How to cancel Stamps.com by mail
Note your account details
Put the account email, the plan or product name and the invoice or order number from your latest receipt in front of you before you write: the request to Stamps.com is only as good as the details it quotes.
Prepare the letter
Your Postbye letter to Stamps.com asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Stamps.com”. It comes from our English template.
Mail it with tracking
Post it by certified mail to Stamps.com in Austin, United States, using the exact address below, and note the tracking number.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Stamps.com charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
