Getting Started with n8n

What is n8n?

n8n is an open-source workflow automation tool that enables you to connect different apps and automate tasks. Think of n8n as your personal assistant that can carry out repetitive tasks, such as extracting email addresses from Gmail, with precision.

Setup Prerequisites

Before diving into automation, ensure you have the following in place:

• A working n8n installation
• A Google account with Gmail access
• Basic understanding of nodes and workflows

If you need help with installing n8n, be sure to refer to some comprehensive guides available.

Creating a Workflow to Extract Email Addresses from Gmail

Step 1: Connecting Gmail to n8n

First, you'll need to connect n8n to your Gmail account. This involves setting up the Gmail node in your n8n instance.

1. Add Gmail Node: Open n8n and create a new workflow. Select 'Add Node' and choose the 'Gmail' node.
2. Authorize Access: Configure your Gmail node by authorizing n8n to access your Gmail account.
3. Fetch Emails: Set up the Gmail node to fetch the emails you want to scan. This could be a specific label like "Invoices" or "Monthly Reports."

Step 2: Extracting Email Addresses

Now that you have access to your emails, the next step is to extract email addresses.

1. Add Function Node: Insert a 'Function' node to process the email data. This node will allow you to run custom code to extract email addresses.
2. Write JavaScript Code: Use a regular expression to find email addresses in the email content. An example of JavaScript code to extract email addresses is:

const emailText = items[0].json.body;
const emailRegex = /[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+.[a-zA-Z0-9._-]+/g;
const emailAddresses = emailText.match(emailRegex) || [];
return emailAddresses.map(email => ({ json: { email } }));

Step 3: Storing or Using the Data

Once you have extracted the email addresses, decide how to store or utilize this data.

1. Add Data Storage Node: Use a data storage node like Google Sheets or Airtable.
2. Set Up Data Storage: Configure the node to store the extracted email addresses. You can also set up Google Sheets integration with n8n.

Practical Example: Automating Customer Feedback Collection

Imagine you run a small online store and receive a lot of customer feedback via email. By automating the extraction of email addresses, you can create a list to send personalized follow-up messages or surveys, enhancing customer engagement.

1. Label Customer Emails: Use Gmail filters to automatically label emails from customers.
2. Fetch and Extract: Use n8n to automate fetching labeled emails and extracting email addresses.
3. Email List Creation: Automatically compile these addresses into a mailing list using your n8n workflow.

This process not only saves time but also ensures no customer input is missed, thereby boosting your relationship management efforts.

Tips and Tricks

• Target Specific Emails: Write conditional logic to target specific kinds of emails by their subject or body using n8n's advanced capabilities.
• Run Workflows Periodically: Schedule the workflow to run daily or weekly so you maintain an up-to-date email list.
• Manage Auth Tokens: Ensure security by refreshing expired OAuth tokens automatically using n8n's built-in features.
