Create an email address just for paypal transactions. There is no other way because PayPal will always send your email address so the merchant can update you about the purchase. This is a feature that makes sense to me.
It seems that you're saying that there's no way to do what I want. OK, thanks, but I'll clarify two points:
> Create an email address just for paypal transactions.
Yes, that's exactly what I have. I have an email address just for PayPal transactions. However, that same email is what allows me to login to PayPal. That's why I want to keep it secret for added security.
> so the merchant can update you about the purchase
I give my normal (non-PayPal) email address to the merchant on their order form. So they do have a way to contact me.
