About This Workflow
How it Works
This n8n workflow demonstrates a fundamental automation task: extracting the domain name from an email address. It's designed to be simple and clear, perfect for beginners or as a building block for more complex automations.
- Manual Trigger: The workflow starts when you manually click the 'execute' button.
- Set Sample Email: A 'Set' node pre-defines a sample email address (
email@domain2.com). This serves as the input data for the next step. - Extract Domain Name: A 'Function' node contains JavaScript code that takes the sample email, finds the '@' symbol, and extracts the substring after it – the domain name. The extracted domain is then returned for further use.
Key Features
- Visual Workflow Builder: Design and manage automations with an intuitive drag-and-drop interface.
- Pre-defined Sample Data: Easily test and understand the workflow with a hardcoded sample email.
- Custom JavaScript Functions: Leverage the power of JavaScript within n8n to perform specific data manipulations.
- Clear Node Connections: Understand data flow with explicit connections between nodes.
How To Use
- Import the Workflow: Load this JSON into your n8n instance.
- Execute Manually: Click the 'On clicking 'execute'' node's execute button.
- View Results: The 'Extract domain name' node will output the extracted domain (
domain2.com). - Adapt for Your Data: Replace the sample email in the 'Sample email' node with your actual email data source (e.g., from a webhook, database, or file).
Frequently Asked Questions
No, this specific workflow does not require any special credentials or API keys. It uses built-in n8n nodes and standard JavaScript functions to process local data. You only need an active n8n instance.
The current JavaScript function assumes a valid email format. To handle invalid inputs, you could add a conditional check within the 'Extract domain name' function node. For instance, check if the '@' symbol exists before attempting to split the string, and return an error or a default value if it doesn't.
Yes, absolutely. The 'Sample email' node currently sets a single email. To process a list, you would replace the 'Set' node with a node that fetches multiple emails (e.g., a 'Read from CSV' node, a database query node, or an API node). The 'Extract domain name' function node will then be executed for each email in the list.

Super useful for quick data parsing! Been looking for a simple way to strip domains for a contact enrichment project. n8n always delivers.

Just starting with n8n and this example made the 'function' node click for me. The JS code is straightforward. Thanks for sharing!

Nice! This is a foundational piece. I often use this pattern after pulling leads from a CRM to quickly group them by company domain. Efficient.
