<p>Hi,</p>
<p>I wrote several emails to an admissions officer, asking a couple of questions about the application. After I received a reply, I wrote back a 'thank you' email just to be polite. However, I wonder if it's unnecessary to send a 'thank you' each time the admissions officer replies my question. Would it make a good impression?</p>
<p>(It might seem like an unimportant detail but writing an email to an adcom has always been stressful for me.)</p>
