Validate Email Addresses with APILayer API

📧 Email Validation Workflow Using APILayer API

This n8n workflow enables users to validate email addresses in real time using the APILayer Email Verification API . It's particularly useful for preventing invalid email submissions during lead generation, user registration, or newsletter sign-ups, ultimately improving data quality and reducing bounce rates.

⚙️ Step-by-Step Setup Instructions

1. Trigger the Workflow Manually:

   • The workflow starts with the Manual Trigger node, allowing you to test it on demand from the n8n editor.

2. Set Required Fields:

   • The Set Email & Access Key node allows you to enter:
     • email : The target email address to validate.
     • access_key : Your personal API key from apilayer.net .

3. Make the API Call:

   • The HTTP Request node dynamically constructs the URL:

     https://apilayer.net/api/check?access_key= {{ $json.access_key }} &email= {{ $json.email }}
     

   • It sends a GET request to the APILayer endpoint and returns a detailed response about the email's validity.

4. (Optional) : You can add additional nodes to filter, store, or react to the results depending on your needs.

🔧 How to Customize

• Replace the manual trigger with a webhook or schedule trigger to automate validations.
• Dynamically map the email and access_key values ​​from previous nodes or external data sources.
• Add conditional logic to filter out invalid emails , log them into a database, or send alerts via Slack or Email.

💡 Use Case & Benefits

Email validation is crucial in maintaining a clean and functional mailing list. This workflow is especially valuable in:

• Sign-up forms where real-time email checks prevent fake or disposable emails.
• CRM systems to ensure user-entered emails are valid before saving them.
• Marketing pipelines to minimize email bounce rates and increase campaign deliverability.

Using APILayer's trusted validation service, you can verify whether an email exists, check if it's a role-based address (like info@ or support@ ), and identify disposable email services—all with a simple workflow.
