I have a serious issue with my paypal account in that the email address I registered with is one of my other email addresses that I don't check regularly. I'm worried - what notification does Paypal give when a payment is sent from my balance? Is it just an email? Thanks for your help!
Set a forward on your Paypal email address to deliver the correspondence to your active inbox. You should be able to receive notes from Paypal as they aren't always just payment notifications, you will also be alerted, for instance, in the event of a chargeback which you're required to deal with in a timely manner.
