakes to Avoid When Extracting Emails with n8n

• Ignoring data privacy: Always obtain consent before processing contact data.

• No deduplication: Use the Merge Node or Function Node to remove duplicates.

Why n8n Is Ideal for Email Extraction Automation

Advanced n8n Setup: Extracting Emails Based on Keywords
