Hi there. Thanks for the great question.
Yes, s2Member comes with two pre-integrated list servers. You can use MailChimp®, and/or AWeber®. You'll find instructions for integrating these professional services into s2Member, by logging into your WP Dashboard, and going to: s2Member -> API List Servers
Another alternative, is to use s2Member's API Notifications. Using API Notifications, you can integrate s2Member with just about ANY mailing list service, large or small. However, you will probably need help from someone who has experience working with web service connections, and understands basic PHP syntax. For further documentation, see: s2Member -> API Notifications in your WP Dashboard.
