<p>My employer e-mailed me my recommendation and I have to send it to colleges myself. Am I supposed to put my home address, my school’s address, or my employer’s company address as the return address?</p>
<p>I’d suggest to use your home address because if the letter is returned for some reason, it will come back to you. If it goes to your HS or employer, it might not be attended to immediately.</p>
<p>Everything on the physical envelope is for routing only; the envelope gets tossed 2 seconds after the contents are retrieved. entomom’s advice is spot on.</p>
