your friend is either lying or being tricked. Yale does not email rejection decisions to anyone. Applicants log into their portals and check their decisions on the official notification day. This year, it’s Mar 31. For those who do not log into the system, the university sends an official letter 7 days after notification day. For those who log in and find their rejection status, no letter is ever issued.
MODERATOR’S NOTE:
I would not have closed this thread, but the caps lock was giving me a headache, and I did not feel like editing more than the headline. Regardless, the definitive answer was given - RD decisions have not been released.
