Automate Email Validation in Google Sheets with Email Validator AI

📊 n8n Workflow: Email Validation & Google Sheets Update

This workflow automates the process of validating email addresses stored in a Google Sheet. It reads each email, checks if it's disposable or fake using Email Validator AI via RapidAPI, and updates the same row with the result. All interactions with Google Sheets are done securely using a Google Service Account.
