How to address the envelope
Copy it exactly onto the envelope

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
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.
Keep the proof together
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
The letter to send
The request itself is short: Dyn is asked to end the account, stop the charges and confirm in writing, with the account email, the domain or server name and the invoice number of the plan being cancelled where the brackets are.
