Testing with PayPal sandbox issues

Hi,

Im setting up an woocommerce wesite for a client. Im only going to use Woocommerce’s integrated PayPal feature to take payments.

Ive set up my client’s PayPal business account and I now need to test the site to make sure it generates the right emails etc…

A couple of questions:
1) I notice that in my PayPal account its automatically created 2 sandbox accounts for me (one for the merchant and one for the buyer). I presume I use the sandbox buyer’s card details to test on the site?
2) No emails get generated when I do a test transaction (Processing order, New order etc…). I read somewhere that emails wont get emailed when using a sandbox account. Is that right!?
3) I need to test this to see how it works if the user *doesnt* have a PayPal account. But on the PayPal screen after I click the Create Account button and enter details it wont let me past that screen even though all the details I entered are correct!

Any help would be appreciated.
Many thanks
