If you no longer wish to receive marketing emails from us, you can unsubscribe at any time by clicking the "Unsubscribe here" link at the bottom of the email, as shown in the image below.
I can't find the unsubscribe link
If an email does not include an unsubscribe link, it is a one time transactional email rather than a marketing email. These emails are sent only when necessary, for example after placing an order, and are not part of our marketing mailing list. Since they are only sent once in relation to a specific action, they do not include an unsubscribe option.
