How to address the envelope
Write the address as printed
The envelope reads 4600 East Washington Street, Suite 300, Phoenix 85034. Match the spacing and the box or street line exactly as printed.
Add your return address
Top-left, your own name and address. A return address is what the post office needs to send the letter back if Namecheap has moved.
Send it by 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.
Keep what the post office gives you
Your copy of the letter, the mailing receipt and the tracking record belong together in one file, especially with the notice rule: Disable auto-renew and let the package expire, or use the cancel service flow.
The cancellation letter
What the letter to Namecheap says: one clear cancellation request, no reasons given, the account email, the domain or server name and the invoice number of the plan being cancelled quoted, and a request for written confirmation.
