How to cancel Smarty Cashback by mail
Start with your account details
Smarty Cashback will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Put the request in writing
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Smarty Cashback”: close the Smarty Cashback account, stop every charge and reply in writing.
Mail the letter with a receipt
Send it certified to San Diego, United States, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the delivery receipt
It shows the date Smarty Cashback received your letter. Check your next statement: no Smarty Cashback charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
