The newsletter form can be integrated easily into a book homepage (already present in the default homepage theme).
From your book dashboard, you can access the mailing dashboard, this page let you see stats about your newsletter subscribers and create messages.
There is two types of messages: Notifications and Newsletter messages.
When creating a new message from your mailing dashboard, you can choose the type of message.
Messages are sent in your name, so that readers can respond to it to contact you. But you can configure the reply-to email and set a bcc email.
Email notifications to subscribers will not sent immediately. All messages are sent at once, periodically (midnight PST). The message is sent to all subscriber to the book newsletter.
