There are two types of email notifications from ShopBack.
1) Marketing promotional newsletters that keep you updated on our latest promotions, deals and upsized Cashback.
2) Cashback transaction notifications or account setting emails that notify you when you perform an action on ShopBack.
Unfortunately, we do not allow users to unsubscribe from the Cashback transaction notification emails due to security reasons. We want to keep users notified on any account activity that may take place.
However, you should not be receiving any more marketing promotional newsletters. If you still are, please reach out to us firstname.lastname@example.org and we will be glad to help!
