The addresses we hold
One place for Sanebox's mailing addresses: the Boston delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.

How to address the envelope
Write the address as printed
One address block, copied whole: 6 Liberty Sq 6009, Boston, MA 02109. If any line differs from the card above, start the envelope again.
Add the return address
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.
Buy the certified service
Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Boston is traceable from the article number until it is signed for.
Keep what the post office gives you
Hold on to the letter copy, the receipt and the tracking page.
The letter, written out
Copy the letter below onto one page, fill in the account email, the plan or product name and the invoice or order number from your latest receipt, and it is ready for the envelope. Our template builds the same letter on screen.
