The problem it solves

You know a chunk of the emails in your list are dead, fake, or spam traps, but checking each one by hand would take forever. Sending to a dirty list risks your sender reputation and gets your real emails flagged as spam.

Who it fits

A marketing or sales team maintaining a large email list for cold outreach or campaigns.

How it works

  1. You start the check whenever your list needs cleaning
  2. The automation pulls every email address from your Google Sheet
  3. Each address is checked in small batches against a verification service for spam traps, disposable addresses, and mailbox validity
  4. Your spreadsheet is updated row by row with a valid or invalid status
What you get

Addresses you know are safe to email

Every address on your list gets checked for validity, so you know your spreadsheet only holds addresses that are safe to mail.

What you get

A cleaned Google Sheet with every email address marked valid or invalid.

What you need

A Google account and an account with 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.
