Set Up: Email Verifier

Automatically checks if thousands of email addresses are valid and deliverable before sending campaigns. Saves money on email marketing costs and protects your sender reputation by removing bad emails from your lists.

What This Automation Does
1

Upload your email list

Add your email addresses to a Google Sheets spreadsheet or trigger the verification through a web form. The system can handle large lists with thousands of emails.

2

Break into manageable batches

Your email list gets divided into smaller groups to ensure reliable processing and prevent overwhelming the verification servers.

3

Distribute verification requests

The system intelligently spreads your verification requests across multiple email servers to ensure fast, reliable results even with large lists.

4

Check each email address

Each email gets verified to confirm it exists and can receive messages. The system checks for typos, inactive accounts, and undeliverable addresses.

5

Wait between batches

Built-in delays between verification batches ensure the process runs smoothly without triggering rate limits or blocks.

6

Save results to your spreadsheet

Verification results get written back to your Google Sheet with clear status indicators showing which emails are valid, invalid, or risky to send to.

Prerequisites

  • Google Sheets account with your email list
  • Email verification service account (like Hunter.io, ZeroBounce, or similar)
  • API credentials from your chosen email verification provider
  • Email list formatted with addresses in a single column
