In addition to the newsletters we create manually, covered here, we also have daily and weekly emails that go out automatically using RSS.
For example, this is the feed for Saugerties Times: http://hudsonvalleyone.com/paper/saugerties-times/feed/
There are feeds for any paper, category or tag.
Here’s the one for Village Voices: https://hudsonvalleyone.com/category/voices/village-voices/feed/
As you can see, you can take any landing page and put “/feed” on the end to get the RSS.
You should know about their existence and have some idea how they’re set up in case you need to edit them, make new ones or cancel existing ones.
