Validate Email Addresses with APILayer API

This n8n workflow validates email addresses using the APILayer Email Verification API, ideal for lead generation, user registration, and newsletter sign-ups to reduce bounce rates and enhance data accuracy.

It starts with a Manual Trigger for on-demand testing, followed by a Set node to input the email and API access key. An HTTP Request node then calls the APILayer endpoint (https://apilayer.net/api/check) with dynamic parameters, returning detailed validity results like format checks, deliverability, and disposable email detection.

Customization options include replacing the manual trigger with webhooks or schedules, adding conditional logic for invalid emails, or integrating with databases/Slack for alerts. Benefits include cleaner mailing lists, higher engagement rates, and cost savings on email campaigns.

Use cases span sign-up forms, CRM data hygiene, and e-commerce checkouts, making it valuable for businesses prioritizing reliable customer communications.
