Etiquette for sending another email after the first one went unreplied I applied for study abroad program and so far, now it has been a week after the expected decision date. Whether I get admitted or not also affects my class schedule for Fall semester which will start in the coming week, so I need to get the decision by this Friday. I sent an email to study abroad office, which is the only contact information available, on Monday to ask for an update but did not get any reply. So, my question is: If I choose to send another email, how to make it sound not rude (since my first email was sent just two days ago)?
The important question is the interval between the time you applied and the time you expect an answer.  

If you applied on the day before the decision were announced it is quite possible there was not time to assess your file and sending another email will not help.

If on the other hand your documents were received months ago then another email or better yet a phone call if possible is not inappropriate.

Be mindful that applicants are often optimistic to expect academic decisions to be made within a few days of reception of documents.  Admissions officers may have to deal with 100s of files each containing multiple documents to be scanned so the information can be properly stored and distributed to appropriate faculty for later evaluation, and every link in the chain takes time.
