Verify email addresses with a code before granting form access

Sends visitors a code by email and only lets them into your form once they confirm it's really them.

How the work actually flows

It repeats. Repeats wrong code re-entered.

Pattern: Structured Loop (21)

The problem it solves

You want the people filling out your forms to have a real, working email address, but checking each submission by hand for fake or mistyped emails wastes time and lets bad data into your list.

Who it fits

Businesses collecting sign-ups or leads through online forms who need clean, verified contact lists.

How it works

  1. A visitor submits their email through your form
  2. A unique verification code is generated and saved
  3. A verification email with the code is sent to them
  4. The visitor enters the code to confirm their email
  5. Once verified, they're let through to your main form
What you get

Verified sign-ups instead of fake ones

You get a form that only lets through visitors who've confirmed their email is real.

What you get

A list of confirmed, verified email addresses with no fake or mistyped entries.

What you need

A Google Sheets account and an SMTP email sending account.

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.
