Hi @UYJason,
Thanks for pointing that out. Indeed! Things change very quickly around here :)
In that case, in addition to the other options in my reply, you could consider working with a developer to add an identify function to the page (leveraging Klaviyo cookies to autopopulate that field). It would use the same principles as the solution with the checkbox, in that it would rely on a user being previously cookied in order for the autopopulation the work. The `_learnq.identify()` function is something that is available to see if a user if identified to Klaviyo. You could probably set the default value for the `email_field_label from there. We have a section in our help center dedicated to custom signup forms if you’d like to have a look at the different form options. I’d also consider checking out our partners page if you’re looking to partner with someone to assist with custom coding.
I hope that’s helpful!
