Automatically sync website email contacts to Google Sheets or a database

This automation template allows users to extract email addresses in bulk from website HTML content.

It is triggered by a webhook request with the target website URL, fetches the HTML, identifies all email addresses using a regex, removes duplicates, and returns the clean list of emails in the webhook response. This capability is valuable for marketing, sales, and outreach efforts that require access to large contact databases. The workflow is built using the n8n automation platform and integrates with the target website as the primary external data source.

The automation workflow is triggered by a webhook request that includes the target website URL as a parameter.

2
Action

Fetch Website HTML

The workflow fetches the HTML content of the target website using the provided URL.

3
Logic

Extract Email Addresses

A regular expression is used to identify and extract all email addresses present in the website HTML content.

4
Action

Filter Out Empty Emails

Any extracted email addresses that are empty or invalid are removed from the list.

5
Action

Remove Duplicate Emails

The filtered list of email addresses is further processed to remove any duplicate entries, ensuring a clean, unique set of contacts.

The final, de-duplicated list of email addresses is returned as the response to the initial webhook request.

Setup guide

1

Add Website Integration Credential

In the Latenode Credentials panel, add a new credential for the website you want to scrape emails from. Provide the necessary API key, access token, or other authentication details required by the website.

2

Configure Webhook Trigger Node

In the Latenode visual builder, add a Webhook node as the trigger for the workflow. Set the Webhook URL and method to receive the initial request with the target website URL.

3

Configure HTTP Request Node

Add an HTTP Request node after the Webhook node. In the node settings, map the website URL from the webhook input to the URL field. This will fetch the HTML content from the provided website.

4

Extract Emails Using Regex

Add a Set node after the HTTP Request node. In the node settings, use a regular expression to extract all email addresses from the website HTML content.

5

Respond with Unique Email List

Finally, add a Respond to Webhook node. This will return the de-duplicated list of email addresses extracted from the website as the webhook response.

Requirements

Obtain a Webhook URL to trigger the workflow when a new website URL is available
Set up a Google Sheets account and create a spreadsheet to store the extracted email addresses
Obtain API access credentials (e.g., API key, OAuth credentials) for the Google Sheets integration
Ensure the Google Sheets integration has write permissions to the designated spreadsheet
