Appeal notification?

Hello guys, so last Saturday I went to UW to submit my appeal but found out Schmitz Hall is closed on Saturdays (I know, I should’ve checked) so I went down the road and had the post office mail it and they said it would arrive today (Monday). I was wondering how long the admissions office takes to let you know they received your appeal, and do they do it through email or the portal? Thank you!

They typically send you an email once they receive it, and after receipt of the email it takes 1 - 4 weeks to receive a decision which arrives in the postal mail. I called admissions a few times to clarify this.
