I want to use another email address, rather than use the email address associated with PayPal.
For safety reasons we will keep the email address you used in PayPal. You can still add
the email address you prefer to use for keeping in touch. Please visit “My area,” and
follow the simple steps for adding an optional additional email address.
If you are unable to locate the solution you are looking for, and you have a Sonimus account, you can still get help by creating a client support ticket.
If you don't have a Sonimus account create a guest support ticket.
