In the bottom-left corner, select your Profile Icon → Edit Profile.
Scroll down to the Basic Info section.
Select Email Address to edit your email address.
Add your new email address and confirm in the text fields.
Select Save to complete the change.
You will receive:
An email to the existing address that your profile email account has been changed.
An email to the new address requesting you to verify the change. Once you select Verify, your profile account email will be updated.
If you're part of the Brands Marketplace and you're changing your profile email address, you may also need to change your Marketplace Email Address if you no longer wish to receive emails to that address.
In the Basic Info section, select Marketplace Email Address.
Change the existing email address in the text field to your new one.
Select Save to complete the change.
This address will appear to potential advertisers when they view your profile in the marketplace unless you have the Marketplace Email Forwarding option enabled.
