Checks every subscriber's email address, removes the bad ones, and keeps a clean list ready for your next campaign.

How the work actually flows

It branches. Exactly one path is taken; runs once per each subscriber.

The problem it solves

Your subscriber list has been growing for years and nobody has gone back to check which addresses still work. Bad and disposable emails quietly hurt your deliverability and make it harder to trust your open rates.

Who it fits

Marketing teams and anyone managing an email list who wants better deliverability without manual list scrubbing.

How it works

  1. A cleanup request comes in for your subscriber list
  2. Every subscriber's email is checked for validity, spam traps, and disposable domains
  3. Each contact is sorted into keep, remove, or flag for review
  4. Bad addresses are removed straight from the list
  5. The good addresses are saved to a clean, ready-to-use subscriber sheet
What you get

Subscriber lists cleared of bad addresses

You get a clean, ready-to-send subscriber list with invalid and risky email addresses automatically removed.

What you get

A cleaned subscriber list in Google Sheets, with bad addresses removed and a summary of what changed.

What you need

A Google account and an email verification service subscription.

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.
