Note that Perkuto/Digesto does not provide support on customizing your Feeds, but we thought it would be nice to share some tools that can help you out.
The BasicsWhat Is an RSS Feed?
RSS (Really Simple Syndication) is a type of web content published in XML format which allows users or programs to access online content in a standardized, computer-friendly format. It was originally used to aggregate content from multiple sources called news aggregators (RIP Google Reader). Websites usually use RSS feeds to publish frequently updated information, such as blog entries, news headlines, audio, video, etc., so that people can get timely updates from their favorite websites without having to manually check / visit them, but rather, to be "alerted" when new stuff comes in.
An RSS document is (also called a feed) will host various elements such as Title, Link, Description (Excerpt), Author, Publication Date, etc., which can all be extracted and reused by feed aggregators.

WordPress - Control Panel, Plugins, and How to Articles
To access the native feed settings, from your Admin Panel, go to Settings/Reading (WP 3.9.1 - May vary based on your Blog's version and settings)
You can typically control the number of posts that appear in your feed as well as the length of the article (Summary of Full Text).
Choosing "Full text" option will typically add the <content:encoded> element top your feed - which can then be available to populate your email with images and/or full article in your Digesto emails.
Thanks to the WordPress community, a great number of plugins and how-to articles are available to help you get the most off your feed.
