I have Membership. 1. When someone subscribes

Hi,
I have Membership.
1. When someone subscribes to the membership (not WP), does the plugin automatically registers them for the newsletter, or do I have to do this manually?

2. Does the newsletter automatically integrate to different subscription levels? If not, can I do this manually? (I have some levels that receive the ezine and some do not.)

3. Can you send me a link to the manual, please.
