Dynamic Tags & Autoresponder

I'm curious to know what dynamic tags are available for e-newsletter. I noticed in one screenshot it had a blog post, is it possible to dynamically post a weekly digest without manually adding posts?

Also any auto-responder feature that integrates with e-newsletter? I'd like to be able to send scheduled emails to users, and have different ones when conditions are met. I'm aware of auto-message however it requires that the person become a user, and its a single use implementation...meaning the autoresponder couldn't have varied email campaigns of the same content for different purposes. My ultimate goal is to add integration for Inboundnow.com plugins and piggyback off e-newsletter's features.
