- **Newsletter Frequency**: Choose from every day, three times a week, and once a week. Note that changes to this setting require you to restart your app to take effect.
- **Posts Per Newsletter**: how many posts each newsletter should contain.
Note that for this package to work properly, you'll also need to fill in the **Default Email** setting.
The package works with [MailChimp](http://mailchimp.com), which means you'll need to fill in an API key and List ID in your Vulcan app's settings panel.
Every `x` days, it builds a digest consisting of the top `y` items posted in the past `x` days that haven't yet been sent out in a newsletter.
It then creates a campaign in MailChimp and schedules it to be sent out **one hour later**, and sends you a confirmation email (to give you some time to check that everything looks good).
