How to address the envelope
Copy the address exactly
Copy 48 West 38th Street, New York, NY 10018 letter for letter. A wrong digit in 10018 is enough to send the letter on a detour.
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 NumberGuru has moved.
Ask for 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
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: NumberGuru 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.
