Many candidates on the waitlist wonder if they should write letters to the Admissions Committee or if they should stay quiet. Essentially they are asking if they should take an active or a passive approach to the waitlist experience. Our advice at Ivy Admissions Group is emphatically to take an active approach by sending in letters to the Admissions Committee; here is why:
1. There is no downside
Even if the Adcom truly doesn't want to hear from you in any capacity, there is no chance that they would penalize you for thoughtful, respectful, and infrequent update letters informing them of important updates and affirming your commitment to staying under further consideration. If such a strategy can only be helpful or neutral, you have an opportunity for upside with no downside and should absolutely take it. People would wait years and spend tens of thousands of dollars to be accepted to a top MBA program -- on the other hand, the investment it takes to write these update letters is quite small.
2. Prevent your application from becoming stale
Your application will be reviewed in comparison to the submissions in subsequent rounds against applicants who will all have three additional months to grow in achievements and qualifications -- becoming, in essence, three months more qualified and impressive than you. The Adcom has already read your application and taken a pass on you, so it's likely that when it comes to filling interview slots (for those waitlisted pre-interview) or spots in the class (for those waitlisted post-interview) they will almost entirely draw from the fresh candidates. You are competing for fewer spots than you think and need to stand out.
3. Stay ahead of the competition
Many of the deferred and waitlisted candidates will be mounting influence campaigns by writing update letters and having mentors contact the admissions deans (many of whom their mentors will know personally). Silence in this environment is a huge comparative disadvantage.
4. This has worked in the past
We've seen empirically that those who use their time on the waitlist to examine, correct, and redeploy their narrative using the techniques we discuss on this website have a far higher acceptance rate than those who refrain from sending in email updates.
5. This strategy is in-line with the words of the letter
Some schools state explicitly or implicitly that no further materials will be added to your file as you wait on the waitlist. Usually Adcoms say this because if they didn't, they would be flooded with low-quality material from desperate candidates, making their job unmanageable. When we work with waitlisted candidates, we always develop personal improvement plans that figure out what you will want to tell the Adcom has improved about your candidacy in a few months time, and then work backwards to find the steps you need to take in your personal and professional lives to make that happen. Even in the unlikely case that the Adcom won't consider important new facts about your application, waitlist letters will still keep your name on the top of the waitlist manager's mind so that when the Admissions Committee turns to her for help in filling the last few interview invites, she will propose your name.
Conclusion: A low cost investment, if you know what to say!
Ultimately, the call is yours. The base-level odds of getting into an MBA program off the waitlist is pretty comparable to the program's acceptance rate overall -- which is to say, pretty low. By putting you on the waitlist, the admissions committee is telling you that you are "good enough" to be admitted, but that there was something off in your narrative that made them hesitate. Writing (high quality) waitlist letters is a relatively small time investment to make that can have big effects on your candidacy. The key is to identify what was wrong with your narrative the first time around, develop content that actually fixes those shortcomings in your storytelling, and improve the facts of your candidacy along the dimensions where the Admissions Committee found were weak. Getting help on these last three dimensions is where admissions consultants can be quite helpful.
