I am setting up a form for compliance with CASL. I don't want to continually have the email opt-in field unchecked on the form when someone who has previously expressly opted-in engages with another form.
Can anyone tell me if, on subsequent form visits, for a lead who has an email opt-in field value is true, will Marketo pre-fill the form by placing a check-mark in the opt-in box on the form (if Form Pre-fill is enabled of course).
If that's not the case, I think the best option is to use progressive profiling and place this question first in the progressive profiling list of fields, with a "Number of Blank Fields" is 1. I believe that should work. Please let me know if you don't think it will.
