Verify lead email addresses in Google Sheets automatically

The automation checks every new lead's email address for validity and updates your spreadsheet with the result.

How the work actually flows

A straight line. Runs once per each unchecked lead row.

Pattern: Multiple Instances without Synchronization (12)

The problem it solves

You collect leads in a spreadsheet but have no easy way to know which email addresses are real before you reach out. Sending campaigns to bad addresses hurts your sender reputation and wastes outreach effort. Checking each email by hand is slow and easy to forget.

Who it fits

Sales teams or small businesses managing lead lists in Google Sheets who want to avoid emailing invalid addresses.

How it works

  1. The automation reads new leads from your Google Sheets list that haven't been checked yet
  2. Each email address is sent to a verification service to confirm it's real and deliverable
  3. The result is written back into the spreadsheet next to that lead
  4. Your team can filter the sheet to see which leads are safe to contact
What you get

Invalid addresses flagged before you ever hit send

Every new lead's email address gets checked automatically, with the result recorded right in your sheet.

What you get

An updated lead spreadsheet showing which email addresses are valid and safe to contact.

What you need

A Google Sheets account and an Anymail Finder API key.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
