Urgent smith waitlist help please

Hello!! I was waitlisted at Smith, it is my top choice. I have sent in two letters of continued interest to the admissions email and was told they have been added to my file. Was this a mistake? I see people emailing their regional representatives directly, or the dean of admissions. Should I have done that? I am so confused and anxious about this now. Also, should I write another email affirming my interest directly to my AO? Did sending it directly to admissions email hinder my chances of getting off the waitlist?
