Bulk Email Marketing

I'm looking for a software for bulk email marketing, which has all necessary features: statistics, html messages, bounce check, unsubscribe link, list import form a file, etc. I usually send 200K-400K per week REQUIREMENTS: - System must be running perfectly and work every day 24/7 - I must be able to log in and manage my contacts and send emails myself - High inbox deliver is very important. I will do 100K test sending with you, and I if I like the results we will continue working together.
