Aweber - effective tool for affiliate email marketing?

Hi - i would like to test the deliverability score of my SMTP servers by comparing to one of the main email marketing companies that are using shared servers. In my mind these are usually more problematic because they are so strict about the lists that you upload and the content that you use in the email creatives. If anyone else has any experience with this and could share some info that would be greatly appreciated! Thanks

Aweber is one of the top, its also very expensive and not good for large list, its best to manage a small dedicated group of followers
