@Jake_Adams, Got you. PHPList is what you might be looking for, but I would suggest you discussing this with @ravisaive as he is managing more lists than me and he might be able to give you a good solution for your needs.
From what I know, many people use third party services such as MailChimp to send the emails. The reason behind this is the fact that their IP's are rarely blocked and therefore your emails can get delivered. I am not sure however if they provide the stats you are looking for. You can surely contact them and see if they can help as well.
