PDS / Hun : How Do They Let You Know?

Prep School Admissions
1

Hi all,
For those with knowledge of Princeton Day and Hun School - how do they let you know if you are accepted? e-mail or snail mail? Does it arrive on March 10 or earlier/ later?
Thanks

Hun sends an email at 12:01 am on March 10. Looks like spam.

Not sure about PDS.

I think PDS sends a letter via snail mail. I don’t know if it is sent on March 10 or should arrive on March 10.
