Does Stanford reply to optional updates?

My daughter wrote to her admission officer plus posted an optional update to Stanford by the March 1, 2017 deadline. The optional update form got an auto- response but the e-mailed letter to the admission officer got no response (also sent by fax). Is that your experience too?

I haven’t emailed updates to Stanford specifically, but it is likely that admissions officers are simply swamped right now, with decisions coming out March 31.
