How to cancel Sainsburys by mail
Find your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Sainsburys names the right account the first time.
Prepare the letter
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the Sainsburys account, stop every charge and reply in writing.
Mail it with tracking
Use certified mail for the EC1N 2HT London address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any Sainsburys charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Sainsburys, check these
- Use the same name and email as on the account. A mismatch can delay the request.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
