If you think you’ve received a suspicious email or have been directed to a fake website, forward it to email@example.com and we’ll investigate it for you. After you send us the email, delete it from your inbox. If you clicked on any links or downloaded any attachments within the suspicious email or website, log into your account and view your transactions. It’s also a good idea to change your password.
Re: Does changing my primary email address mean I need to re create my buy now buttons?
If you want all your email notifications to go to your new email address then yes you would need to edit all of your buttons in your PayPal account and re-copy and paste the button code to your website.
