Which email address does my customer send a payment to?
You can ask your buyer to send their payment to any email address that you have added to your PayPal account. You can add up to 8 email addresses to your PayPal account.
If a buyer sends their payment to an email address that you haven’t added to your account, we’ll send an email to that address. After you add that address to your PayPal account, the money appears in your PayPal balance.
If a buyer is paying you for an eBay item, they must send their payment to the email address you selected when you listed your item. (You entered this email address on the Sell Your Item form.)
