I don't have a PayPal account. Why did I get an email from PayPal that I received a payment?

If you received a payment notification from PayPal that means someone has sent you a payment through PayPal. You can accept this payment by signing up for a PayPal account with the same email address you received the notification. Simply click Sign Up at the top of the PayPal page and follow the instructions.
For the first time you receive payment with PayPal, youll need to accept the payment manually. Simply go to the “Account Overview” page, and click the Accept button next to the payment you’ve just received. 
If you don’t recognize the payment and don’t want to accept it, you may just ignore the payment notification. The payment will be automatically cancelled after if it hasn’t been claimed by the recipient within 30 days.
