How to address the envelope
Copy the address exactly
Address the envelope to Avenida de Europa 1, 28108 Alcobendas, Spain. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
Add the return address
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.
Buy the certified service
Ask at the counter for the certified service with a return receipt: the fee is on top of the postage, the receipt is postmarked, and the article number traces the delivery.
File the receipt with your copy
Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.
