Send customised email alerts?

We’re trying to achieve the following:

• Send customised email alerts when a new post is added
• Sync the subscribers with our own database

We’ve so far checked out

Subscribe2 – http://ww.wp.xz.cn/extend/plugins/subscribe2/
database sync – http://ww.wp.xz.cn/extend/plugins/database-sync/

Would this work?

Any help?
