e newsletter capabilities: import, amazon SES

Hello
E newsletter plugin questions:
1. I have my own html template - can I import and use in your plugin or am I restricted to your templates?
2. Can I connect your plugin to Amazon SES - do you have a settings guide for Amazon?
3. I want sign up for newsletter separate from website subscription (which I don't do anyway because of abuse and time management issues) - can your plugin do that?
4. I have 3,000 current members - is there a way to bulk import this data (csv) or is this a one-by-one job?
5. In the event that your plugin cannot do these functions I have listed, would you be so kind as to give me the benefit of your experience and point me to a newsletter plugin that can do all of these?

Many thanks
