Does Purdue send out acceptance letters?

I just got accepted last Wednesday, and I have been anxiously checking the mail every day for it. My decision letter still hasn’t shown up in my portal, either. Anyway, I was just wondering if they send anything because this is my first acceptance, and I really just want physical proof of it haha

They do, yes. I got accepted a few weeks back and got the letter a week or two later. It includes your letter of acceptance, as well as other materials with info about the university and the different housing options. Mine was available online before it came in the mail, though.
