Newsletter, mailingList and contact management

I think it's a good question, and my research don't come to a FINAL answer, so i turn to you WordPress community. here is the question

I have about 300 email that i like to take from entourage to a catalog (contact database) WordPress seem fit to do that. After having a nice interface to get the first name, last name, telephone, email, company, etc in the database to manage contact in WordPress much like a CRM for the person on the road and in the office to get hold to that info anywhere

Then i like to get those person in the database to get a nice mailing newsletter each month in there inbox. Use the WordPress post to get the thing together, and hit a button, the post #123 send to 300 email, and get some stat on how many have open the email and so on...

So, WordPress is a nice platform to do that, but i will need a plugin(s) to do that... and listing in the plugins database of WordPress plugin dont help me

What i need, is THE best one to do that, cheep and efficiently...

so you guys, have real world experience with that... what plusin do that ?

thanks in advance
