Clean your email list in Google Sheets and get a weekly summary

How the work actually flows

A straight line. Runs once per each contact.

The problem it solves

Your contact list quietly goes stale as people change jobs and inboxes fill up or shut down. You usually don't find out until a campaign bounces hard, and manually checking each address in a spreadsheet isn't something anyone has time for. You just want to know, at a glance, which contacts are still good.

Who it fits

Small teams managing a contact list in a spreadsheet who want it kept clean automatically.

How it works

  1. Every Monday, the automation reads every row in your spreadsheet
  2. It checks each email address in bulk to see if it's valid, deliverable, or risky
  3. The results are written back into your spreadsheet next to each contact
  4. You receive a short summary report by email
What you get

Contacts you know are safe to email

You get a weekly view of which email addresses in your list are safe to send to and which ones need a second look.

What you get

An updated spreadsheet with a verification status for every contact, plus a weekly summary email.

What you need

A Google Workspace account (Sheets and Gmail), an OpenAI API key, and an email verification service.

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.
