Send customers to page where they signed up on after welcome popup

Hi @spanier8654, welcome to the community,

It’s definitely possible, but not without a bit of development effort.  In other words, you can take action after a user submits a sign up form, but you would have to write the custom code to “add the product” or any other actions you would want to do to make that happen. 

This is using the Klaviyo’s Javascript event listener for Signup Forms so that as soon as someone submits a Form, you can write code to handle that event to call other functions (like add the Product to their Profile or fire a Custom Event.).   Here’s the technical documentation:

I answered a very similar question on this here that might be helpful too:

Hope that helps!
