PayPal accounts are linked to email addresses, so a PayPal address is simply an email address that has been verified as a valid recipient of payments. After you sign up, you receive an email that allows you to verify your request for a PayPal account.
Can someone pay me on PayPal with my email address?
With PayPal, you can send money to anyone with an email address or a mobile phone number. The recipient doesn't even need a PayPal account to get started, and there are no fees for you if you pay with your PayPal account balance or bank account.
