Automatically verify email addresses in a Google Sheet

New or updated rows in a spreadsheet trigger an automatic check that marks each email as valid or invalid.

How the work actually flows

A straight line.

The problem it solves

You collect email addresses for campaigns but have no easy way to know which ones will actually bounce. Checking each address one by one is slow, and sending to bad addresses hurts your sender reputation.

Who it fits

Marketers and small business owners managing email lists who want to catch bad addresses before a campaign goes out.

How it works

  1. You add or update an email address in a Google Sheet
  2. The system detects the new or changed row
  3. It checks the email address for validity using an email verification service
  4. Duplicate entries are automatically filtered out
  5. The sheet updates in real time with the verification result
What you get

Bad email addresses caught before a send

Every new email address in your sheet gets checked and marked valid or invalid automatically.

What you get

An updated spreadsheet showing which email addresses are valid, invalid, or risky.

What you need

A Google account and an EffiBotics 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.
