If I have primie email PayPal for the login - first@abc (dot) com. And I set up second email PP which is not as the login - second@abc (dot) com. Can second@abc (dot) com be used to send and receive money? And make button 'buy now'? 'Subscription'? And for eBay? Do anyone have experience with this?
Yes of course you can use the second email for that. I believe you can add a total of 7 email address. To use the second button for the Buy Now or Subscription, just log into your paypal using the second email address, the password would be the same as your first. Then it will generate all the codes around the second email address. When someone buys from you, the second email address will receive the notification.
Yes, you can do everything using it, though subscriptions are routed via the primary email. Most often if a claim is opened against a transaction done by the second email, though primary email receives the notification.
