UCB Waitlist letter tips?

Hey, if anyone who’s been accepted off a college waitlist is reading this, could you provide me with some tips for the waitlist letter that you send when opting in for the waitlist? It would be even better and greatly helpful if you could provide the waitlist letter that got you in. Thank you.

@Rarecreature101 and All CC posters:

Please do not post your waitlist letter on this website or any internet website. If you are interested in helping OP out, them PM your tips but I would also be hesitant in providing a letter to this anonymous poster.
