Bulk email markering

Would like help in creating bulk message. I use a couple of programs. One is sendblaster, and the other is MaxBulk Mailer. I like Sendblaster because it gives rating on spam, and I like MaxBulk mailer because it let my users unsubscribe easily by click a link in the email campaign. I need help on designing bulk messages so they dont get captured by spam. If there is a better way of handling my unsubscribers than MaxBulk mailer give, I would like too. Then I also would like help on updating my database with emails, and if you can extract new data from sites in Norway, Sweden and Denmark.
