Prevent your Unsubscribe form from creating new leads
Help, new leads are coming in from our Unsubscribe form!
Yep, that happens. When people forward emails to other accounts and click a tracked Marketo link, they may think the pre-filled Email Address is wrong and “correct” it.
The form field is visible and editable by default, so nothing stops them:
Problem is, they haven’t unsubscribed the address you’re actually sending to. Instead, they’ve created a new (and instantly unsubscribed) lead. Then you’ll keep sending to the old address, they’ll keep thinking your form is broken, and so on. Lose-lose.
Solution: set the disabled attribute on the <input>. The JS couldn’t be simpler:
MktoForms2.whenReady(function(readyForm){
const formEl = readyForm.getFormElem()[0],
emailEl = formEl.querySelector("input[name='Email']");
emailEl.disabled = true;
});
That alone will prevent them from editing the field. Styling the input makes its locked-ness more apparent:
.mktoForm i
