<p>Do you use regular mail or other ways?</p>
<p>What do you mean? When sending materials to Yale admissions? Then yes, regular postal services are fine.</p>
<p>I am just afraid that the materials may be lost. Should I use priority mail?</p>
<p>The main part of your application is sent online. Supplemental materials, even if lost, will generate a call from Yale to you or your school and you resend. </p>
<p>Normal USPS mail is fine. Just put your return address on the envelope.</p>
<p>Or, do your part in stemming the USPS deficit. Go with Registered Mail or First Class with Confirmation tracking.</p>
<p>I wouldn’t however.</p>
