Alternative to Simplenews, or a way to send formatted mailing lists to subscribers? I have installed simplenews on Drupal 7 but it seems all the related modules: Simplenews Content Selection (to build up the newsletter using nodes or views) and Simplenews Template are outdated (Drupal6). 

Is there another way to use the nodes in the sites or at least creating a template to reuse with this module?

Or is there a way using other mailing list modules or custom code to build up newsletters from nodes?
