Looking to update them via email, which email address do I send the updates to? I applied to every UC except Berkeley, Santa Cruz and Merced.
Updates on what in particular?

Personal information. I want to tell them about certain circumstances not mentioned in my application involving my test scores
If they did not send you a supplemental review, any issues cannot be addressed using emails other what is mentioned on theirvwebsite I would have your counselor contact admissions on your behalf and see if the issue can be noted in your file.
Could I just send it to the general admissions email and see if that works?
I would call UC admissions first since it is fairly late in the decision timeline and there is no guarantee that it will be considered in your UC Decision or make it into your file.
