I came across this old module:
https://www.drupal.org/project/simplenews_digest

However its really old and not working with Drupal 7. Is there a way to setup automated newsletters that follow a certain template? Example, i want to create a custom template and have that template apply to all the newsletters created in a certain simplenews category.

Every 30 days for example, the cron would trigger the newsletter to auto create based on views similar to how simplenews_digest did. So the newsletter is always sent based on the most popular content of the website in the last 30 days.

Anyone get a similar funcionality to work on simplenews using Drupal 7? And if so, how did you do? I cannot figure out how to do this, especially with it following a specific template per category.

Thanx.
