The option to merge, update or change an email address is not currently available. Please create a new Capital One Shopping account using your desired email address. If you have Shopping Rewards on your existing account, head over to https://capitaloneshopping.com/redeem and make sure to redeem them.
Rewards cannot be transferred from one account to another, so we hope you can redeem them before moving on to your new account. See Delete your account if you'd like to delete your account as you move to the one with the updated email address.
In order to create a new account, make sure you’re signed out of your old Capital One Shopping account and that you head to https://capitaloneshopping.com/onboarding. From there, enter your new account registration info.
