I'm doing a smart capture form on cloud pages to update some interests of my subscribers. I created a new data extension with this fields. I want to send an "Update interest" Email which redirect to the landing page with this form.
I want the form to pre-populate and take the email of the user that clicked, so the contact don't type it again.
I tried this:
On the email:
On the landing page: I create a hidden field: email. And on a text block I used:
%%[ var @email set @email = RequestParameter("email") ]%%
and on the form:
<input name="email" type="hidden" value="%%=v(@email)=%%">
It didn't work.
Do I need to ask some other information? Or use another request parameter?
I read this: https://help.salesforce.com/articleView?id=mc_es_pre_populating_smart_capture_fields_with_salesforce_data.htm&type=5 and I don't get the "Contact_Owner_ID" thing.
Can someone help me?
