How to address the envelope
Copy the address exactly
Address the envelope to Rue Léon Patoux 4, 51100 Reims, France. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
Add the return address
Top-left, your own name and address. A return address is what the post office needs to send the letter back if Helium has moved.
Send it certified
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
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.
