How to address the envelope
Use the address letter for letter
Address the envelope to 1515 W 22nd St, Suite 450, Oak Brook, IL 60523. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
Put your own address on it
Your name and postal address go top-left on the front (or the back flap). If the letter cannot be delivered it comes back to you, which is itself evidence of the attempt.
Send it by certified mail
Take the letter to a post office counter and ask for certified mail: you get a postmarked receipt and a delivery record. Keep the tracking number and check it until it shows delivered.
File the receipt with your copy
Hold on to the letter copy, the receipt and the tracking page.
