To update your email preferences, please click the link that says "Preferences" at the bottom of your email. This will redirect you to a page from which you can select the marketing-related emails you would like to receive.
You can also log in to your account, select the drop-down next to your avatar, select "Account Settings", then select "Edit Email Settings", and then select "No" after the question, "Do you want Experticity and its partner brands to send you news and offers via email"?
Note that you will still receive emails you explicitly opted to receive. You will also receive messages related to your orders or information about your account.
