PRO SITES - Plugin generated e-mails and editing them

Hi guys!

I would like to get a list of all e-mails that are being sent to both Merchant and Buyer during the different stages of subscription for example:
- Site suspended, payment needed
- Payment processed OK
- Payment failed
- Subscription is ending
- etc.

Where can I find a list of these e-mails and how can I edit them without editing the core files of PRO SITES?

I'm working on xpresso.pl domain - you have support access granted if you need to check anything.
