Hi BostonBeanies,
We send email notifications about new sale to you right after your buyer went through all the steps in our Checkout process. At that point, we hand them off to PayPal and can't see what happens after that. Sometimes people don't complete payment step because they are confused by PayPal's system. So our thinking was - it's better let seller know that they had the sale, so they could get in touch with the buyer in case there is a problem on the payment step etc.
I believe our email notification just says "You have a Sale", not "You have a Payment", but I'll double check.
We'll also add a line in that email about Payment Status, so sellers, like yourself, know if person paid yet or not.
Thank you for your feedback and congrats on new sales!
