# Verify Google Sheets lead emails with Apify Email Verifier

> Quick overview Automatically verify email addresses in your Google Sheets lead list before launching campaigns. This workflow identifies unverified contacts, validates them in batches via SMTP handshake, catch-all and disposable checks, and writes detailed verdicts back to your spreadsheet. How it works 1. Reads unverified rows: Fetches leads from Google Sheets where the status column is empty, ensuring scheduled runs only process new contacts. 2. Deduplicates and batches: Cleans whitespace, drops duplicate addresses to avoid duplicate charges, and groups emails into batches of 100. 3. Live verification: Sends batches to the Apify Email Verifier API to perform syntax, MX, disposable, and SMTP catch-all checks without sending any emails. 4. Maps verdicts back: Matches verification responses by email address (handling case-insensitivity and email tags) to maintain sheet integrity even when results return reordered. 5. Updates sheet: Writes the final status, sub-status, quality score, cat
