ZapBounce and Unbounce

Unbounce pages almost always sit behind paid traffic. That changes the arithmetic on a mistyped address, because you have already paid for the click that produced it.

At typical B2B cost per click, a lost lead from a typo is worth many times the cost of the verification that would have caught it.

You paid for the click that produced the typo

A visitor arrives through an ad, converts, and mistypes their address. The conversion is recorded, the cost per acquisition looks fine, and the lead is unreachable.

That distorts the reporting as well as losing the lead. Your ad platform counts the conversion, so the campaign appears to be working better than it is.

On a page with a real cost per click, catching the typo before the visitor leaves is the highest-value verification there is.

How the data moves

  1. Verify on field blur through a script manager entry

    Unbounce's script manager holds custom JavaScript. The call goes to your own proxy endpoint, never directly with a key in the page.

  2. Show the suggestion inline

    The visitor is still on the page and about to click submit. This is the moment the correction costs nothing.

  3. Let the submission through regardless

    A blocked conversion on a paid page is a click you paid for and did not capture.

  4. Pass the verdict as a hidden field

    So the CRM receives it with the lead and nobody re-checks later.

Setting it up

  1. Build a small server-side proxy endpoint that holds the key and calls the verify endpoint.
  2. Add a script manager entry that calls the proxy on the email field's blur event.
  3. Show the typo suggestion inline as a clickable correction.
  4. Add a hidden field for the verdict and populate it from the response.
  5. Allow every submission through whatever the verdict says.
  6. Compare the ad platform's conversion count against deliverable leads once a month.

Unbounce: common questions

Can I call the API directly from the page?

No. The key would be in the page source, visible to every visitor including the ones arriving from your ads.

Should a bad verdict block the form?

No. You paid for that click. Show the suggestion and take the lead either way.

What does a lost lead cost here?

Your cost per click divided by your conversion rate. On most B2B landers that is many multiples of a verification credit.
