Sadly, it's not currently possible to change your email address directly from your profile settings.
If you've got your heart set on changing your email address, write a short message to our friendly supporters here. Make sure you're logged in to Trustpilot from the email address that you're currently using (and not, say, from Facebook). When you submit your ticket, include the new email address you want to use in the body of your message.
When we receive your request, we'll get in touch with you to verify your new email address and to confirm that you're the account owner. Once we've done that, you can bid your old address goodbye and give your new email address a warm welcome.
