Then acceptance email. Good thing I had a long list of things to achieve before I went public with rwjwction/acceptance. I am happy to be accepted. For all those rejected, I have applied to YC 6 times since 2012 or 2013 I think. All rejects. One business was adapted by government (it wasn't going to be super profitable, but was really key to my government ops plus led to a scholarship at MIT). Two startups floundered but led me to my current startup(pivot after pivot supported by a somewhat sufficient consultancy).
All in all continue executing. That's what important.
