Collect waitlist signups with email verification in Google Sheets

Collects waitlist signups through a form, verifies each email with a code, and logs everyone in Google Sheets.

How the work actually flows

It repeats. Repeats invalid code retries entry.

The problem it solves

Building a waitlist by hand means manually checking whether email addresses are real and tracking who's confirmed and who isn't. Fake or mistyped emails clutter your list and waste your outreach later.

Who it fits

A business launching a product or event and collecting a waitlist of interested signups.

How it works

  1. Someone fills out a signup form with their name, email, and company
  2. The system generates a verification code and asks the person to enter it
  3. It checks the code and keeps asking until a valid one is entered
  4. Once verified, it collects any additional details and marks the signup as confirmed
  5. All entries and their verification status are saved to a Google Sheet
What you get

Verified signups you can trust are real

You collect waitlist signups with a verification step built in, so every entry lands in your spreadsheet confirmed and ready.

What you get

A Google Sheet of verified waitlist signups ready to contact.

What you need

A Google Workspace account and an email-sending service such as Gmail.

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.
