Is there a contact management system that does it all?

I am looking for ideas for Contact/Email system.  I had Top Producer but felt that is was not meeting my needs.  I found Moresolds, and loved the concept.  You can pay by the month, and with no monthly contract.  I am looking for one program to manage my contacts, plus give me the ability to build an email (easy to use) that I can send out to other agents and clients.  For example Just Listed, Open Houses, etc.  I am using Constant Contacts at the moment, but have not found it to be extremely user friendly.  Time is valuable, and I need some suggestions about what you are using.
