<p>Yesterday--being on the waitlist--, I sent my supplementary letter to Princeton to the email they said to send it to....but I haven't received a confirmation? Do they send confirmation of getting my email, or is it normal not to get anything back?</p>
<p>You could send a mail again stating that you are a waitlisted student[mention your full name and student ID] and that you just wanted to confirm that they have recieved your supplementary letter.The staff at the undergrad admissions office is prompt at answering back.Atleast that is what our experience was with both the undergrad office and the fin aid office.Hope that helps.</p>
<p>I do not think they should get annoyed.You have all the right to know and confirm since 1st may is around the corner.Why don’t you call them up today.</p>
