Privacy. You don’t have to give out your email address, name or anything else to subscribe to an RSS feed.
Control. You can subscribe or unsubscribe whenever you want – instantly and without having to trust an email newsletter “unsubscribe” feature.
You can keep all your news and blogs (which are for information) separate from your email (which is for communicating with other people).
Your email inbox and filtering rules won’t be taken over by hundreds of email newsletters that need managing.
RSS feeds don’t get filtered out as spam by mistake.
RSS feeds are much easier to manage. Entries from each feed are automatically grouped together in chronological order showing which are new.
You can publish RSS feeds on a web page without doing anything to them, giving you a zero maintenance automatically updated information feed on your website.
RSS feeds can be used to provide you with a personalized news feed based on post categories or tags. Email subscriptions cannot be customized so easily.
Your feed reader will present every RSS feed in a consistent and highly readable way. Unlike emails, which are all individually formatted and don’t always display very well.
RSS feeds are an integral and automated part of most blogs or content management systems, interacting seamlessly with both posting and feedback mechanisms. Emails are neither.
