Domain Extractor: URL & Email Domain Parser

The Domain Extractor workflow is a specialized n8n automation designed to efficiently cleanse URLs and extract their domain names. It supports a vast array of top-level domains (TLDs), including unconventional ones such as 'co.uk', ensuring accurate parsing for diverse URL formats. Additionally, it processes email addresses to pull out the domain and flags if it's from a free email provider like gmail.com, outlook.com, or yahoo.com.

This workflow leverages a comprehensive JavaScript code node with an extensive TLD list sourced from the Public Suffix List on GitHub, making it robust against edge cases in real-world data. Users simply pass a 'url' or 'email' variable via the 'Execute Workflow' node, and it outputs the cleaned domain along with provider detection for emails.

Ideal for data extraction pipelines, lead validation, web scraping cleanups, and CRM integrations, it saves hours of manual parsing or custom scripting. Benefits include high accuracy, scalability for batch processing, and seamless integration into larger n8n workflows for IT, marketing, or development tasks.
