Georgetown Graduate financial aid letters

Does anyone know if the financial aid letters for Georgetown’s Masters of Public Policy Program come via email or snail mail and when they get sent out? I got told that I received some merit-based financial aid but I won’t know how much until I get my letter. I need to know where to look out for it. Thanks!

I am told everything from Georgetown arrives via USPS

really? because I have only gotten my acceptances and any other correspondence via email and the Georgetown application portal.
