How to address the envelope
Copy it exactly onto the envelope
The front of the envelope carries 3511 Silverside Rd, Ste 105, Wilmington, DE 19810 and nothing else in the address block. Check the 19810 digit by digit before it goes in the post.
Add the return address
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Certified mail, not a courier
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
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
The letter, written out
The request itself is short: Unnsubby is asked to end the account, stop the charges and confirm in writing, with the name and email on the account and, if you have one, an account or customer number where the brackets are.
