Letter or email acceptance first?

Should we be watching our mail or our email for the first notification? TIA

I would say check your portal. I, unlike some people, never got an email saying my portal was updated, but they do post acceptances Fridays at 8:00, so I checked my portal and saw the confetti, and then I think around 5 days later I got the big packet with my letter and some general info. Good luck!
